[Gasification] ...a question about hybrids

Hi Max, et al

I meant a separate alternator coupled to the trailer axle which could be 
controlled by a load cell attached to the trailer hitch. When it sees a 
load, it assists in slowing the vehicle down by increasing field 
excitation and converts mechanical energy back to electrical energy.

Re: Harmon's bus + trailer

I don't see a difference. He would just need longer cables to get 
electrical power to the electric motor (presumably at the front of the 
bus). If it's big, like a school bus, the motor controls might need to 
be a little more sophisticated and of course, the wire gage and 
batteries would be scaled up as well. When all is said and done, I'm not 
sure an arrangement that size would be cost effective.

...then again, this is all speculation - isn't it?
