A multi-phase AC motor can be upwards of 90% efficient (which I believe you mean to say instead of "effective") . And usually at least 80% these days. 30% would be more typical for a pre-1970s DC motor.
On the other hand, a gas motor loses around 60% of energy to heat (not considering braking). -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
