Wind Power Companies

Steven asks…

Where can you buy insurance for connecting to the power grid with a wind generator in Texas?

I have a friend who would like to install a wind generator for electricity, but the local power company will not let him connect to the power grid unless he can show that he has a million dollars insurance. Well, he cannot find any company that offers that type of insurance for any price. He has written to everyone he can think of but still no source of insurance. The reason he wants to connect to the power grid is to use it as his storage system so that he doesn’t have to maintain a whole bank of storage batterys. Does anyone know where he can get this type of insurance for a system that will be in the state of Texas?

Windmill Farms answers:

Call your electric company; the folk you would have had to call anyway to get connected & let them know that you would like a reverse meter so that they can measure how much energy that you are back feeding. There is specific wiring for this that has to be approved through your county anyway & it is a safety feature for people working on the lines after a storm so you don’t inadvertantly electrocute a lineman who is trying to restore power around you. They will no doubt have the answers that you need or can advise you on where to look for the insurance. The way that you do a million dollar insurance policy is called an UMBRELLA POLICY on the homeowner’s. That isn’t hard. It is a property insurance that goes above what the homeowner’s insurance carries. The UMBRELLA coverage is a catastrophic event coverage that is called secondary insurance. It isn’t even very expensive as it covers after everything else has been exhausted first. Go to yahoo & google Umbrella insurance & then if that doesn’t work, look at commercial insurance companies in your area. I know that CNA which is a HUGE insurance company, they write in Texas & may be able to write your friend the policy that he needs. I hope this helps. I used to do underwriting assistance for them & I helped insure folk in Texas in particular.

Laura asks…

Anyone have a formula for cost-benefit analysis of buying a windmill for power generation?

I live in an area where a power company uses wind generators successfully. I’d be looking at about a 1.8 kw generator in an area where electricity is expensive. Initial cost is $13K. Would I be better off waiting a couple of years for newer, better, cheaper wind generators?

Windmill Farms answers:

1.8kW wind generator… Running at 25% load produces 1.8kW * 0.25 * 24hours/day * 365days = 3942kWh/year.

Let’s make that 4000kWh. You can probably sell that electricity for $0.07/kWh. Makes a total income of $280/year.

5% annual interest on $13000 is $650. Yep, you are going to lose roughly $370 per year… Not counting running cost for repairs etc.

Sounds like a great business proposition? I don’t think so.

If you are just offsetting your own consumption and electricity prices are around $0.15/kWh, you might just brake even. Barely…

In general I would not think that wind below 250kW is a good investment. Try 10MW+ wind parks and you are probably talking about a sound business model.

And some people simply want to do their share to improve global warming. They don’t need to be concerned about the financial downside. If you are one of them, go for it. It will make you feel a lot better.

Michael asks…

How to get into wind-power field?

I graduated from college 2 years ago, and my degree has proven mostly useless.

I’m 25, and would like to somehow work for a power company maintaining wind turbines. I like the green renewable aspect of it all. Any ideas on how to get a job in the industry?

Windmill Farms answers:

I assume you googled for power companies that have wind machines. So contact their personnel department and see what they have to offer.

The google wind machine manufactures, contact them.

Consider returning to college to study wind turbines. You didn’t say what your degree was in but if you go into an MA program you will be in the forefront of machine development and will have contacts in industry and management.

If you primary interest is maintaining them, you should find companies that do that and see if they need a trainee.

There is more than one wind farm in the US and there are many small operators.

Paul asks…

Are there any publicly traded companies who are major players in solar/wind energy storage?

With the emerging wind power industry, we are destined to see a select few companies make a killing with solutions to store wind / solar energy and disperse the energy as needed.

Mary asks…

What is the monthly yield on a 60K wind turbine if it’s planted in a wind farm?

I want to purchase a 60K wind turbine and plant it in 29 Palms, CA wind farm. If all the electricity produced is returned to the power company, what would the monthly yield be?

Windmill Farms answers:

Typically in 29 Palms, you get 8 hours of good wind per day (four hours in the morning, and four hours as the sun begins to set.) The wind speed needs to be around 25 mph to produce sufficient wind to generate at maximum capacity. You’d produce 60 kilowatts of electricity for about 8 hours a day with a 60k wind turbine. That is 8 hours*60 kw, or 480 kw/h. You’d sell that power at about $0.08 per kw/h, so you’d get (480 * $.08=) $38.40 per day from a 60k wind farm. You’ll see soon, as you do the math that it doesn’t justify the cost, unless the wind turbines are HUGE. (Remember the formula for calculating the area of a circle is pi times the radius squared.) The blades need to be large enough to overcome the ratio of the cost of the blades, and that works out to be about 80 to 100 feet long. If the blades aren’t that long, you won’t get the project to pay for itself (without tax subsidies or some other income.)

Now, building even one really big turbine starts paying off spectacularly: but it will be measured in Megawatts, not kilowatts. A GE 1.5MW machine pays for itself (cost is about $2,250,000.00.) There are other manufacturers building at that size and scope too, but GE is a good example.

A GE 1.5MW machine using the same math earns the owner 1500 kw * 8 hours * $0.08 per kw/h = $960.00 per day. In a 365 day year it would generate $350,000.00 per year, and pay off in about 6.5 years. (In actual practice, give it 8 years, because there are Operation and Maintenance cost issues that you must pay for: Someone has to oil the machine!)

Is Wind Power Really Green

Mary asks…

China going green?

I am doing a project on china and its new economic steps towards becoming a nation that runs on alternative energy sources. So i have 2 questions, economically, socially, and politically, what is driving China’s government to do this. And second for the same reasons what will happen to China if and when this happens.

Windmill Farms answers:

Economically it makes perfect sense for a developing country to go green. Why? It’s a renewable source. You don’t have to process anything or use up any resources to use solar power and other natural, renewable resources. It also makes sense for a country as massive as China (in terms of size and population) because of the amount of resources it takes to continue using coal/nuclear power could be tremendous. Investing in solar or wind power might cost more to start out but it costs much less to use. Politically speaking, I’m not certain as I am not familiar with their government. However, it seems that United States is one of the few countries that has an economy that has strong grips on fossil fuel and nuclear technology. Getting rid of it entirely can cause a major hiccup, mostly with the wealthiest people in the country who, unfortunately, contributes to our governments political agenda in a major way. Not that this can’t be changed, but the ones who can truly make a difference aren’t always the most informed, thanks to our governments silent and invisible sensorship, nor do they want anything to change when everything seems to be going well. I’m sure that will change if our delicate weather system and our fragile environment changes drastically in the next few years, and once we take the blindfolds off that our glorious leader has put upon us.

As for what will happen to China if this happens…time will tell. I think that this will give them the competitive edge on the global economy and welfare of the Chinese.

Betty asks…

ARE GREEN ENERGY INVESTMENT WISE?

Is a green energy investment good. Investing in the construction and development of wind and solar power stations. Green energy is on the rise. I have an opportunity to invest in a private fund that’s developing solar and turbine wind power stations. What are your thoughts?

Windmill Farms answers:

I am definitely not an expert on green energy, but it seems like there is so much money chasing these projects that really dumb stuff keeps getting funded and then going splat. I think the right thing to do isn’t to invest in green energy, it’s to make a company that pursues pie-in-the-sky technology.

If you can’t personally evaluate the technoilogy, you shouldn’t be in this sector.

George asks…

What do you think? Is wind power a good source of energy or not and explain why?

Windmill Farms answers:

Hi Jim bag
it is an excellent source of power in a place which is windy, as a radio amateur we have a local repeater which is powered by the wind.
There is this wind turbine on top of a hill and it powers some batteries which in turn store the power for when it is needed.
The site also had solar panels but some nice person stole those so it runs on the wind turbine 24/7 which is a very green source of power.

Richard asks…

How reliable is “gone green” Web hosting?

I’ve heard HostGator has gone green, that their servers are all wind-powered. Are there servers still reliable, or are there chances their servers will clunk out?
Take your spam and shove it where the sun doesn’t shine, and I don’t mean the closet.

Windmill Farms answers:

Hi Anonymous,

Only their shared and reseller servers go green, except dedicated server… For now.

By saying “wind powered”, just because there isn’t wind blowing doesn’t mean the server will be down. No. If that’s the case, as one of the top 10 web hosts in the world, wouldn’t they be digging their own grave?

Basically, Host Gator buys the certified renewable energy credits (RECs) from a renewable energy generating company to power their servers. You can learn more about its green hosting here (very interesting info):

=> http://tinyurl.com/host-gator-go-green

In a nutshell, there’s always power generated for all their green servers, just as before. A crazy climate change will not affect the reliability at all.

In other words, if their servers’ reliability used to be 99.9% before they go green, it’ll still be 99.9% after going green.

Hope that answers your doubts. Cheers ;)

Helen asks…

Will we need fewer power generating stations if….?

…. we go totally “green” and rely 100% on wind and solar?

If we do that then how many fewer conventional power stations will we need on those nights when there is no wind?

BTW, ask yourself this question. Why haven’t the “green energy” people mentioned the downside effects of wind power? It obviously removes energy from the wind or it would not generate electricity in the first place. That lost energy in therefore no longer available downwind at places where it has naturally existed for eons. Wind power changes the ecology downwind. Why haven’t the greenies been talking about that?

Windmill Farms answers:

The huge oil companies will not allow green energy projects while they can still extract oil from the ground. As far as they are concerned it’s fvck the environment while they can make a fortune killing the planet. For the price of the wars fought in Iraq and Afghanistan every home in the U.S. Could have been fitted with solar panels, thus giving every citizen practically free energy. Unfortunately the people making a fortune out of pollution would never allow such a sensible act.

Uses Of Wind Energy In Daily Life

Ruth asks…

How much will it really cost consumers to use more “alternative” “green” “renawable” energy?

I live in Maine, and the govment is squabbling over whether to make renewable energy a larger part of the states portfolio of energy sources. Our “governor” Lepage and his cronies want to protect us against higher costs, the other side insist that it will save us money. Neither side will come out and give numbers supporting the arguement, I havent even seen any fake off the wall numbers in the so called newspapers like the bangor daily news.
I want to know two things, one is how much will this actually cost or save me, and two why dont they report on these things and tell me. If they mandate 10% more wind and it will cost the average consumer 5 bucks a month for the first year, and then save 2 dollars a month for the rest of time, then why dont they tell me that. Or why doesnt lepage come and say that it will cost everyone in maine 100 dollars a kilowatt hour forever. Why dont the papers actually follow up on things like these?
ps. Id also like to know if there is a better category to put this into
ha, ive seen wind turbines out west, and eyesore isnt my opinion of them, the cell phone towers they have on every hill top in maine on the other hand…..
bb., saying things like that is what Im talking about, for one thing the “back up” arguement is only if there is bad planning and a serious problem with lack of capacity, and you still dont give any actual numbers about expense. We stop subsidizing gas prices to the tune of 5-10 bucks a gallon, it would be expensive too.

Windmill Farms answers:

You need to think long-term when it comes to renewable energy. It’s not just about you and other people alive today. Short-term costs are a distraction. Energy and money are two different things, the former being physical and the latter being a man-made construct to compensate for time and labor. People often abstract everything down to money and forget what’s really making life possible.

Look up “Peak Oil” and EROEI to see why fossil fuels can’t be banked on indefinitely. U.S. Oil production peaked in 1970 at 10 mbpd (about half our current consumption rate). That peak included offshore drilling, Alaska, and shale oil. There is no magic savior and alternatives are badly needed.

Having stated that, I’m aware of plans to expand eyesore wind turbines all over Maine’s scenic ridges, which doesn’t seem very “green” in the larger scheme of things. The human population is too large for simple answers to energy questions. Rural areas in Maine and elsewhere seem slated for sacrifice to distant energy needs.

Which is the best solar power generator for home use?

I want to run my whole house on solar energy permenately, but I don’t know which type of solar power generator is fit for the job, where I live gas power generators are sold based on the kilo watts they out, with those types of generators I know I need atleast a 12 kilo watt generator but I don’t know which is the equvilant of that in solar power generators, I also want know the best brands and prices and the best and most guarnteed website to buy it from online because it’s not availble in my country.

Thank you in advance
okay I forgot to mention that I have a 6kw gas generator for power outage emergencies, and I want to abandon it and the power that government gives altogether and I want to replace them with a solar system, but imagining that I have a 12kw gas generator I want it’s eqivilant of solar system with the power storing and every thing, so to summon the question
Which solar generator that can give the house a consistent 12kw of power? I guess it’s gonna have to store much more than that like 2000kw or something

Tanks again in advance

Windmill Farms answers:

You’re asking for the most expensive solution, a grid free solution.

One reason it’s expensive is because you would need batteries which in themselves are expensive but they are also inefficient, lead acid batteries which are the least expensive per capacity are 95% efficient at discharge but only 50% efficient at charging, they are also not very good at deep discharges though you can buy deep discharge versions, basically even with the deep discharge versions, you lose a lot of battery life if you discharge by more than 20% hence you design the system with five times the daily cycle. Fortunately, the excess capacity would allow you to weather 3 to 4 cloudy days. The low efficiency more than doubles the amount of solar panels required.

Another reason is that the inverter, like your gas generator, must be selected for the expected peak load. An inverter is 95% efficient or higher when the power from it is being used at full load but only 50% efficient when the load is low. On average, with household use, you would expect the efficiency to average 65%. This increases the number of solar panels needed by another 54%.

Between the battery inefficiencies and the inverter inefficiencies, a grid free system has to have 224% of your average power consumption and must do so during the usable hours of sunlight which in the southern US states would be 6 hours, in the northern states, 4 hours, in Alaska 2 hours. Yes, the Sun does shine longer on some days but those are the insolation numbers to use for calculations.

You could economize by using Nickel Iron batteries which can be discharged completely without damaging the batteries and are 80% efficient at discharge but 65% efficient at charging giving an overall efficiency of 52% which is 4.5% higher than that of lead acid batteries. The ability to completely discharge allows you to design to hold just one day’s worth of power instead of five day’s worth but this means you would have to use a backup gas generator on cloudy days. Nickel Iron batteries hold less energy so they would take up more space for the same amount of energy and they are more expensive.

You could also economize by switching to all DC appliances thereby avoiding the need for an inverter. This isn’t too difficult as DC appliances are made for RV’s.

If you calculate how much of your power use will be during the day, you could reduce your calculations slightly as some of that power may come directly from the panels instead of going through the inefficiencies of the batteries. Likewise, adding a wind turbine could reduce the numbers slightly as winds tend to blow at night though you can only expect 1/6 the capacity of a wind turbine as the wind doesn’t always blow at the right speed.

A much better solution would be to use a grid tied system where you sell the power you produce to your utility provider and buy it back when you need it, effectively turning the grid into a 100% efficient battery through accounting. The inverter would then only have to be selected for power production during the insolation hours instead of the peak draw and the inverter would always run at full load when it operates so you get 95% efficiency and without the inefficiencies of the batteries, you only need to cover the average power consumption with the panels. The problem is you need a net metering contract with the utility and they will charge a monthly fee for that and if the grid loses power ( a power outage ) so do you. You would also be affected by any changes in the net metering contract that may happen in the future.

Unless the cost of power from your utility is very high as in greater than 40 cents a kwh, a grid free solar photovoltaic system would not be an economic selection. Even a grid tied system would require government subsidies to be worthwhile.

Wind Energy Jobs

Thomas asks…

Alternate energy = lost jobs?

Here is what I was thinking. It’s possible that companies like Exxon Mobile would receive less profit by the spread of alternate energy therefore causing the loss of 30% of the workforce. So if they employ about 150, 000 workers, that’s 45, 000 lost jobs.

However, if products became cheaper over all, that would boost production of items and also make it cheaper to buy a house, higher manual labor to build houses, make it cheaper to start businesses for those interested and probably just everything is cheaper. Perhaps with the increase of item production, more people in those factories and so forth are required? And carpentry increase because people would be starting more business or making new constructions since those things would be cheaper? Also, an increase in skills and expertise for making components of these magnetic motors? Increase in jobs to keep maintenance around magnetic motors in-case something goes wrong?

Not only that, the electricity bill would be practically nothing. So, if you own a house, you don’t have to pay these bills. Just perhaps water. Water bill may be very cheap as they don’t use gas to pump.

I was looking at the magnetic motor for perpetual motion that doesn’t require a fuel of any sort, just magnets.

Perhaps it would cause job loss but also create other possibilities. With the lack of dependency on oil, we won’t have to worry about the north pole or the south pole melting and drowning half the world. We won’t have to worry about things like cap and trade, taxing our carbon emissions. Also, Our mobility would increase, imagine paying only 50 dollars a flight from here to somewhere across the world. Perhaps a little more.

The mobile industry would see an increase in terms of flight. If flight is cheap, they’d probably be building a lot more aircrafts because it is so cheap to fly, a lot of people would be flying. Thus an increase in the aircraft building and safety job market? The technological job market would probably increase 10 fold.

Basically, the types of jobs I am seeing would increase so far are the technology jobs and the carpentry.

What do you think?

Is it nut-baggish to want alternative sources of energy? If anything, you are nut-baggish for wanting to drill Alaska… Alaska is where all a lot of the ice is… therefore, you’d be creating a lot of ozone gases that would destroy the atmosphere directly above the ice country…. Melting it faster…

Plus possible oil spills up from alaska when they use ships to ship the barrels. Alaska has a lot of resources in fish. You will jack up Alaska.

How much is huge amounts of money and resources? Replacing a gas powered engine or turbine for I’d say 5 electric facilities with a magnetic one would cost less than the supplies needed to higher and drill Alaska. Plus it would cause less impact damage on the environment. Who knows how many fishes and world food supplies would be poisoned due to the drilling.

Also, we wouldn’t risk melting the ice. I’m pretty sure I saw a presidential candidate named Boehner state that he wanted to drill Alaska so it is curious what you say.

Resour

Windmill Farms answers:

The only true solution, as I see it, is to drill in Alaska and cease our dependence on Middle East oil. This Green phenomenon has become a religious cult. I’m sorry to say that, because I have Green friends — but the Green movement followers are simply a nut-bag religious cult.

And one thing that the Green Leftists forget, is that to convert from conventional sources of energy to the newer sources of energy (such as solar and wind) is going to take a HUGE, HUGE amount of money and resources. We don’t quite know what we’ve gotten ourselves into. The Green Leftists are sold on the idea that we can do everything RIGHT NOW, and they don’t take into account the resources and money necessary for their conversions.

James asks…

Why doesn’t the country invest in wind energy? What are some problems with it? ?

I’m looking for a little debate with someone about it.

I know the state of Florida is 33% on wind power, (I know. I’m shocked too and I’m a Floridian)

Windmill Farms answers:

First of all, this country is investing heavily in wind energy. If you don’t believe me just go on a road trip. Wind farms are popping up all over the place.

That being said, wind power is very unreliable. You can’t just turn on a switch and say give me wind power. You need weather to cooperate.

If you are a utility and your job is to meet the power demands of a large population, the most important thing is control. You want to be able to produce the right amount of power at the right time. A grid that relies greatly on wind power is not always able to do this.

For example, consider a heat wave that lasts for a couple weeks. First of all, during a heat wave a normal system is stressed. Everyone turns up their AC and at the same time most power plants loss efficiency and have to drop their production. Now consider that during most heat waves wind speeds drop to almost zero. If your grid relied on wind for 20% of its power, you just lost 20% of your energy production, and your already stressed systems will fail. Now you have rolling blackouts. And rolling blackouts during heat waves kill people.
Not to mention the billions of dollars in lost revenue.

I’m not saying that wind energy is bad, I’m actually a big advocate, but we need to be honest with ourselves and realize that you cannot power the grid with wind alone. Solving the energy problem is going to require using all forms of energy generation to minimize the environmental damage, cost, and risk.

Sandra asks…

How does alternative energy such as wind, solar, hydro, and geothermal take away jobs?

Just please explain how

Windmill Farms answers:

It is similar to the way that a policeman takes away the job of a thief that they catch.

Fossil fuels have been releasing solar energy stored over millions of years for our use. They are a very condensed form of solar energy. But along with the solar energy chemical compounds were also stored over millions of years. Those compounds have been being dumped into our common atmosphere. The price for that solar energy seemed very cheap but we have also been paying in loss of life and health for our deteriorating atmosphere.

Many people are employed in the coal, oil and gas industries. Some have been getting extremely rich as wealth is transferred from the dead and dying to the wealthy. Many more people will be employed in alternative fuel industries. It may not be the same people who get so wealthy. Some jobs may require far fewer people but there will be other jobs that will require far more people.

To say jobs will be lost is like looking into the pail we just emptied before we begin to fill it again.

Linda asks…

why do we not build wind turbines all over the country,lower energy cost many jobs to build them?

Windmill Farms answers:

There are several problems starting with the lack of sufficient wind in many locations. The second problem is the old “no in my back yard” situation. There are many people who do not want large wind turbines in their area. The classic example of this is the Kennedy family at Martha’s Vineyard.

Next, I am not sure the electricity from wind turbines is actually cheaper than fossil fuel fired power plants. This is specially true when you add in the cost of new electrical grid extensions to reach the areas where wind farms will work.

As to many new jobs, you will find that many of the new jobs will go to China or other countries where they can build a wind turbine cheaper than here in the US.

Windmill Farms answers:

The renewable energy sources you list do not pollute the environment anywhere near the extent of a non-renewable source like coal. Coal, even with newer clean-burning technology, still leaves a very large carbon footprint.

Chris asks…

where do fuel cells rank with other renewable energy source?

A list of like the top energy sources with fuel cells would be really great.

Windmill Farms answers:

O.k. I’m going to reword your question and then try to answer it. How do fuel cells fit into our energy needs.

#0 Increased energy efficiency (will do more to help than any alternative “source” of energy”

#1 Coal Where most of our electricity comes from (Cheap, but dirty, lots of it though right here in the U.S.

#2 Oil/Gas Where heating, transportation, and some of our electricity comes from. (A little pricey, supplies might be running low, at least where we can get them easily, range from very clean to filthy.

#3 Nuclear. Where a lot of or electricity comes from. (What to do with radioactive waste?, Security issues? Safety? Expensive compared to coal, mostly because of regulations, but no greenhouse gas emissions)

#4 Hydroelectricity (Clean, cheap, Dams create environmental problems, displace people, only feasible in certain areas.)

#5 Wood (Not typically used to create electricity but renewable, used to heat homes, cheap, dirty and high labor.)

We now enter “alternative energy”

#6. Wind, (similar issues to hydro, but less output. And can’t be stored.)

#7. Solar (Very expensive, requires battery banks, widely used in remote locations and specialty applications.)

#8 Batteries. (Great for flashlights, everyone waiting for the breakthrough in high capacity inexpensive battery. Not here yet, may never be.)

#9 Fuel Cells. (Expensive, but may hold promise, could make a GREAT alternative to batteries to run flashlights, cell phones, cars, homes?)

#10 Get a horse (Expensive, slow, no place to plug in my i-phone)

#11 Dogs on treadmills.

Robert asks…

list 4 benefits of using your energy resource?(biomass)?

Windmill Farms answers:

1) Sustainable: renewable energy source
2) Energy recovery: removal of wastes from waste streams (waste biomass only)
3) Climate: reduction of emissions of CO2, CO, SOx, NOx, PM10 and VOs
4) Economics: synergistic use of an otherwise wasted resource
5) Fuel independence: reduction of reliance on fossil fuels
6) Carbon neutral: carbon locked-up in biomass is released as small amounts of CO2, water and energy

Mandy asks…

ReNEWABLE ENERGY BASICS?

wHAT ARE THE DEF. OF SOLAR,HYDROPOWER,WIND, GEOTHERMAL AND BIOMASS ENERGY?WHAT R SOME EXAMPLES,ADVANTAGES AND DISADVANTAGES OF THESE ENERGYS.
LIST THOSE ENERGY SOURCES THAT R FOSSIL FUELS,WHAT MAIN ADVANTAGES DO FOSSIL FUELS HAVE OVER THE RENEWABLE ENERGY RESOURCES,WHAT R 2 MAIN DISADVANTAGES OF FOSSIL FUELS COMPARED TO RENEWABLE ENERGY?

Windmill Farms answers:

Next time turn Caps Lock off please. :-(

Solar Energy-Energy from the sun-solar power is renewable- costly to install

Hydropower-Energy produced by falling water inespensive, water is renewable, and produces little pollution-destroys forests an wildlife

Wind Energy-Energy produced by the wind-renewable, windmills take up little space-only certain places have enough wind

Geothermal Energy-energy from heat in the Earth’s crust-produces little pollution-only possible in a few places

Biomass-organic matter that contains stored energy-plant material can be changed into liquid fuel-needs a lot of land

Fossil Fuels(these are just a few)-petroleum, natrual gas, coal

James asks…

energy sources in terms of their relative use in the US?

could somebody list folllowing energy sources in order?(the most used first)
nuclear, wind, hydropower, geothermal, solar, biomass, coal, natural gas, and oil.
