Re:1.2 Megawatts (Score 1)

$9 of electricity is about 100 KWh at national average rates. Passing that in 9 minutes gives you an average rate of 1.2 megawatts. What the hell knid of household has the circuit to handle that?

You could buy a device (e.g. another capacitor) that would sit in your garage and trickle charge all day over your existing power lines. Then the device quick-charges your battery when you plug it in to your car over thicker cable.
