What is this story about Toshiba developing a battery giving cars a duration of 200 miles, recharged in 6mins? True or krap?
Would this be possible with a row of 240volt sockets at the local pumps?
Scratching head... Many unknowns... bit of assumption here and there.

Drive 200 miles ~ 320 km at (assume, on the optimistic side) 3 l/100 km => burn 10 litres of petrol. There's 13 kWh in a kg of petrol so one litre holds 13 x 0.8 (density) ~ 10,4 kWh. So those 10 litres burned are equivalent to 100 kWh or a bit more. To charge 100 kWh in one hour takes 100 kW power (and that's assuming a 100% efficient charge process) - to do so in 6 minutes = 1/10th of an hour requires 1 Megawatt. Not something to take from a 230V~ socket or you would need VERY solid cables. And a power plant VERY near by.

Someone please check my maths? It is getting late. The 13,0 kWh/litre is from en.wikipedia

I was actually shocked to meet pilots at my current club that had never flown a plane with carb heat
To each their own To me it is shocking that there are pilots who do fly with such paleo-primitive technology.
