Charging infrastructure, now i have been thinking on this as well but i see a problem that needs to be solved. The average car is say 100kw and needs to be charged every night (true not with 100kw) but hen the typical house is say single phase 50 amp so thats some 12 kw hmm seems to be a bit of a short fall here you need 8 hours to charge your car and you can do this, but i know the power grid will no way handle this at all as i think there is a massive rounding done by power suppliers so if there are 100 houses with the 12kw supply the suppliers will say only 1/3 of them will need that much power at any one time so the supply is dropped at this point. But when we all come home and start charging our cars the grid blows up. So how is this solved 1 way is * of the little solar cells 6kw on a roof and start putting in 50kw solar systems on house roofs but then some houses don't get that much sun light or there not big enough. SO then what i have a big roof and no shade so i can put in 100kw and sell the excess to the block next door who loves trees and has to much shade. AND of course i have to install a sheet load of batteries, but they are house batteries, So who cares how much they weight you don't have to move them. So should house batteries be lithium at all. why not simple as salt water batteries, so Now we need to design the house and make the battery the entire floor cast it in concrete and fill it with salt water. Could this be a solution. Damn would be good to get hold of the right idea here. think i need to sit down and do some serious numbers. Not really on topic i know but still darn interesting thought bubble if any one has other ideas please let me know.

Gary, you are all over the place here. Slow down a bit and come back to reality. When you say car with 100kW I guess you meant 100kHh; this is usually enough for 500-600km; I'm doing this in about a week. So, I need to charge about 15-20kWh every night. The 50A/12kW charging is totally fine for day-to-day usage.
