Darin had a good idea for a forum for all the things that get talked about but no one ever does... The regen alternator should probably be #1

(OK. Just found some who have but I'd hardly call it braking)

This idea has many issues to overcome and the losses are large. If you use an alternator you won't get much breaking at all 100A at 14.5 volts is pretty low 1450 watts. In the Prius, a light breaking event pushes 6000 watts into the batteries. Max regen is 18000 watts! And you would need more than a couple of batteries to take that kind of current never mind the generator. Alternators are 50% efficient at best then there's the losses to produce the hohoh. It would be better and much less lossy to just use the energy to run the overall electrical load.

Sorry but physics is a tough mistress.

I'm not one to be a naysayer, generally as I have done some whacky stuff to gain marginal results but it seems like there is a lot of low hanging fruit to grab before this idea was worth trying. Plus the numbers don't look good.
