Yeah, I've seen that video. Very cool indeed. But it doesn't simulate the mechanical conversion of wind power to prop shaft power. I would really like to see data from the thing on an operating turbine to see how well it can keep the blades near their optimal TSR (i.e. out of stall). So, data that includes wind speed, RPM, volts and amps out of the turbine and volts and amps into the batteries would be the tale of the tape, so to speak. Actually, come to think of it, I imagine the system may be able to tell us what, in fact, the optimal TSR is of any given set of blades. anyhow, real-world data would be GREAT! But, until the kinks are ironed out, they may just be keeping a lid on the data.... Anyhow, thanks for the link.
