Talking to the Tesla roadster guy at the show I discovered 2 alarming things. (The Tesla roadster is a 100% battery powered sports car delivering exeptional performance!)
1) Batteries need replacing after 5 years
2) Batteries cost £9000 ($20,000)
This kind of makes the penny a mile cost in fuel saving seem irrrelevant?
Also to charge it quickly you need more than the 25 amp power supply we get in our houses and all quoted charge times are for 90% the other 10% takes another 3 hours.
I say "chuck away the batteries and run a small petrol generator instead".
