vertical axis wind (and solar) turbine [RE-wrenches]

[Matt Tritt]

Oh boy. Guys, you will notice that neither of these architectural 
statements have a published power curve. First warning sign. The Blue 
Thingy is a twisted Savonius; not an efficient wind turbine at best and 
basically worthless in low winds, but the idea of covering it with PV 
seems so - so - words fail me. Lame maybe? Their product comparison 
chart is full of inaccuracies and/or bad information as well, so I would 
give this beauty the coveted Blatantly Seeking Investors award.

The Quiet Revolution machine, though (obviously) claiming to be quiet, 
publishes no actual dB measurements of the turbine. It is most likely 
extremely expensive, and the individual parts would also appear to be 
big and/or long enough to cost a fortune to ship to this side of the US 
(West). To the best of my knowledge, you just can't beat a good HAWT for 
efficiency, cost effectiveness and net energy production (even if they 
aren't so sexy).
