The article says nothing about the storage capacity of whatever type battery/capacitor is used in the car.
One of the current Teslas claims a battery capacity of 200 kwh.
Charging a 200 kwh battery/capacitor in one minute requires a power of 60 x 200 kw.
12 megawatts.
Nominally, the power consumed by TWELVE THOUSAND houses.
Where’s the generating capacity for that going to come from?
