ReVair Maintenance Free Wind Turbine

This design is blowing my mind! A Vertical wind turbine that spins without friction on magnets.

"ReVair turbines are constructed with very few parts: Base rings, stall rings, five blades, framework, imbedded magnetic bearings, and our proprietary amplified flux field motor.  The assembled unit is compressed between magnetic fields allowing it to levitate and rotate within the magnetic fields. This magnetic bearing feature provides for reduced friction and silent rotation of the turbine even at higher revolutions. The turbine starts up with little wind, and the design eliminates wear
Typical wind mills operate using a complicated gearing system. Mill type generating systems require extensive maintenance, creating  higher operating costs. Experts predict that traditional windmill units will need to be rebuilt or replaced every 10 to 20 years."
Now how much for the 3kw version?
