Current claim on the website is 720 Watts at 14 Mile per hour wind. I'd have a hard time believing anything over 250 Watts for a small scale 65" turbine. The reason is that, if my calculations are correct, there is only an amount of about about 674 Watts of kinetic energy available in a 65" diameter column of air at sea level at zero degrees celsius for that wind speed. If the overall efficiency at that wind speed was a generous 35% as power into the grid, then that would be about 236 Watts. Less for warmer air and higher altitude. As Rossw pointed out it was previously more than an order of magnitude out. It is now within 10% of the total kinetic energy available, although it is still at least 80% more than what has ever been found to be possible to accomplish as far as converting that energy to electricity.
Gerryd, I would seriously wait until the testing is done at the independent lab before posting definitive power claims, especially if I did not have an extremely precise way to measure the wind speed. Since the power available is a function of the cube of the wind speed, a relatively small under measurement there could result in generation of a rather inflated power curve. For example, if the wind speed was actually 15 miles per hour instead of 14, you would have about 23% more power available in the wind to start with, it still would not make 720 Watts make sense, but maybe your measurements were even less exact.
