Is there any reasonable way to put some kind of a black box between the incoming power and the outgoing (to the car's battery) power that would change from a low(er) voltage/power to a higher voltage/power? I'm thinking of something like a super-capacitor, but the critical spec would be to allow efficient power input at low voltage, low current, and long time, but be able to discharge that black box at high voltage/ high current and short(er) time. Possibly a kinetic energy wheel, or maybe a Hydrogen/oxygen fuel cell.
The idea would be to allow either a PV cell array, or wind generator (that might not work continuously), or maybe just a regular household current from older, less capable wiring, to charge the black box. This could be done while the car is elsewhere. Then, when the car is available and needing a charge, to extract the power from the black box at high(er) speed.
If this were possible, AND it was reasonable to fuel it from a self-generated source (PV or wind or ?) then you might not care if there were extra efficiency losses in the conversion inside the black box. I know it would take a very large array to charge a car battery directly, but if you could buffer the array, would it work?
Next impossible question: make all this work in Seattle, where it's cloudy all winter.
