This Maglev Wind Turbine Powers 750 Thousand Homes. Thats right, 750000. Thats more than one entire power station. One of these wind turbines requires less than 100 acres.
The figure given is under optimum wind conditions. The turbine uses maglev bearings for zero friction. It uses similar technology to the maglev trains in Japan.
Several of these in a high wind area like of the coast of Florida would produce a lot of energy.
Some people have commented that it would weigh a lot because it is the size of a building. Well if you made the vanes from a low weight material like thin fibreglass or something similar it wouldn't be a problem.
Other people say it would kill a lot of birds, well not if you built a frame around it and covered it in some kind of net.
The American company that designed it have working turbines and there is one being built in China.
