I think I remember seeing something about the pma's at hydrogenappliances.com on here a while back. In particular, I though someone had stated how to figure out power requirements (turning) versus output into a real load.
The stated power curves are open circuit voltage and short circuit amps. hydrogenappliances.com/pmacurves.html
There has to be a way to figure the output of these in real and useable terms.
I have seen where many people have a sort of distrust for these folks. I have tried conversing with these folks via email and have found them to be generally evasive about efficiency, input vs. output figures, and real world situations. They won't even supply separate rpm/voltage and rpm/amps curves or any power input to power specific load requirements, won't give coil resistances/wire sizes or anything else.
If their stated outputs were correct in relation to the hp input, they would have a "perpetual motion" generator system in some cases. We all know that with the inherent lossesdue to efficiency, this isn't going to happen. If you could really get 20000 watts out for an input of 6000 watts...I'll buy several!
Any comments, suggestions, formulae would be very much appreciated.
Thanks
