From the Wikipedia's EEStor article, you CAN fast charge at home without a ridiculous electrical system -- IF you have a second EESU that slowcharges overnight:
http://en.wikipedia.org/wiki/EEStor
"Overnight charging at home should still be practical,[6] as is using a second EESU for the home which could be charged overnight using cheap, off-peak electricity to then charge the EEStor unit in the car in 5-10 minutes on demand - and deliver cheap electric power to the house too, making expensive peak power plants obsolete.[7]"
I think once you wander through Grayditch, you'll notice some ants...
It's a naive, domestic operating system without any breeding, but I think you'll be amused by its presumption.
