Another "Pie-In-The-Sky" wind turbine? [RE-wrenches]

[Matt Tritt]

<x-flowed>


Dan,

All Betz are off! ;-)

In comparison, if I use the output from the Kestrel e300i, which is 300 
cm in diameter (approx 10'), and is one of the most efficient small 
turbines I know of, the output at 16 MPH is about 500 Watts @ 48 volts 
nominal, slightly higher in high voltage format. This is an averaged 
output using a Weibul distribution, by the way. I think that's pretty good.

The guy who makes these sounds to be in at least his 70's, maybe even 
80's. I doubt that he is an actual intentional fraud, just someone who 
doesn't have a clue.
