...heat from braking. Regenerative braking converts the kinetic energy of the moving car directly into electricity using a generator. The energy is never heat in the process. The brakes work the same way a power turbine does when it converts the kinetic energy of moving water into electricity at Hoover Dam. Normal car brakes do convert kinetic energy into heat. And hybrid cars do have a set of normal brakes for use when necessary. But the heat created that way is dispersed into the atmosphere, not converted into electricity.

And if their fans adore them, well, that seems like a good thing...
