GG I think you have got the wrong idea. My point was simply that the efficiency reward from recapturing the braking energy is tiny compared with the total energy used in drag, rolling friction and air condtioning if cars are operating in level lands. Eric raised regenerative braking supercapacitors as being proof that they are not just science fiction. But being good in buses and mountains is not what we were discussing which was the comparison of battery swapping with parked recharging. Pointing out that going up a mountain then down again would make regenerative braking worthwhile doesn't mean it's worthwhile for flat-landers. But I was surprised how much super capacitors are in use in special applications. Having them big enough to provide all the energy for a car is a lot different from a small one to capture braking energy [5% of total energy used in an electric car I guess]. Yes, it would be nice if Qualcomm, which is allegedly a monopoly, would be able to actually profit from the most important invention in human history. Being robbed by China, Korea and the Euroserfs is very annoying. Mqurice
