I will be building this from scratch, no subsidies, only my money risked. I have solved the overspeed speed shut down. I have solved the stalling. My off grid (once I pull the meter) house, will have over 21,000 watts of 24 volt battery storage (I have over 7,000 watts already, more to come) that will be charged from a combination of solar, and wind for now. With 2 other research generation methods I will look at after I am caught up a little more.
The tip speed ratio can go as high as six, but is a lot more stable at four to one; so at 25 MPH wind speed, the generators will be spinning at 100 MPH I have located a non cogging 24 volt generator for this assembly to turn, and I already have a 3000 watt dump resistor in case of overcharge. The first wind generator I will put up is a 1700 watt unit that will yield between 450 and 500 watts with our average wind speed.
ah...well that's a horse of a different color.
wind (and solar, and small hydro) is a different thing when it's at the 'point of use' level, self funded and with adequate storage.
My concerns were government funded and utililty level.
This design is an order of magnitude leap past the existing wind generator designs (that is why Sandia Labs wants it). It will start at lower wind velocities, and generate about 300% more power. Mine will be a test prototype, to allow me to be totally certain of efficiencies, and control systems, before I patent it.
