There is no way in the world an AC motor the size of an alternator will turn over an engine without severly high voltage, so no, I'm not talking about his original idea of converting his alternator to also pull the engine.

Brucey's project can be a success due to hilly terrain in part; being able to stay in overdrive while climbing hills by powering up the electric motor, helping by being a starter motor for constant restart cycles, and helping on the downhills with additional engine braking. I know where I live is similarily hilly, and I always lose 1 mpg trip average just by climbing the last 1/4 mile hill to my house, and other than a project like Brucey's, there is nothing I can do about it. Also, with him having an auto, he could "idle" the engine with the gas turned off for extra long coasts.
