work on a tank of fuel being a couple of hundred kwh in electrical
terms. 200kwh in 1/60th of an hours is 12MW.

So about 13,000 amps at 240V..

Of course the supercap is only enough to get you five miles.. so
probably about 130 amps

realistically it should be possible to supply those sorts of peak loads
at 'filling stations' but it wont be easy..or cheap.


But if the recharge station itself has mega-super-caps that it charges
up relatively slowly, then the delivery of power to the charging station
might be very achievable.

(Can't help thinking that filling stations canopies represent a huge
area desperate to be populated by solar cells. Though being built
next-door to nuclear power stations would be more likely to fulfill the
electricity requirement.)
