I actually like this approach to the electric car far better than GM/Toyotas. Makes far more sense...but as cool as your fiends car is as a project (and it definitely is cool!) it still suffers the same issues of lost energy in the conversion of electricity. Not as much as the big boys experiment in futility, granted. But Thermodynamics will not be denied, much as we wish it could be.
Yeah..
We haven't been able to build a decent perpetual motion engine since that Second Law was passed...
