The hurdle to this kind of fast charging isn't the tech in the car nor is it the tech in the charger. It's powering the fucking things.

Agreed.

would require a nuclear reactor sitting out back to supply the required 1.2 Megawatts of power!

Eh....

At 5 minutes a car, each charger would be able to accommodate 12 cars per hour. The 12-charger station, fed by that nuclear reactor, would be able to handle 144 per hour.

A typical gas station that size has an 8500 gallon tank, and refills 2-5 times per week. That amount of fuel will serve somewhere between 1000 to 3000 cars per week, or about 6 to 18 cars per hour.

This doesn't call for a nuclear reactor at the station. This calls for a sufficiently large battery pack at each station that can "trickle" charge continuously. I say "trickle" - if I did my math right, it would be about as much power as 15 hot tubs or 60 water heaters. About as much as a grocery store, with all its freezers, refrigerators, lights, HVAC, etc.
