3kW 17-foot Wind generator, and you build it yourself!

Otherpower.com's latest project

3kW+ output, 48VDC, 17-foot diameter wind turbine built from scratch. Low winds don't have much power available in them. The only way to harvest a useful amount of energy from low winds is to sweep a large area with the wind generator blades. This turbine charges a 48V battery bank in 5 MPH winds, is making 400 Watts at 10 MPH, and 1500 Watts in a 16 MPH wind. When fully furled, this machine produces maximum power of 3800 Watts. The tail folds up and in during high winds, yawing the machine at an angle to the wind to reduce the massive, exponential, power input increase from high winds. The machine has survived 60+ MPH winds in operation.
