Micro Wind Power Generation

Donna asks…

going green home puzzle?

so my bf and i are thinking about buying some land in florida outside of the suburbs, so there are roads but no homes, and if we could buy and build a home how could we make it work without having to send electricity out there and with the water? i think we could get no grid tie electricity ( like solar) but i cant find anything on it, and im not sure about how to get running water and what to do about sewage. its kinda like a puzzle if you could help. im trying to learn as much possible.

Windmill Farms answers:

Is there anything in the natural terrain that you can take advantage of? If you had elevation changes, you could have two ponds and have mechanical windmills that pump water from the lower pond to the upper pond when wind is available. When you need power, you open a valve and run a micro hydro turbine, you don’t need much of an elevation change but it does take a lot of land to do this.

If one of the ponds is a shallow pond, say the upper pond, you could plant various water and bog plants to biofilter the water either as part of your freshwater supply or as your sewage treatment facility. Although, using an ecosystem to clean water can make cleaner water than municipal tap water, I wouldn’t want to rely on an artificial ecosystem to recycle waste water due to the possibility of short cycling pathogens but maybe if you have two such sets of ponds, one for potable water and the other for sewage treatment, both could be used for power storage and generation. You can find out about the plants to use in such regeneration ponds by researching natural swimming pools, the lower pond could be your swimming area (just not the lower pond of the sewage treatment pair). Considering what’s involved with sewage treatment it’s probably best to just use a traditional septic tank and just use the ponds for power, potable water and recreation.

Look up gasifiers, almost anything that burns including garbage and dried sewage can be gasified to make syngas, a mixture of hydrogen gas and carbon monoxide which can be used as if it was natural gas. It’s also possible to synthesize gasoline and diesel from syngas in what’s called a Fischer Tropsch reactor, a simple pressure vessel packed with rusty steel wool would work as an FT reactor if you can limit the temperature to 300 C and keep the pressure at 15 bar, you’ll synthesize gasoline and methane (this is known as high temperature Fischer Tropsch, low temperature is at 180 C and produces diesel and heavier waxes and oils that can be hydrocracked back into diesel). A side product of gasification is charcoal which when used as a soil amendment effectively sequesters the carbon as well as dramatically improving the soil, this is known as biochar.

The key will be to somehow have a career where you don’t have to commute in to work. You may want to focus on developing some form of web based business first, after that it’s a matter of your tolerance to the isolation.

David asks…

Why do so many people believe the Globalist Climate Change nonsense?

Scientists who question the common wisdom are marginalized and silenced. It is considered beyond the pale to suggest, for example, that the sun — that big ball of gas that supports the life of the planet, constituting more than 99% of the solar system’s mass — has much more effect on idiosyncratic temperature changes than human-emitted greenhouse gasses. And the fact that the carbon emissions theory was first seriously advanced by the Margaret Thatcher regime to bolster the case for nuclear power, back when the environmentalists had been worried about a “new ice age”?
But then,…that’s ancient history, and only a loon would bring it up.

Windmill Farms answers:

An excellent question.

I have been banging on for a while now asking the question ‘Just how much climate change is natural?’ No one seems to want to give an answer – and, indeed I find I get ignored too. The climate is always changing, only a fool would think it stays the same. Good grief, the North Sea is only 14 000 years old, after all, and the Romans grew vines right across the UK.

I think the reason so many believe in this is simply good marketing. It is like the faulty ‘Speed Kills’ mantra. Make a wrong decision to raise a few taxes and then persuade everyone you were right all along. No one wants to admit they are wrong, particularly as there are too many self-interests tied up in it.

A question that exposes the whole debacle is power, as you mentioned. The previously derided nuclear power stations are suddenly the country’s great hope. Less CO2 emissions, don’t you know? As a matter of interest, one of the ministers at the Department of Energy and Climate Change (good grief) is Joan Ruddock – didn’t she used to be the chair of CND? In any case, Greenpeace have asked why we are ignoring other solutions that are cheaper, faster to implement and more environmentally sound all round. These include micro-generation and community Combined Heat and Power stations. I do not include wind generation as that has flaws and is inefficient. No one in government seems to be willing to consider these or any alternatives. But surely if they are better for the environment and are cheaper….

No, beware the man talking into your ear – especially if he has a pin striped suit.

(As a footnote, by the way, a scientist friend told me that the best way to get funding for your project is to link it somehow to global warming – even if it has nothing whatsoever to do with it.)

Daniel asks…

What is in store for the American farmer under Obama?

The American farmer feeds and clothes this country. Will he get higher prices for his crops at a lower cost to produce them?
If you don’t like farmers don’t talk with your mouth full.

Windmill Farms answers:

Ensure Economic Opportunity For Family Farmers
Strong Safety Net for Family Farmers: Obama and Biden will fight for farm programs that provide family farmers with stability and predictability. They will implement a $250,000 payment limitation so that we help family farmers — not large corporate agribusiness. They will close the loopholes that allow mega farms to get around the limits by subdividing their operations into multiple paper corporations.
Prevent Anticompetitive Behavior Against Family Farms: Obama is a strong supporter of a packer ban. When meatpackers own livestock they can manipulate prices and discriminate against independent farmers. Obama and Biden will strengthen anti-monopoly laws and strengthen producer protections to ensure independent farmers have fair access to markets, control over their production decisions, and transparency in prices.
Regulate CAFOs: Obama’s Environmental Protection Agency will strictly regulate pollution from large CAFOs, with fines for those that violate tough standards. Obama also supports meaningful local control.
Establish Country of Origin Labeling: Obama supports immediate implementation of the Country of Origin Labeling law so that American producers can distinguish their products from imported ones.
Encourage Organic and Local Agriculture: Obama and Biden will help organic farmers afford to certify their crops and reform crop insurance to not penalize organic farmers. He also will promote regional food systems.
Encourage Young People to Become Farmers: Obama and Biden will establish a new program to identify and train the next generation of farmers. They will also provide tax incentives to make it easier for new farmers to afford their first farm.
Partner with Landowners to Conserve Private Lands: Obama and Biden will increase incentives for farmers and private landowners to conduct sustainable agriculture and protect wetlands, grasslands, and forests.
Support Rural Economic Development
Support Small Business Development: Obama and Biden will provide capital for farmers to create value-added enterprises, like cooperative marketing initiatives and farmer-owned processing plants. They also will establish a small business and micro-enterprise initiative for rural America.
Connect Rural America: Barack Obama and Joe Biden will ensure that rural Americans have access to a modern communications infrastructure. They will modernize an FCC program that supports rural phone service so that it promotes affordable broadband coverage across rural America as well.
Promote Leadership in Renewable Energy: Obama and Biden will ensure that our rural areas continue their leadership in the renewable fuels movement. This will transform the economy, especially in rural America, which is poised to produce and refine more American biofuels and provide more wind power than ever before, and create millions of new jobs across the country.

Paul asks…

Which is the best laptop?

i want to buy a laptop but i am confused which company should be preferred …del,vaio ,hp,acer,compact etc

Windmill Farms answers:

According to me
When it comes to laptops, each model packs in diverse sets of functionalities.

Cutting across the bewildering number of options in the market, here are some latest value-for-money laptop options that compliment user’s computing needs.

MSI WIND U270; price: Rs 22,999

Who should buy it?

If you want a small and light portable computer, check out the Wind U270.

It’s ideal for those looking for a second PC unit that can be packed for out-of-office days.

What to expect?

Micro-Star International is a Taiwan-based computer hardware that has a reputation for making some decent gaming notebooks.

But the MSI Wind U270 is an entry-level netbook, sports a 12.1-inch LED backlit display, runs on AMD’s 1.6 GHz E350 dual-core processor, with a 1.3 megapixel webcam for those interested in video applications and a 4GB RAM alongside a 320 GB drive.

The netbook comes pre-loaded with Windows 7 Home Premium.

There’s no compromise on connectivity since U270 packs in 2 USB 2.0 ports, an USB 3.0 port, HDMI output, Ethernet and weighs just about 1.3 kg.

While the integrated Radeon HD 6310 Discrete Class graphics card is nothing to boast about, it will allow playing games.

However, you will have to live with low details and a mediocre resolution.

Since long battery runtimes is what a netbook is expected to deliver, the integrated video card helps in maximising U270′s battery to about six hours (normal web browsing and light video usage).

The Wind U270 also comes with MSI’s i-Charger technology that promises to drive more power through USB slots that in turn charge devices up to three times faster.

HP Pavillion DV6; price: Rs 46,000

Who should buy it

The device is perfect for those who don’t want to compromise on a notebook’s processing speeds, graphics and sound output.

Road warriors may have to look elsewhere.

What to expect

When you buy this 15.6-inch display with a brushed aluminum look and feel laptop, get ready to be wowed by what the 2nd generation Intel Core i7 processor does to the notebook.

You will love how HP dv6 breezes through basic computing tasks like email and web surfing.

Vertical Wind Power Generators

William asks…

How do wind turbines work?

I want to know how the wind turbines work, so far all I know is that it takes kinetic energy from the wind and converts it to electrical energy used to power things.

Windmill Farms answers:

Horizontal wind turbines are the more common design, and use angled propeller type blades to create friction when facing the wind, resulting in the spinning motion.

The vertical turbine design uses the wind to spin on a centre point on the ground, resulting in the whole construction spinning round.

The process of electricity production is significantly similar in both designs. The construction only makes a difference in the position and design of the blades which are used to create friction with the wind.

A good way of thinking about the basics of wind power is by comparing a wind turbine to an electric fan.

How wind turbines work.An electric fan uses electricity to create the blowing motion (which is your wind), and a wind turbine works in the opposite direction, using wind energy to blow the blades, which are attached to a generator, creating the electricity.

So when the wind turbines blades are spinning, what happens next? Well the blades are attached to a long shaft (in horizontal wind turbines, pictured above). Inside the long neck of the wind turbine design, the shaft begins to turn which is connected to a generator, and this generates the electricity.

So there is the basic understanding of how wind turbines work. Wind power generation is a fairly simple process, and some people have had great success in building a home wind turbine from scratch.

Wind power is seen as a very good source of renewable electricity, yet many people still prefer the convenience, and reliability of solar panels, when choosing a renewable energy source for their home.

Donald asks…


Are there any free plans available detailing on how to build a diy vertical axis wind turbine using the stator etc. from a Fisher & Paykel Smart Drive washing machine,also any info on other parts (e.g. dump load resistors etc.) that would be needed and are available in Australia,possibly secondhand.Thanks.

Windmill Farms answers:

I haven’t seen one using a Fisher and Paykel washing machine but I have found this amazing two part tutorial on YouTube which walks you through how to make your own Vertical Axis Wind Turbine (VAWT) using materials costing less than $100.

The guy made his own gears using plastic cutting boards, the Savonius “sails” were made from large plastic barrels and he used a PVC pipe for the drive shaft.
The guy bought a cheap permanent magnet generator from eBay.

Check out his two part video series on creating a homemade Savonius VAWT;

Part 1

Part 2


A great source for other permanent magnet generators is Wind Power Blue;

Richard asks…

what is better a Vertical or a horizontal windmill?

need to know thx

Windmill Farms answers:

I imagine you mean vertical axis windmills to horizontal axis windmills. It all depends on where you would place the wind turbine. There are locations where a vertical wind turbine would be more beneficial (such as on a cliff). But for the vast majority of locations, a horizontal windmill is more efficient. Here are advantages of both.

-generator close to the ground
-more bird friendly (this is a HUGE exaggeration of windmills; wind turbines kill very little birds)
-does not ‘see’ wind direction (does not need to change directions like horizontal does; therefore more efficient in turbulent wind areas where wind changes direction a lot)

-more efficient (can reach power coefficient of 0.5 while vertical has only reached 0.4). Look up Betz limit
-not as noisy
-generally easier to construct

Betty asks…

What are wind turbines used for?

Windmill Farms answers:

A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is used to produce electricity, the device may be called a wind generator or wind charger. If the mechanical energy is used to drive machinery, such as for grinding grain or pumping water, the device is called a windmill or wind pump. Developed for over a millennium, today’s wind turbines are manufactured in a range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging or auxiliary power on sailing boats; while large grid-connected arrays of turbines are becoming an increasingly large source of commercial electric power.

Joseph asks…

How do I power a lighting fixture with a wind turbine?

I don’t need a lecture on the wonders of “green energy”, the benefits, blah, blah, blah. I am not hooking up to the “power grid” and I really don’t care about the “community”. I want a nuts and bolts answer. I’m making a small vertical spin wind turbine, and I just want to power one or two security lights. No, I don’t want to use solar power, too unreliable. What kind of generator and voltage regulator do I need? Do I need storage batteries? Wiring? Etc. Thanks!

Windmill Farms answers:

Sorry, but wind insn’t any more reliable than solar, and a lot of the same problems apply.
Your turbine set-up needs to gather/store enough energy to run your lights for the night.
For a home-built set-up, your best bet is an automotive alternator/regulator and batteries.
Use a 12V. Controller and lamps, and save the expense of an inverter.

Is Wind Power Green

Helen asks…

Which is more greener to eartch Solar power or Wind power?!?

im doiinqq a sciencee project on dat enn i wanna knoo how err which onee is better 4 earth!!(;’ enn my teacher said it has 2 be in likee Environment project err watever:b
Soo pleazse help mee enn explain which is better Solar Power or Wind Power?!(;’

Enn i havee bad qrammer i knoo i justt writee likee dis!!(;’

Thank yuee for yurr help!!(;’
What i still don't get is that i mean Solar power can only be used for like when the sun is out and Wind power can’t it be used when da sun isnt outt and wen its out?! Thats whyy im still quessinqq which is better??!

Windmill Farms answers:

Well, it’s not about being “greener”… Both ways are great for the environment.
The thing is that wind power requires a huge outdoor place like an open field because nothing else should “block” the wind coming.
So, i can tell you that solar power is better because u can place it everywhere, like on the roof or a garden. Get it?

Good luck with the project.

David asks…

Wind/Solar Power?

I just posted this in green living, but figured I’d also through it up here since I am a mechanical engineering student and would like to hear from people in the same field.

I’m very interest in these two topics and would like to know if anyone has any suggestions as to where I could learn as much as I can about these two. I prefer a book, but if you’ve found something you like better I’m all ears. I would like to be able to take some time to learn about these, then eventually in a year or so be able to build something capture, store, and maybe us the energy created from one or both of these. Thanks in advance.

Windmill Farms answers:

There are some good comprehensive articles on power generation on wikipedia.



This information is all public domain so you can use it for your project or whatever.

Richard asks…

Would the increase of nuclear power be bad?

Well im on doing a debate about the increase of nuclear power and im the negative, i just need a little help. Thanks

Windmill Farms answers:

No it wouldn’t.

Nuclear power barely emits any green house gasses directly. Even taking into account the mining & milling, plant construction and decomissioning it is 66 g CO2e/kWh which is comparable to renewables. Electricity generation emits 9,500 million tons of of CO2 annually and thanks to the small number of nuclear power plants in the world, providing 13% of the worlds electricity, carbon emissions were cut by 2 billion tons per year.

France generates 80% of its electricty using nuclear power and has the lowest greenhouse gas emissions per person in Europe as well as cheapest electricity. Since introducing nuclear power in France the air pollution has been reduced fivefold. Sweden relies on mostly nuclear and Hydroelectric power for their electricity and emits around 6 tons of greenhouse gases per capita. Denmark which is leading the way with wind technology (20% wind) has the highest greenhouse gas emissions per person in Europe. Denmark emits 11 tons of carbon per capita because of a still large reliance on fossil fuels. Environmentalist have been so against technology and nuclear power they lost sight of fossil fuel growth such as coal, oil and gas that emitt enormous amounts of greenhouse gasses.

Since the March 2011 Nuclear shutdown, Germany’s power imports from Poland increased by 500 megawatts a day. Poland hopes Germany will continue this trend, which is boosting its power sector and its coal industry. Poland generates 90% of its electricity using coal and the Polish Prime Minister, Donald Tusk, said that Germany’s decision will put coal-based power back on the agenda. I can’t believe people are seeing Germany as a shining example for clean energy. If Germany falls back on dirty coal-burning plants isn’t it trading a potential risk for a real one. Germany has also imported around 2 gigawatts of electricity from nuclear powered France since its plant shutdown.

Annual waste from one reactor will fit into a pickup truck and the fuel from 50 years of reactor operation could fit in a single football field, amounting to 77,000 tons. We discard 179,000 tons of batteries per year and they contain toxic heavy metals. When solar panels are decommissioned after the average 25 year lifecycle they also must be disposed of in toxic dumps as they contain highly toxic metals, gases and solvents that are carcinogenic. Some of these toxic substances in solar panels will never decay, having a never ending life span.

I find it interesting that even after Chernobyl the Ukraine still relies on nuclear power and is planning to increase their reactor fleet from 15 to 22. In June 2011, three months after Fukushima, a pro-nuclear politician won in a landslide election to be Governor of the Aomori prefecture in Japan. Aomori has 1 nuclear reactor and 4 more planned. A pro-nuclear mayor who supports building a reactor in his province won a landslide election against his anti-nuclear opponent in Yamaguchi Prefecture. Then in August 2011 a pro-nuclear Prime Minister was elected in Japan, Yoshihiko Noda, who stated he would reduce reliance on nuclear energy but never get rid of it completely. It’s amazing that 30,000 protesters against nuclear power seem to have more power than the rest of the nation. The polls and images that the media choose to promote are all of Japanese protesting nuclear power.

Until smart-grid technologies and energy storage systems improve and spread widely, wind and solar energy will be too intermittent to provide anything like the reliable base-load power offered by nuclear and fossil fuels. Hydropower plays a significant role in the energy mix of the United States and several other countries, but environmental concerns about the damage caused by dams have severely limited its growth.

India has just announced they are constructing a Thorium reactor which should be up and running by 2020. Thorium reactors can’t melt down, produce less waste than uranium, can’t be used in warheads and is even cheaper.

As soon as the start up costs of a nuclear power plant have been earned back, nuclear power is very cheap. Thats why France has the cheapest electricity in Europe and is 80% nuclear. A cost will be assigned to greenhouse gases, through either a direct tax or a so-called cap-and-trade system, which would set a limit on emissions while allowing companies whose discharges are lower than the cap to sell or trade credits to companies whose pollution exceeds the cap. Major carbon emitters like coal-powered electricity will be more expensive compared with low-carbon sources such as nuclear power, wind power and hydropower.

At the most 60,000 acres would be required to produce the same power output as a large, 1.2 gigawatt, conventional power plant which occupies less than 200 acres of land. That means that wind turbines would use about 300 times the amount of land as conventional power plants.

Good luck

Donna asks…

Are wind power and other green technologies an efficient way of producing energy?

Windmill Farms answers:

They can be, but these technologies are still in their infancy.

Like computers and the internet, they will take a great deal of additional research to become efficient enough for the free markets to use them for profits.

With computers and the internet, and many other technological developments, our government sponsored research through the military and grants. Then, once something was profitable, it was let go for the private sector to take over.

Of course, no company sold wireless phones for decades – until our government-sponsored programs got it to where it needed to be! Back in the Carter administration, our government sponsored research into solar and wind power; however, because of the power of the oil industry, and Reagan being their hero, he stopped all the research. Soft contact lenses were researched for years through government grants. Then, when they were safe, private companies took over.

Can you imagine where we would be today if we had continued helping green technologies? It is very possible there would have been no 9/11 because we could have been energy self-sufficient way before that!

It is a bunch of BS that the private sector will do this on their own – especially now. If they can’t make money on something quickly, they will not put the time and money into research!

Paul asks…

Who giggles at US cons still giggling at green energy while Denmark is now fully 50% wind power…?

…and while Germany sets world records for ratio of solar power?

“When you think of the most innovative places around the world for clean-tech, Denmark, where 50 percent of the energy comes from wind, might come to mind. Or maybe you’d think of Iceland, which is almost nearly 100 percent powered off geothermal, or perhaps Germany, which recently set a new world record in power generated from solar…”


Who giggles at anti-innovation US working class conservative neanderthal knuckle-draggers?

Windmill Farms answers:

Apparently you are willfully ignorant of the problems with wind energy. Compression and the whole bit. T. Boone Pickens was a big backer of this scam and it is a financial scam with very limited energy returns.

You also left out the “warts” of the German solar “success.”

You have basically taken a child’s enthusiasm and knowledge base and declared the supremacy of these two dead ends.

I thought wind and solar were great too, then some environmental activists pointed out the major draw backs.

But by all means, continue to be ignorant and see where you end up.

Uses Of Wind Energy In Everyday Life

Ruth asks…

How can we use science in our every day life?

Today is earth day and I wanted to know ways to use science in our everyday life. weather it be helping the environment or anything else.

Windmill Farms answers:

I like your doggie. You can make a compost heap using leaves and table scraps,,no meat..but things like coffee grounds are good and egg shells. Google how to make one if need be, but after the heap ripens, it becomes compost giving back to the earth fertilizer for more crops. You could use the compost in your every day life.

Things already happening that portray science at work are windmills harnessing the power of the wind for energy and water power used in places like Hoover Dam for electricity.

Mark asks…

What changes can we make in our everyday life to help save the rainforests?


I just got done reading the article above and it wouldn’t be the first time I’ve heard this news… I find it sad and alarming. I’ve made a lot of changes in my life but I don’t know what else I can do, short of moving to these countries where this is happening and spiking the trees and/or shooting at the loggers. As much as I’d love to take that kind of action, it’s not realistic nor is it legal. So I’ve decided to make changes like recycle and buy recycled materials since paper comes from trees, no longer eat meat because it demands the clearing of forests, and donate and buy my clothing from thift stores so as not to support an industry of consumption.

I know there’s more small, legal changes that I can be making and I’d love to hear your ideas…

Windmill Farms answers:


Looks like you have you eyes open. Can’t say that about to many people in society today. Most of us walk around with blinders until a catastrophe hits, then we wake up pretty quick. Unfortunately we go blind again a few months later…

Let me start off by saying we (my family and I) live 100% off of the grid and are completely self-sufficient with a 0% Carbon footprint. I believe this is the first step anyone can make “help the environment”. Once you convert your own life style to a greener more eco friendly route, you can start helping others.

Without getting to in depth here, Using alternative fuels in your vehicles and harnessing your own electricity from the sun, water, earth and wind are the 2 are key elements in making a green transition and erasing your carbon footprint.

I’ve been installing Solar panels. Solar stoves, Solar batch and inline hot water heaters. Solar radiant heating. Solar home heating and AC, along with home made wind gens and other alternative energy items for the last 3 years in apartments, homes and rentals.

You can even make the above projects on site with simple parts from the local hardware stores or auto stores or junk yards. For more info check out some guides I wrote / compiled on how to DIY http://www.agua-luna.com/guides.html…

Again these projects can be accomplished anywhere by anyone.

If you absolutely can’t do anything in your home at least you can put alternative fuels in your car. Most major automotive manufacturers (Chrysler, Ford, and General Motors, etc) recommend the use of bio fuels, and nearly every car manufacturer in the world approves ethanol blends in their warranty coverage.

In fact your probably even driving an ethanol car and didn’t even know it.

The trick is finding fuel.

I’ve been producing biofuel for about 3 years now, it’s not extremely difficult. Basically you need general household ingredients, a processor (or still for ethanol) and some used oil. Blend it, let separate, screen and use. I complied a guide a while back to help walk you threw the process step by step, just email me or check out..


as for recyling the best way i’ve found without taking money from your won pocket is to join a free freecycle group in your area or visit the habitat for humanity. See..



If you’d like help in making your self sufficient steps, feel free to contact me directly. I’ve written several how-to DIY guides available at http://www.agua-luna.com on the subject. I also offer online and on-site workshops, seminars and internships to help others “help the environment”.

Hope this helped, feel free to contact me personally if you have any questions if you’d like assistance in making your first self sufficient steps, I’m willing to walk you step by step threw the process. I’ve written several how-to DIY guides available at http://www.agua-luna.com on the subject. I also offer online and on-site workshops, seminars and internships to help others help the environment.

Mandy asks…

what are some of the ways that people reduce their use of fossil fuels?

Windmill Farms answers:

People can suppliment their everyday lives with alternative energy sources, such as solar or wind energies. Homes and businesses can be designed and built for maximum energy efficiency and heat utilization. Older homes and buildings can be retooled with energy efficient windows and doors. There are so many ways that people can reduce their dependence on fossil fuels… It just take a little bit of determination and brains.

George asks…

Can solar energy every make oil/gas obsolete?

(Note: This is not a political question, it is a scientific question)

The USA has spent $100 billion to $200 billon dollars in the last 20 years on military action in the middle east, primarily to protect our oil interests in the region.

If the US had committed $200 billion to solar energy research in, say 1990, would we be less reliant on oil and gasoline today and if so how must less reliant?

Windmill Farms answers:

Solar power has the theoretical ability to displace energy from fossil fuels but in practice there are other issues.

1) Solar power must be harnessed. To do this requires materials, some of which are currently made from petroleum.

2) Fossil fuels are also the feedstocks for many of the products we use in everyday life. Plastic and chemicals are usually from oil.

In practice, solar power could displace our energy dependence on fossil fuel much more easily than the demand for oil as a chemical feedstock. I’ve heard that at a long term stable price of $50-60 /barrel solar and other alternative energy sources (wind, geothermal, hydrothermal, tidal, biomass, …) can competer and displace our demand on oil.

If you take a real twist on the problem, the $100 to $200 billion we’ve spent creating unrest in the middle east may be the best way to reduce dependence on oil. The more instability in oil producing regions, the higher the price of oil. The higher the price of oil, the more the government doesn’t have to fund alternative energy work, because companies will naturally invest. In fact, for much less money the US could intentionally bomb and disable most oil producing facilities around the world and communicate that use of those materials for energy is no longer acceptable. That extremely unpopulatr unilateral policy decision could be extremely cost effective for supporting an alternative energy market.

On a more serious note, Europe does not require fuel efficient cars but does tax the use of gas. The US has had legislation for many years that requires car makers to be “more” fuel efficient. The approach in Europe has led to a significantly higher overall improvement in fuel efficienct.

Alternative energy in Europe is getting a similar boost in alternative energy from carbon taxes related to the Kyoto protocol.

The US is taking a more pork oriented approach of rewarding subsidized research grants to solar power work.

Why support solar power and an inefficient funding system? If we really think “oil” is bad, make it more expensive and the free market economy will very efficiently find and develop alternatives.

Susan asks…

For my physics class, I have to take some pictures illustrating physics in everyday life. Any suggestions?

I was thinking about things that could demonstrate velocity, friction, kinetic energy, potential energy, work, etc.

Windmill Farms answers:

An electric pencil sharpener in use has just about everything you are looking for.
Plus, you might want to look at
1. People opening doors.
2. Anything moving down the road; especially bicycles.
3. Many wind up clocks/timepieces have potential energy stored.
4. Even when you write your results that is friction, work, etc.

Wind Energy Stocks

Mark asks…

why would YOU buy energy stocks?

explain y energy stock are good to buy

Windmill Farms answers:

Crude oil prices are moving back up so there are companies (especially refiners) that have benefited nicely from its reversal of fortune. The best part of the oil and natural gas business is its predictability. Here’s how the story goes: A soaring economy increases demand, which causes prices to surge. Eventually, demand reaches its peak, the market is oversupplied and prices fall. It’s classic economics. Right now, according to my models, we are just past the peak of the fall, which makes this a fantastic buying opportunity. Granted it is tough to go against the alternative energy craze, but once the wind and solar profits have all come and gone, the nation’s oil and natural gas industry will remain, pumping away.

Linda asks…

Which is a better sector to work in…Steel or Wind Energy?

Windmill Farms answers:

I would say wind energy. I work in the steel industry in the uk and every couple of years there seems to be a steel shortage. I am in two minds as to whether our suppliers effectively create the steel shortage by saying there is going to be one or whether china is really buying it all up, but i do know that its a cut throat business and at the moment our company is being rationed as to how much we can buy from our normal supplier. Other suppliers aren’t taking on new customers, or their prices are way too high and we are running out of stock! At least you know we’ll never run out of wind!

Maria asks…

What “green energy” stock should I invest in??

Or should I at all. I have a feeling that this green energy movement is going to stick. What do you think. And which stock(s) are the way to go for “green”?

Windmill Farms answers:

I agree with what the 1st responder states. Individual stocks do contain a great deal of risk, especially in emerging markets such as green energy. For every one company that will survive 10 will fall by the wayside. I am not entirely in agreement with investing in an index fund in this area though, at least not at this juncture. If in fact 10 are going to fall by the wayside, then 9 out of 10 of the stocks in the index are going to fail. Not a promising opportunity.

I have to admit that I myself have positions in 3 companies, all outside of the U S. They all however are very expensive relative to their earnings. The least expensive of the 3 is TSL, a small Chinese company manufacturing solar energy solutions. Another is STP, another Chinese solar energy company, much larger and much more expensive. But both are absolute bargains compared to U S based solar companies. The 3rd is Vestas, a Danish company, which is the largest producer of wind turbines in the world. It is somewhat on the expensive side currently however.

I have studied The Andersons ANDE as a possible investment. The company among other things produces alcohol. It also has a large rail car fleet that it leases. One might consider railroads as the greenest of the green. Other railroad possibilities are NSC, UNP, BNI, and CSX. At least these companies pay dividends, have reasonable earnings, are more or less the only game in town in their respective regions, and are 7 time more fuel efficient than trucks and 50 times more fuel efficient than airplanes. Also they are the only form of transportation that currently is clean. They can run on electricity which can be generated by other clean sources. Unfortunately, I think others have caught on because they are all up significantly this year.

Ken asks…

Oil is skyrocketing, therefore green energy stocks should…?

Oil shot up like mad today, right. So, should green energy stocks (eg: solar, wind, energy cells: comv, eslr, ftek, fcel) go up or down? Why?

Windmill Farms answers:

Oil (and therefore Gas) prices have been very volatile in recent months. They are a mature technology, so there is unlikely to be any ground-breaking innovation in this area.

Green energy stocks on the other hand, as your long list suggests, are in many different technologies and are not fully developed.
Therefore, as Oil and Gas are immediately available, while green energy is still to fulfil its potential, I don’t think that there is the correlation you suggest. Once these new power sources become as plentiful as oil, they would be inversely correlated, as demand for one would depress the price of the other.

Windmill Farms answers:

Invest in A-Power Energy Generation System (APWR) stock is a great place to invest because the stock it blow 200 day average so in the short term it will increase really fast when it in the market earning again.in short_term you will earn 1-2 time the amount that you put in which in 1-2 year and of you put in a long-term you return it will be 10-15 time which it 5-10 years. The company is the biggest owner of wind turbine in china and the company is expending to other area such as U.S, Europe, and many more countries. The companies is expend their wind turbine to many different area the stock average return a year is about 20% but with right now the we are on the way to getting out of recession the average return is about 50%-120% a year.

Renewable Energy Credits

Mandy asks…

Should the government quit subsidizing renewable energy?

Im doing a project on this topic. Id like to hear your opinion and if possible, can somebody give me any links to where i can find info on this. Mines is that they shouldnt

Windmill Farms answers:

I actually think the government should subsidize renewable energy even more. They subsidize so many other things, including big oil, that it’s important they subsidize positive choices like renewable energy.

And, it’s more feasible for individual businesses and families to make the switch to solar or wind power on a small scale.

The renewable power plants and such will hopefully come, but currently, with the technology we have, it’s much more realistic for individuals to make the change on their own, and, tax credits are a nice incentive to help this change along.

Daniel asks…

Are tax subsidies for renewable energy a good idea?

Windmill Farms answers:

OK, let’s define “tax subsidy”.

The term “tax subsidy” is usually applied to a type of tax credit or deduction. In other words, it’s not that the government is taking money from someone and giving this money to someone else in the form of a subsidy. The government is simply taking less money away from that person in the first place…money that BELONGS TO THAT PERSON.

If this is what you are talking about, then YES, absolutely, I agree with it. What the government is doing is trusting the person or business that generated the income in the first place to take the initiative and perform a benefit to society. The government essentially eliminates itself as the middleman, saving all of us money in the long run.

Let’s look at an example:
Say that the goal of the government is to encourage purchase of wind turbines.

Under one plan they offer a $2000 dollar tax deduction to anyone that purchases a wind turbine (for argument’s sake let’s say that this results in $500 less in taxes collected a year). Administrative cost is negligible, just a few lines added to the tax forms and instructions.

Under another plan they offer $500 vouchers for the purchase of a turbibe. Administrative costs – considerable: you have to pay all the bureaucrats who have to issue the vouchers and direct the monies towards the different dealerships. There will likely have to be some sort of validation process requiring more administrative oversight. Then you likely have to deal with congressmen who are going to use their clout to try and wrangle more of these vouchers towards their own constituents. You can also count on someone in congress making sure that lower income individuals can take advantage of this offer, maybe increasing the amount of the voucher. The point is that once the tax money makes it to DC, the less efficiently it will be spent to benefit the citizens.

In addition, the tax deduction appears more enticing in the first place, since most will see the size of the deduction versus the actual portion of taxes they save. This could very well result in more home turbines purchased with less total cost to taxpayers – and almost the whole time the decision-making process belongs to the person who earns and spends his own money with minimal government intervention.

Less money going to DC is ALMOST ALWAYS a good idea.

Ken asks…

· Should we make the development of renewable energy sources an economic priority?

Windmill Farms answers:

Absolutely, the environment plays a larger role in daily life than we have given it credit. If we don’t shift our paradigm to a sustainability, we will only see more natural disasters, shortage of water, decrease in biodiversity (which has serious consequences!), more wars over resources, landfills overflowing with our unnecessary waste, etc etc etc.

We have to act NOW and it starts by each one of us considering our carbon foot print and how to mitigate our impact.

Donna asks…

economics questions about renewable energy?

Please read the following article, as it is what I am referring to ! I’ll have my questions placed below it ! Thank you!

“As the U.S. Congress tries to find a solution to the uneconomical nature of renewable energy, many experts say that the problem is already clear: the tax structure. In simple terms, the the wind and solar industries receive huge tax credits. But, they come with a catch: industry investors need adequate profits to take advantage of them, because the credit is used to offset tax liability.

Developers generally don’t have large enough profits to take full advantage, so they turn to banks, which invest large amounts of money in renewable energy through “tax equity” structures. Until recently, banks invested heavily in both the wind and solar energy industries. That meant, among other things, that the fate of renewables can be closely tied to the fate of investment banks. This explains why the collapse of Lehman Brothers caused problems at a Vermont wind farm.

The details are different for solar and wind, but both are having a hard time raising tax equity. At both state and federal levels, a jumble of tax and grant subsidies exist as incentives to invest in the renewable energy economy. Most are at the state level, with differing definitions of “renewable” and with capped programs that discourage long-term planning. All are vulnerable to abrupt policy changes.”

My questions:
1. Why doesn’t the government have this “catch” where the renewable energy developers can’t take full advantage of their tax credits? How is this different for fossil fuels? If (I’m just assuming this) fossil fuels have large tax credits as well, are they able to profit more since they can afford to take advantage of them?
2. What would happen if the government gave the renewable energy developers the chance to take advantage of the tax credits?
3. What do tax credits even do and what does tax liability mean?
4. What is tax equity/tax equity structures and what does they do?
5. What solution do you think needs to be done and why?
6. Why are there capped programs that fight against long term planning? Why does the state do this but not the government?
7. Through changing the tax structure, how can we get renewable energy to be the next big thing? Why does the government avoid solving climate crisis in this way though it is an obvious problem?

I am honestly just curious and completely oblivious to the financial world. I don’t know what taxes do, where they go, I don’t know what my w-2 forms do (my dad does them), and I’m so sick of being stupid. I feel like it’s an old man’s thing but I aspire to be like my dad and understand these things, maybe one day I can help…….

Windmill Farms answers:

1 and 2. You would have to check the tax code….my personal reason they get the credit is because their in bed with the govt. Private companies that is. The current gov needs money so they cant give out tax credits all willy nilly. Also research the actual making of a fuel efficent car causes more polloution than a standard vehicle. (from fox news and CNN) multiple companies the govt supported have filed bankrupt.

3. Tax credit in common terms is just another way of saying that you dont have to pay more money kind of like when you return a item and get store credit. Tax liability is somthing that could come back to haunt you when its time to file your taxes. Tax liability is theThe total amount of tax that an entity is legally obligated to pay to an authority as the result of the occurrence of a taxable event. If i sell a house or somthing i have to pay taxes on it. Gov always gets it share.

4. Yea thats too long to explain check investopedia.

5. Govt needs to get their hands out of everything and let bank companies fail… That why its called capatalism.

6. Speaking in regard to capped programs as in limit of funds or capped programs as in limit of emissons? The first one is to limit fruad waste and abuse. Govt is rampant with the stuff. Second is because the EU does it?

7. The IRS cannot favor a certain agenda because thats illegal look at the scandel going on now. As far as energy is concerned i believe the system will work itself out if we let it and stop throwing money at everything. Just sit and wait. There will be some smart people that come along and change stop gradually but just enjoy the moment now.

How to make a wind powered car?

I have a science fair coming up, and I would like to make a car not powered by batteries (pocket size, not full) and i think wind energy would be best. So I was wondering if anybody knew where I could look for information on this subject, or how to convert the motion from the propeller to energy.

Windmill Farms answers:

Japanese patent out for this since 98

Japanese inventor Hikoshichi Takahashi is patenting a wind-powered generator which sits on top of a car or truck (W098/32626). The device has either funnels or tubes, or both, which channel fast-moving air into a generator to produce electric power for the car. Excess power can be stored in the car’s battery. Unfortunately, Takahashi seems to think he can defy the laws of physics and get something for nothing: the energy generated will come at the expense of the extra aerodynamic drag caused by his roof-mounted apparatus.

How to make a rubber band powered car?

I have to make a rubber band powered car for 9th grade physics, okay? And it has to have at least 3 wheels, it must be powered by at least 1 or more rubber bands, and it must start from a resting position and can’t be catapulted or slung into motion, and it must operate without intervention. HELP PLEASE!!!

Windmill Farms answers:

Try a crank shaft. Take the two back wheels wrap a string around them or fishing wire is better. Now tie the other end of the fishing wire to the rubber band. Toward the front of the car have a hook to grab one end of the rubber band. Now when you put the car down pull the car backwords. This should wind the fishing wire around the back wheels while stretching the rubber band. Let the car go and it will go foword.

Here is a little sketch if you would

How to make a rubber band powered car?

Can someone give me a site where theres instructions on how to build a rubber band powered car? Or if you know how to make one can you please tell me? Think is for a science project and i dont know how to make one so if you know let me know thanks =D

Windmill Farms answers:

If you want to make the car run as efficiently as possible, then here is the secret. (First year engineering design project)

On the rear axle of your car, have a horizontal cone. Then wind the cone with a string starting from the thickest end, going to the thinnest. Attach the end of the string on the thinnest end of the cone to an elastic which is attached either to the front axle or somewheres else under the car.

If you know how gears work then this should be an easy way to make a super efficient elastic band powered car. The car starts slowly (without spinning out) and uses all of its energy by turning the thick part of the cone.

Also, A tangerine box makes a good cheap frame for the car :)

Linda asks…

We have to build a balloon powered car in science?

In science class we have been building balloon powered cars for a project. We have been taught that wheels larger in diameter conduct less friction where you don’t want it. The car has to go 5 meters with just 2 9-inch balloons attatched anywhere you want. Any ideas on how to make this work? We have so far made our base out of balsa wood so it would be light and our wheels are peanut butter jar tops.

Windmill Farms answers:

You’d want to make the car as light as possible – balsa wood is good – just wondering if heavy cardboard would make it lighter yet. You’d want the car to be as low to the ground as possible to minimize wind resistance when it is moving through the air. Having the wheels big in diameter is a good idea though – not only less friction but more traction – most high speed cars have larger wheels for that reason – the wheels would probably be the tallest part of the car in the sort of model balloon powered car I’m envisioning. You might want to try making the wheels out of balsa wood too – just to save weight – peanut butter jar tops are usually made of metal unless you found some that are made of light plastic. The car itself like I mentioned would be as low to the ground as you could practically make it for less areodynamic drag, with the balloons somewhere on the back end. This sounds like a fun project….

Micro Wind Power

Mandy asks…

micro nuclear reactor questions?

So I’m having to make a cardboard house for a science project that runs only on alternate energy sources. I’m using geothermal as a source, and nuclear. However, our sources can only be based for our homes, and not for several. So for geothermal, I’m using a ground source heat pump, and for nuclear, Toshiba’s micro nuclear reactor. However, I can’t figure out how the reactor circulates heat through the home, and I’m so confused! I understand the gist of how the liquid lithium-6 triggers the reaction, but I don’t know how that relates to heating the home, and how. Could you please help me? Thank you so much!

Windmill Farms answers:

I hope this is a model of the reactor, not a real one.

A nuclear reactor would never be used to heat a home. They are used to generate large amounts of electricity, some of which can be piped over the power lines and used to heat homes.

Use a wind turbine or solar cells, they are well suited for individual homes.

Does a coal fired power station affect the local microclimate?

The power station near my house is coal powered and pumps vast clouds of steam out of its coooling towers. The power station is closing down today…cant I expect any change in microclimate?

Windmill Farms answers:

Not really because the wind takes away the moisture released by the cooling towers. You can see a steam cloud because the moist air is cooling down as it gets out of the tower. But soon that moisture evaporates, until it reaches a certain height and the air cools down by adiabatic effect of a lesser pressure aloft to come under dew point temperature. That moisture will then, again, form a cloud. But a tiny one that will have no effect of the micro-climate and, anyway, it will now be far away from your location.

Vertical Wind Power Systems

Susan asks…

Is texas good place to use hydropower energy?

It’s doubtful. For hydroelectric power you need one or more big river systems. Those river systems need a good vertical drop and Texas is pretty flat – not much vertical drop there. Wind power would be a better choice in Texas.

Jenny asks…

How exactly does an f5 tornado form, and get to such a degree of power?

Right so this is a fairly general question.

How exactly does a tornado attain such force? Is it just a large enough cold front meeting enough warm air? And furthermore when a tornado such as a monstrous f5 is formed, does it begin with the power of a small tornado such as an f1? Or does it form as an f5 right out of the super cell?

Windmill Farms answers:

No one really knows exactly how they form. Not even meteorologists.

Here’s the best explanation I can give you.

First we have to look at the ingredients we need to be able to get a tornado.

•Warm air.
•Wind Shear.
•Cyclone (Low Pressure System)
•Lifting mechanism.
(I may of left something out.)

A tornado is nature’s most violent storm. It’s forms when warm moist air from the gulf of mexico collides with cooler drier air from canada. As these two air masses collide with each other you get wind shear. Wind shear is the change in wind direction and speed with height. (Horizontal Rotation).

Moisture is the fuel all thunderstorms need to form. Without moisture a thunderstorm can not form.

Severe weather requires warm moist air. Warm air rises. As the warm moist air rises into the upper levels of the atmosphere (3,000-10,000 feet) it creates instability in which air is warmer then the surrounding environment causing it to condense and form clouds.

A cyclone is a low pressure system that’s required to provide lift to allow the clouds to form into thunderstorm. This lifting mechanism causes horizontal rotation to become vertical rotation and thus you get a tornado.

The strenght of a tornado depends on different factors.

•How warm the air is.

–The warmer the air the stronger a tornado can be.

•How strong the wind shear is.

–The stronger the wind shear the more violent tornado can be.

•How close this wind shear is to the ground.

–If you have change change in wind direction and speed over a relatively short distance from the ground then the more likely tornado development becomes and the higher probability of seeing an EF5 tornado there is.

•Strength of instability.

–The stronger the instability the more likely you are to get supercells that can start to rotate.

—When you have extremely warm moist air that taps into cold dry air it can explode into thunderstorms.

•How strong the lifting mechanism is.

–The stronger the lift the more likely it is to get vertical rotation.

Like I said no one really knows how tornadoes form or how they get that strong. There’s a lot of theories out there though. This one I tried to explain above is how we currently think it happens.


The Storm Prediction Center is forecasting a major severe weather outbreak with the possibilities of tornadoes for parts of the Midwest, Great Lakes and Ohio River valley this Sunday November 17, 2013. Please stay tuned to later forecasts on this developing situation.

Sandra asks…

helpp please how are circulatory systems in animals and plants alike?

Windmill Farms answers:

Plant vascular tissues transport nutrients through the plant from the point of intake or synthesis. Xylem provides a bulk one-way flow from the soil to the leaves driven by passive transpiration. Phloem seasonally moves from source to sink with active loading of sucrose into the phloem.

A main function in a plant is an increase in a plant’s size away from direct contact with water, vascular tissue supports a thicker tissue system that a non-vascular plant can have with diffusion..
The secondary function of vascular tissue is structural, supporting the stem/trunk’s vertical mass against gravity and winds.

Animals have a circulatory system with a pump to move fluids, food, & oxygen around & around through our bodies and distribute them from the point of entry but plants don’t. Plants have very narrow tubes that run up from a root to a limb. This is why if a set of roots are damaged the limbs they supply with water will wither.

There is little or no transfer across the plant, the flow mainly either goes up or goes down because all leafy green parts of a pant generate food and exchange gases while every root draws water & nutrients from the soil. Plants need no more than a simple link between the water source and the food source.

Animals keep the circulatory system based the coelem, a body cavity isolated in the mesoderm between the outer body wall and the gut. It separates internal organs from external motions; it allows the digestive system and body wall to move independently by providing a firm structure for muscles to work against. In invertebrates the coelom had a secondary function of providing an internal hydrostatic skeleton. In this way the circulatory system is not influenced by external factors. So an animal’s is very different from a plant’s that relies on external factors to power the system.

Donna asks…

How much power is generated when a building starts to lean and where does it go?

Situation: 2-story beachhouse is slammed by 100mph winds. The building wall that is hit by the wind stays in place; but the opposite end wall blows out, causing a standard progressive collapse of the rest of the house. The house is wood-framed with manufactured truss roof, 60′ windward wall 100′ sidewalls, and 60′ leeward wall; 18′ from ground to roof connecting line, 5/12pitch, A-frame roof length-wise. Simple box-frame shape, with minimal door and window openings.

Particulars: Known is that 100mph winds generates about 950 lbs of horizontal force-weight impact to the windward side of building. allowable loads for this building is 975lbs horizontal resistance along sidewalls. wejght of entire building(minus the foundation) is 5-tons(10,000 pounds).

Windmill Farms answers:

Not sure if all that data means anything, I suppose you could calculate energy input into the system, if you could determine the deflection of the shear walls, the energy (strain energy) is then the integral of the force-displacement curve, (I think, it’s been a while since I actually used energy methods), the energy needed to move the house over is ‘stuffed’ into the nails in shear strain energy, the shear walls in strain energy of distortion, (shear strain is a subset of distortional strain), until the load is removed, (we’re saying the building doesn’t fall over, no permanent damage) then that energy is “released” back into the environment, or use to do the marginal work against gravity to restore the building back to the original vertical state.

“Power” isn’t generated because if you take away the strain energy, the building will be permanently bent out of shape.

It might make a lot more sense to look at a straw – bend the straw, you’ve done work against the straw to move it, but the straw (when it is still elastic) will straighten back out if you remove your force. That means the straw has (absorbed) the external work you have done and used it to perform internal work, when you remove the load, since the straw is elastic, it springs back to the original shape, using the stored internal work to perform external work, pushing the straw back to the original vertical.

What we are neglecting in this process is friction (heat, and sound) generated in the process of applying the load, and obviously, any part that is broken takes energy to rip it apart, and any part that goes flying also subtracts energy from the internal work done and converts it into kinetic energy. So energy in a house collapse goes

Does that make sense?

How does a windmill operate and what is its operation??

Windmill Farms answers:

A windmill is an engine powered by the wind to produce energy, often contained in a large building as in traditional post mills, smock mills and tower mills. The energy windmills produce can be used in many ways, traditionally for grinding grain or spices, pumping water, sawing wood or hammering seeds. Modern wind power machines are used for generating electricity and are more properly called wind turbines.

Early history
Windmills have been around for at least 1,300 years. The first windmills had vertical shafts and were reportedly built in Persia around the 7th century AD. Made of six to twelve sails covered in fabric or palm leaves, they were used to grind corn and draw up water. A similar type of vertical shaft windmill can also be found in 13th century China.

In Europe
Muttons Mill, one of the many drainage windpumps on the Norfolk Broads (United Kingdom)In Europe, windmills were developed in the Middle Ages. The earliest mills were probably grinding mills. They were mounted on city walls and could not be turned into the wind. The earliest known examples date from early 12th century Paris. Because fixed mills did not suffice for regions with changing wind directions, mill types that could be turned into the wind were developed. With some subsequent development mills became versatile in windy regions for all kind of industry, most notably grain grinding mills, sawmills (late 16th century), threshing, and, by applying Archimedes’ screws, pumping mills.

With the industrial revolution, the importance of windmills as primary industrial energy source was replaced by steam and internal combustion engines. Polder mills were replaced by steam, or diesel engines. The industrial revolution and increased use of Steam and later Diesel power however had a lesser effect on the Mills of the Norfolk Broads in the United Kingdom, these being so isolated (on extensive uninhabitable marshland), therefore some of these mills continued use as drainage pumps till as late as 1959. More recently historic windmills are being preserved for their historic value, which requires regular use because the wooden machinery is likely to be destroyed by woodworm and dry rot when the mill remains stationary for too long.

With increasing environmental concern, and approaching limits to fossil fuel consumption, wind power has regained interest as a renewable energy source. This new generation of wind mills produce electric power and are more generally referred to as wind turbines.

See Flood control in the Netherlands#Windmills for use of windmills in land reclamation in the Netherlands.

In the United States
Farm windmill, Sheridan County, Kansas, USA, 1939The development of the water-pumping windmill in the USA was the major factor in allowing the farming and ranching of vast areas of North America, which were otherwise devoid of readily accessible water. They contributed to the expansion of rail transport systems throughout the world, by pumping water from wells to supply the needs of the steam locomotives of those early times. They are still used today for the same purpose in some areas of the world where a connection to electric power lines is not a realistic option.

The multi-bladed wind turbine atop a lattice tower made of wood or steel was, for many years, a fixture of the landscape throughout rural America. These mills, made by a variety of manufacturers, featured a large number of blades so that they would turn slowly but with considerable torque in low winds and be self regulating in high winds. A tower-top gearbox and crankshaft converted the rotary motion into reciprocating strokes carried downward through a pole or rod to the pump cylinder below.

Windmills and related equipment are still manufactured and installed today on farms and ranches, usually in remote parts of the western United States where electric power is not readily available. The arrival of electricity in rural areas, brought by the Rural Electrification Administration (REA) in the 1930s through 1950s, contributed to the decline in the use of windmills in the US. Today, the increases in energy prices and the expense of replacing electric pumps has led to an increase in the repair, restoration and installation of new windmills.

In the heyday of the windmill, there were thousands of windmill manufacturers in the United States; today, Aermotor Windmill is the only manufacturer of conventional windmills left in the USA. GE Energy, a unit of General Electric, manufactures windmills for electricity generation.

Is Wind Power Really Green

Donna asks…

When is the White House going green ? i.e wind or solar power ?

or is this another do as I say and not as I do with the Libs ?
” Global Warming is BS ” you are my new buddy
LOL, Good one Saturn

Windmill Farms answers:

Carter put in a $30,000 solar water heater that naturally didn’t work 35 years ago
several presidents since then have have spent money on trying to make the white house more green.
As usual none of these expensive systems work very long or very well.
Heres a yahoo news story on it.


congress reported a couple of years ago that they were going to eliminate the carbon foot print of the government power plant.
They got a lot of good publicity from it then quietly decided that it couldn’t be done. Heres the story on that.


like all government feel good plans its a lot easier to say you’re going to do something than to actually do it & make it work.
But what the hay, they get all the credit when they announce these goof ball plans. So they never even bother to try & do what they say.
Its easier to just pass laws to make everyone else do it.

Betty asks…

going green???

how many of you are going green?
and tell me how you are helping out!
tell me what you have stopped doing
and what you have started doing!
plz and thx :)

Let me start off by saying we (my family and I) live completely, 100% “off of the grid and are completely self sufficient”

The house is built utilizing natures natural elements, in the shape of an octagon with 8ft wide arch doors on every wall to catch every angle of wind (typical 4 sided homes have half the chance as one with 8 sides. A circle being the most efficient design). Woodburning stoves, solar chimney, solar AC, solar heating, solar water heating (pool and home), solar stove, solar power, wind power, hydrogen powered back up generator, hydrogen back up water heater, hydrogen stove, 2 hydrogen powered trucks, 1 EV (electric vehicle) and satellite internet.

We also built many green small cabins on the ranch that we offer to family, friends and our on-site off-grid workshop guests, including one straw bale, one papercrete, earth bag and adobe, one cob and cordwood, one underground and rammed earth, one log and post and beam and one rock. Each one actually started as a test for what the main house would be and were later finished and turned into guest cabins. I later wrote a guide on how to build with alternative materials using alternative methods for next to nothing.

We raise meat and milk goats, chickens for meat and eggs, ducks for meat and eggs, trap havilina (wild boar pig), rabbit, quail. Brew our own beer from home grown products, preserve our fruits, vegetables, etc. Smoke and jerky the meat, make our own soap, cheese.

There are no utility lines, no water lines, no roads, tv, cell service, etc. On our ranch. EVERYTHING needed is produced here. All electricity comes from 27 solar panels, 2 main wind gens and a back hydrogen generator if needed (typically we can last 9 days with all luxuries of sunless windless weather, hasn’t happened yet). Water is caught and storaged from the rain. Hot water is made with solar batch water heaters with an on-demand hydrogen hot water heater as backup. Even our vehicles use alternative energy (2 hydrogen trucks, 1 EV electric vehicle converted). Because of this we have no bills, no debt and no mortgage.

Jenny asks…

How do I calculate required electric power needed to run computers with solar panel?

I’m trying to figure out required solar panel devices to run a set of computer.
For example, 45 watt power supply computer with 65 watt laptop and 70 watt lcd monitor.

Second question is..
Let’s say I purchased 45 watt solar panel set. Can I use just powerful power converter to use all? or do I need more solar panels to juice power?

Windmill Farms answers:

Hi I am the owner of Mountain Wind & Solar http://mountainwindnsolar.com (please be aware though that this website is still under construction).

What you need is a Kill-A-Watt meter. All you do is plug all of your appliances into a power strip, plug the power strip into the Kill-A-Watt meter, and then plug the Kill-A-Watt meter into the wall. The Kill-A-Watt meter will tell you how much power you are using. If you keep the Kill-A-Watt meter plugged in then it will add up the amount of power. You can also tell it the price of electricity in your area and it will tell you how much the appliance plugged in has cost you.

Kill-A-Watt meters are great tools that tell you a lot of information.

The cheapest one I have found online is at http://www.newegg.com/Product/Product.aspx?Item=N82E16882715001&nm_mc=OTC-Froogle&cm_mmc=OTC-Froogle-_-Electronic+Gadgets-_-P3+International-_-82715001 I am sure you could find one for pretty cheap on e-bay.

David asks…

Are there rebates/incentives for solar/wind power in the Dallas/Fort Worth area?

I’ve found information on federal tax incentives, but I’m particularly interested in rebates for equipment purchase and installation. The city of Austin offers this, and in other areas rebates are offered by the power companies themselves. I can’t find info particular to the Dallas/Fort Worth area, or energy providers in DFW.

Windmill Farms answers:

I’m looking into wind power myself, and honestly, there are not many incentives other than the personal incentive to help out the environment and maybe save a little off of the monthly utility bill. Have you seen this page?


You’ll see that the only incentives in DFW are the same that are available to most of the state – property tax incentives. There are also net metering laws (for utility buy-back), and I imagine that Green Mountain Energy would be the most generous:


Here’s a couple of providers including one that actually manufactures their unique design here in the metroplex:



Hope this helps!
