EV charging and hydro generation/distribution challenges

[tomh009]

My comment was do non-hybrid EV's "recharge themselves" to supplement  the plug in, not replacing it... I realize perpetual motion isn't a thing.

My thoughts were more of a plug in and charge for 1/2 hr as opposed to a 3 hr charge if the battery wasn't drained over the course of a trip because it was regenerated by braking, wheel turning etc.

Regenerative braking is how non-plugins charge. And, yes, plug-ins and BEVs do the same, it's just less significant given the much larger batteries.

Charging from normal wheel motion would be counterproductive as it would increase the energy required for keeping the car in motion.
