Nilsen: do you have any Watt consumption figures pr km?
AFAIK, where I live it would be 1/5th or less of the ´petrol costs, so if one is doing short distance driving, this is very very interesting. Would gladly trade some space for extra batteries for an endurance of some 200 miles, and where I live the energy is clean.
Then there is the question of charging time. With seperate battery "tanks" it wouldn´t have to be so bad, charging many at a time....
I am quite positive towards electric cars.
BTW, in my country the KW goes for about 5-6 euro cents, while the petrol is about one euro or even more.
Come to think of it, in countries like ours, who use clean energy for smelting etc, a society where most of the cars were electrical would provide power buyers paying vastly more than the big industrial corporations, ´i.e. you, me and the rest....
