Hard to beliese it can be usefull...
I couldn't here the audio portion.I'll try Saturday.
*I'd like to know it's mechanical efficiency,compared to state-of-the-art turbines.
*I'd like to know it's dynamic stability atop a tower at maximum operational wind speed.
*I'd like to know it's downwind turbulence profile,considering other units operating in its wake.
*The dish itself would have a free air drag coefficient of around Cd 1.35,one of the 'dirtiest' of known shapes.
*And its combined cyclic wake could induce resonant tower oscillations which could potentially bring the whole thing down.
