What you're describing is not possible. In order to get electrical power from the rear wheels, they have to be spun by the friction from the road. Assuming no efficiency loss anywhere in the process, the best possible case is breaking even. What you suggest is a variation on the perpetual motion concept.Perpetual energy would imply that generation:consumption would be 1:1. I've built into my calculations the fact that you won't be able to replace all of the power you use, driving down the road (theoretically, the ratio would be .75:1).
We all know that adding accessories to an ICE robs the ICE of power. Yes, it makes sense that adding a generator to the rear wheels of an EV will reduce it's range. BUT, it will not reduce the range to 0. And, the generator will compensate for the loss, while at the same time extending the range.
The way I see it, rather than just writing the idea off, why couldn't somebody do some research, and figure out how much power the generator would rob, and how to compensate for the lost power?
