Wind Power Energy

Donna asks…

What are the basic element in wind energy conversion device?

I have to build a wind energy conversion device for my design subject. However, I can’t use toothed gears, gearboxes, energy storage systems (e.g. flywheels, batteries, pressurised fluids, etc), rolling
element bearings and existing (pre-made) fan impellers.

So I need rough ideas on what are the things that can replace those items which can make the device moving.

Windmill Farms answers:

Your basic design goal is to “Build a Wind Energy Conversion Device”. This is a broad goal as it does not specify if the end result needs to produce electrical or simply mechanical energy.

You are limited as you cannot use any rolling element bearings. This can cause a problem for horizontal wind turbines. To avoid this, you can use a vertical wind turbine similar to the following. Http://www.ecofriend.com/entry/pacwind-vertical-axis-wind-turbine-at-home/
The curved blades will “catch” the air flow no matter what the wind direction is.

To avoid the use of rolling element bearings, a vertical wind turbine can be supported at the bottom. Ensure both the spinning shaft and the housing are smooth and greased. Supports higher up will also be needed to keep the turbine level. These can be holes cut out of the frame which are close to the spinning shaft.

To transfer the power, use a pulley and belt system. This won’t violate the toothed gear rule. You will incure some efficiency losses as the belts and pulleys will slip.

On the other side of your pulley, you can hook it up to a small generator to generate power continuously as the wind blows, or you can attach if to some mechanical device to provide mechanical power. Just ensure the initial start-up torque isn’t too large.

Paul asks…

What order would you put these Energy Options in from most efficent to least?

I need help with my geography homework…!

They are:

Nuclear Power
Coal
Wind Turbines
Solar Power
Geothermal Energy
Hydrogen Fuel
Hydro-energy
Ethanol Fuel
Waste-to-energy

Please help me!
It’s an essay, so its not the whole homework. I just need help getting started!
Well, the best energy option to the worst in environment, economic stability and where it comes from

Windmill Farms answers:

1.Solar Power
2.Wind Turbines
3.Nuclear Power
4.Hydrogen Fuel
5.Hydro-energy
6.Waste-to-energy
7.Geothermal Energy
8.Ethanol Fuel
9.Coal

Betty asks…

How man’s search for energy is effecting the environment?

I need to know how our search for energy sources – wind power, coal, oil, etc. – is effecting the environment for a school project.

Detailed answers will be greatly appreciated.

Windmill Farms answers:

The verb you need to use is “Affecting” not “effecting”.

Effect is a noun. Always is, always will be.
Affect is the verb.

Laura asks…

Which of these fuels would you select for the generation of energy in the future?

Of these fuels/methods, which would you choose to use for generating energy (you can choose multiple)?

Fossil fuels
Bio-fuels
Solar power
Wind power
Hydroelectricity (water power)
Geothermal energy
Nuclear fuels

Please give reasons for your choice and also state the problems that might be apparent, but explain why this is the best option on balance.
Also, please give reasons against ones you didn’t choose.

Windmill Farms answers:

The best of these energy sources is solar power. It is, for all intensive purposes, unlimited, unlike fossil fuels and nuclear fuels (Yes, nuclear fuels are limited). Of all of the renewable sources of energy listed here (solar, wind, hydroelectricity, geothermal, and, I suppose, bio fuels), solar energy is one of the cheapest.
Geothermal energy is very expensive, and is not very efficient. Hydroelectricity may be relatively easy to get, but, in the process of harnessing it, we disrupt the rivers’ ecosystems. Wind turbines are eyesores, and require a large amount of area in order to harness any useful amount of energy.
Nuclear energy… Chernobyl, Fukushima, etc., anyone? Oh, and what do you do with the nuclear waste?
Bio-fuels are still in their infancy, but, as far as I can tell, they will just be a replacement for fossil fuels (meaning more pollution).
Fossil fuels, well, we’re going to run out of them within the next century, plus, the extraction of energy from them produces a lot of pollution.
The only potential problems for solar power are cloud cover and night time. However, this can be (largely) circumvented by using enormous rechargeable batteries (well, something akin to them) to store excess electricity produced.

Lizzie asks…

How will wind energy affect our future?

Any lists of website that talk about wind energy and how it will affect the future.
or any ideas you guys have ?

Windmill Farms answers:

Wind power or wind energy will affect our future with peace and wealth; since wind is everywhere and available for everybody, And when people know how to get profit from wind there will be free energy for everybody, you can always get your own wind power network at home for an average of $100 and forget paying your bills. Go to http://www.windpowercost.org
you will get free courses on how to do it easy.
