[Gasification] ...a question about hybrids

[gasman]

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.



¤¤¤ If this wheel-driven alternator is used only to

produce battery charge current at braking, it is VERY

uneconomical and inefficient, compared to the added

weight. If it functioned as a motor as well, keeping

the drag-force near zero it could be defendable.

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?

Mike

"And I was talking about Harmon's Bus + trailer!"



Pointed back on my first mail in this thread,

commenting the woodgas system on the bus

and trailer, driven directly by woodgas using

the bus's original motor!
