An old idea given new hope?

[beedees]

1hp = 0.7456kW
1kW = 1.341hp

and electric generators are about 90-95% efficient, so 1hp on a 90% eff. generator would make 671.04 Watts.

Thanks for the info, but how do you figure what is needed to produce a certain amp. at a given voltage. Iam NOT an electrican, just a crazy old man with some ideas.

its really not difficult: P=U*I   --> (Watt) = (Voltage) * (Ampere)
You can transform this like : I = P/U  or U = P / I

0.7456kW = 745,6 Watt = 1PS     --> 1Watt = 0,0013412.. PS


so if you have for example 12v and need 5Amps --> 12*5=60W => 60*0,0013412 = 0,08047PS
