many people are making there own wind turbines to generate small amounts of power, say enough to run the tele or shed lights, there are many home made ones ive seen on the net. some made from old motor bike wheels and washing machine motors to more elaborate designs that work really well, for what they are.
funny thing is an electrician mate once said to me that if they made minature nuclear reactors, he was talking about the size of a large house sized stereo speaker, they could generate enough power to supply around 15 houses and due to the size any problems with them would be very minor, and that because they are small they can be made more safe.
i dont knoiw but if they can be made as good as he was saying then it could actually be a safe alternative?
