With the world’s ever-increasing demand of power being more than its supply, it is about time that we take concrete steps to save power. Apart from being conscious about the usage of power and water at home, one can employ pollution-free and cost-effective power solutions at our homes. Solar power solutions and wind power solutions are the two of the most efficient solutions that can replace the conventional power solutions employed at our homes.

These solutions can help you combat power outages, reduce your electricity bills, and also help the environment.

variable pitch blades varied by governor

please help me! i can’t figure this out.

You can look it up.

GE’s turbines, which are common in the U.S. have a max output of 1.5 mega watts (1,500 kW). Actual output is dependent on location and local weather.

I want to use a small windmill, about 1 to one and a half feet in diameter, spin it in the wind, have it produce 12 volts of electricity, run the electricity to a power inverter, then I can plug whatever into the power inverter. Or could i hook something else up to produce electricity to go to the power inverter? something simple? Im working within a small space. thanks for your help.

It is difficult to answer your question as you have not indicated what you want to run on the output of the generator that is driven by the windmill. Were you wanting to run a television set, you could not as the voltage would be too poorly regulated in most circumstance and were you wanting to run a pizza oven, the output of the system you have described, would be insufficient. With a windmill that is 1.5 feet in diameter, only a very small alternator could be driven. In such a case, you could use the alternator to charge a battery which could in turn supply a UPS unit that supplies the television set. The most common option to a windmill is a photovoltaic array but they are very expensive. Reply and say what you actually want to achieve and people will be more able to give you precise information.

Please recycle. Thank you.

Vote Gore 2012

HELL NO!!!!!!!!!!!!!!!!!!!!!!

Government has no right to force us to do anything, including buying government sanctioned health care.

I would love to see Gore run in 2012. That would be an easy victory for the republican.

I have to build a HOMEMADE windmill for an English project and I have no idea how to approach this project. Any ideas?

Easiest way is to use a car alternator.

I love the idea of offshore windmills BUT….

Sharks depend on a receptors that are tuned to sense electic fields to hunt prey.

Hopefully the cables are properly insulated and will not cause stray electric fields. I doubt that a shark would mind too much anyway. they will just hunt somewhere else.

No. Your washing machine AC motor does not act as a generator. You can however use a car alternator and batteries for storage. Connect this to an inverter for AC power. I helped a friend build one to provide power in a large shed/ workshop.

1. The power P delivered by a windmill whose blades sweep in a circle of diameter D by a wind of speed v is proportional to the square of the diameter and the cube of the wind speed. This dependence on diameter and wind speed is expected in the case of 100%-efficient energy transfer from the wind to the mill. Show that for 100%-efficient energy transfer the power of the windmill is given by P=(pi/8)*ρ*D^2v^3 .
(Hint: First calculate the kinetic energy of a cylinder of air of density ρ moving with speed v, then determine the rate at which this energy is transferred to the windmill.)

The answer is pretty much embedded in the question and the hint.
KE(cyl) = mv^2/2 = ρ*Vol*v^2/2 = ρ*πD^2/4*L*v^2/2
Power = dKE(cyl)/dt = ρ*dVol/dt*v^2/2 = ρ*πD^2/4*v*v^2/2 = π/8*ρ*D^2*v^3.

just moved to hill with good wind ..looking for one of those windmills(that produces power ) you put up in your backyard and hook it in to power company grid …anyone know of any good sites to find one?

So you got about 5 million to invest , thats what one cost that will supply you and feed the grid also……….Nuf Said
