Coming to a Rooftop Near You: Maglev Wind Turbines
Sep 17, 2009, News Report
Found in: Emerging Technology & Innovation
Vertical wind turbines put pressure on bearings, but one company, Enviro Energies, has a better idea: maglev or magnetic levitation of the turbine so that it will turn, not on bearings that need lubrication and servicing, but on a virtually frictionless force field of magnetism. In addition, Enviro sees its new vertical turbine as suitable for city rooftops, as its design takes even light wind currents from any direction and converts them to usable electrical power. See a Discovery Channel demonstration of how the turbines work.

This is amazing. I would like to incorperate this with my PV array to make a hybrid electrical system for my house. It would complete my electrical needs for my bike, geothermal heating system and electric hot water. I just don't know if there is enough wind to make it doable. The DOE wind maps are over 20 years old. Where do I start?
