Q: Wind Power?
Wind Energy?
“950W of power at 45km.hr winds
Delivers 100 Kw / hours a month at an average wind speed of 5.4 m/s
Adjustable voltage (12/24/36/48V)”

Can someone please tell me what that means? And my question is would you be able to indefinitely power a small fridge, a TV and other things on that wind turbine which costs $3 000? I’m posting this many times because I’m not satisfied with the answers I already received. People are just not making it simple enough to comprehend. Its all spanish to me.

A: What all the technical detail boils down to, is that the system will deliver a limited quantity of low voltage lighting. Say enough for outside area and security lighting is about it.

Q: wind power?
what are the positives of wind power?
i have got so far that
off shore takes up no land
it can provide 10% of UK’s electricity
it is renewable
and it doesnt cause and pollution

A: Many positive however they kill birds who fly into them and can block out radar systems acording to the Minesrty Of Defence.

Q: Wind power?
I had a thought and wonder if this would work. If you had an 8 inch pipe and it funneled to a 1/2 pipe would it produse more enegry than the average wind mills. I know I am reaching here but it is basically how a jet engine works.

any tips or suggestions?

A: Yes, the velocity of the air would increase, no doubt about that!

However, along with that velocity increase comes a proportional decrease in the cross-sectional area (8″ down to 1/2″), and therefore the net result would be the same amount of “work energy”, minus the losses due to turbulence and friction in the process of narrowing down the air stream.

But keep on trying – you never know, you might hit on a great idea that will save the world!

Q: Is wind power generator at home really work ?
I heard about wind power generator and I want to make a wind power generator to power things in my house. Although I am not sure where to find good information. I want to save money. Is there any reliable information on how to make wind power generator at home?

A: I made mine wind power generator and its saving me some good money :) I use it to power various things inside and outside my house. I found the best source of info for this at:

Good luck :-)

Q: How to make a wind power generator at home?
I want to make a wind power generator to power things in my house. I want it to be able to power a small tv and DVD player.

A: To make this you will need a few things.
the generator, blades battery and inverter.

I have made three of them and I use them to power various things outside like lighting, pool pump and tv.

The best source of info for this is http://www.earth4energy.com. Thats where I got my blade designs from and learnt how to wire it up.. Its saving me some good money :)

Q: How do I make my own wind power generators?
I want to make my own wind power generator at home because I want to use it to power my laptop and a small portable TV. How do I go about building wind power generators?

A: I make my 2 wind power generators at home and you will need
a generator, blades battery and inverter.

I use them to power my lighting along my balcony.

Actually I got the infomation from http://www.makewindpowerathome.com. Thats where I got my blade designs from and learnt how to wire it up.. Its saving me some good money :)

Q: What tax advantages are there for using wind power and what speeds are required?
Are there U.S. federal tax advantages or rebates for using wind power? Does Illinois have tax advantages or rebates for using wind power? What are the required average wind speeds for Chicago and other areas to successfully use wind power?

A: 9MPH for sustainable electricity generation.(low wattage production at that speed) US government currently offers tax incentives for eco-friendly conversions like wind generation or solar power. however last I knew there was a cap of 2000 dollars. As a republican can I just say Thanks for nuttin George. I’ve got your rebate right here! Some lenders have special programs to help you set up a system with lower interest rates you may want to see if there are any “Green” credit unions or co-ops that lend. Join one and go from there

Q: How does wind power relate to life science?
I have a science fair coming up and I need to know how wind power relate to life science.

A: wind is related to life science because wind power creates energy and energy is what makes the world work now days. Also the wind helps life by moving spores which come from some plants, and if the spores fly then land it will grow a new plant life. also oxygen and wind to keep us cool when it is humid or hot. wind helps nature, human kind, animals and different types of life. so i guess since it helps life it’s a part of life. oh! a clouds too.
P.S. i at least sould get some credit if you us this info.

Q: When is wind power expected to be easily accessible to the general public?
What is keeping wind power from widespread use and when is it expected to be easily accessible to the general public?

A: The last time you had a choice to pick your source of electric power, you may have had a choice for wind power produced electricity at about a 1-1.5 cent per Kw of electricity premium.Otherwise called “green”, it is on the grid. It is generally more expensive than traditional power but it is improving.Estimates are that wind power could produce 20-30% of the grid power by 2030. The Bush years saw a reduction or elimination of tax credits for green power. The Obama years may see an incentive which would raise the expectations because of tax relief or incentives. After all, Connie Rice had a vested interest in big oil but Obama doesn’t seem to.

Q: What does wind power have to do with sustainability?
I am doing a science project and I am completely confused. I have no clue what sustainability means and how it connects to wind power. Any help I would appreciate.

A: sustainability is the idea that resources should be able to be regrown or regenerate, not run out. oil- not sustainable. corn- sustainable.

wind will never run out is not used up and can be used with no harmful effects on the environment.

Q: What are the pros and cons of using wind power to power up our community?
It’s for a project.
What are the pros and cons of using wind power?

A: Pros:
Cheaper electricity
Windturbines require little maintenance
Whoever owns the land where the windturbines are installed get a TAX BREAK
Windturbines don’t spew out any pollutants

Cons:
Some people think windturbines are ugly
If you stand right under them, it’s noisy (but far away you don’t hear them)
Location has to be windy most of the time for them to work
They are very tall (I don’t think it matters so much)

I think the pros overweigh the cons ANYWAY
I’ve seen windturbines from a distance and I think they look rather nice!

Q: Is it possible to do build a wind power generator to turn a small electric motor?
The quoted question is:

Build a wind power generator that will turn a small electric motor out of everyday items if possible.

N.B. You cannot use anything that is typically found in a science lab.

A: Yes, absolutely. What’s more, it’s actually quite easy. You won’t get significant amounts of power out of it but it will run a very small electric motor so long as you use a generator that is significantly larger than the motor you are driving.

You’ll need something that you can use for windmill blades and a motor that you can drive as a generator.

The best and easiest solution is to use a radiator fan from a modern car. Most modern cars use electrically powered fans and this is perfect for you because it takes care of the fan assembly and the generator in one go without the need for a complex assembly procedure. They are cheap and easy to get hold of too. Any car wreckers should be able to sell you one for under $20.

This type of fan is not the ideal configuration for capturing wind (they are designed to generate airflow from electricity, not electricity from airflow) but the advantages you get from simplifying the construction process more than makes up for this. Also, as far as I am aware, they are all DC motors which is exactly what you need.

Because a generator is identical in construction to a motor, this fan will generate electricity for you without any need for modification. All you have to do us hook up your small hobby motor to the terminals of the fan motor and put it somewhere where there is enough wind to get the fan spinning. You should be able to generate up to 12v depending on how fast you can get it spinning. If you find that it takes more airflow than you can manage to get it spinning fast enough, you can always construct a ram scoop (like a big funnel with the wide end open and facing the incoming wind and the fan across the narrow end) so that the wind is scooped in from a wider area and forced through the fan at higher speed. This doesn’t need to be that strong, corrugated cardboard (like you get from cardboard boxes) would probably do the trick.

So long as you get the fan spinning at a reasonable rate, you should be able to easily power a small motor. Of course, as soon as the fan slows or stops, so does the motor so it’s not really a viable solution for real world applications. It should be fine as a simple experiment to demonstrate wind power though.

If you want it to be a bit more practical (i.e. actually work in the real world rather than it just be for demonstration purposes), it would probably be better to run the motor from a battery and use the generator to recharge the battery. This is how proper wind powered systems work. However, the setup becomes more complex when you do this and some circuitry is required to manage the recharging of the battery, among other things, so unless you have some experience with electronics, I wouldn’t advise it.

It sounds like this is outside of the parameters of your experiment anyway.

The motor you are going to drive should, ideally, be able to run on voltages between about 3VDC and 12VDC but cheap and easy to find motors like this one (http://www.jaycar.com.au/ShowLargephoto.asp?id=3255&IMAGE=) that is designed to run on voltages from 3V to 4.5VDC will still probably work OK for your purposes. If it is fed 12V continuously for long periods of time, it may overheat and burn out but, considering your setup, it will probably last at least long enough to meet your needs. If you do go for a low voltage motor like this and you want to make sure you don’t damage it, just make sure that you don’t spin the fan too fast and monitor the temperature of the motor. If it starts getting hot (i.e. too hot to touch), stop it and let it cool down for a while before you start it again. It’s not too big a deal if you do burn it out though, these motors retail for about $2 so you won’t exactly go broke if you kill it.

Good luck with it.

Hope this helps.

Q: What major companies use wind power as one of their sourses of electricity?
I have a class that i need to list some companies that use wind power as their source on energy. So if you know or, think that you work uses wind, or if you know what does use wind please post the companies name[s]!
-Thanks Via

A: p.g.e
portland general electric
and try naming some fromtexas theres alot there

Q: Is overall wind power a positive or negative impact on the environment?
I know that there are many advantages but also disadvantages of wind power, but overall would it help our environment?

A: Wind power is having a positive impact, at this point, on manufacturing, and definitley on employment. In the country, farmers/ranchers are enjoying monthly/yearly income with the installation of these wind generators on their properrty. A good thing. Power transmission lines need to be installed to get the power distributed to wherre it can be consumed, again providing job opportunities. One bit of concern, are migrating birds, such as ducks, geese, an cranes going to be decimated in numbers if they fly into the rotating blades, possibly. It will take years and years of construction of wind generated power to fulfill our needs at current levels of power consumption. Therefore, coal, water, natural gas, and nuclear will continue to dominate the power scene.

Q: What are the benefits of wind power compared to nuclear energy?
What are the benefits of wind power compared to nuclear energy and which countries already use wind power?

A: Wind power- no chance of meltdown; less people to manage; no waster
Nuclear- more power; more efficient; more reliable; better overall
Not sure about the countries
