Re: Chevy Volt justification
said by TheTechGuru:That's the Volt drive train, its 100% electric ( aka serial Hybrid ) from the battery, the gas engine drives a generator.
Something I'd consider if someone made one is a Diesel-Electric (like a train). Diesel engine turns generator only and unlike a Hybrid is not connected to the drive train.
On the Fuel Cell, it will never match the efficiency of battery electric as you have to somehow create the Hydrogen which isn't a fuel at all, its a carrier of energy and you have to make it somehow.
As for efficiency creating hydrogen to then use a fuel cell is less than half as efficient as just using a battery which already will provide electricity back without the need for a fuel cell.
