Not wanting to pee on anyones parade but how is the extra power required to charge these cars gomg to be generated? Anyone with a bit of basic physics will tell you that everytime something changes status energy is given off and lost. So, instead of getting petrol from crude oil (say 20% inefficiency) and powering a car (say another 20%) we are going to convert the fuel to electricity (and loose another 20%) before we change it to motor power?

No, sorry, wind powered cars are the way forward. Not sure of the efficiency of converting all those beans to enough wind for my personal use but I'm sure spaw has enough to spare...
