I wish I could believe the Tesla will work...

I really do. It's a 4 y.o. start up auto company that makes just one product: a swoopy sports car. It's fast. It's lowslung. It looks the business. It costs a reasonable $US100K. And it runs on electricity. I just want to believe in it, I really do.

I just wonder what happens when you get stranded for the first time. When the batteries start to lose their zip. Do you pull over and run an extension lead over to a friendly local 220V public power point and wait for 3 hours? Or plug into a more common 110V socket and wait 7 hours, happily? What happens when you forget to charge up overnight (maybe the car emails you a reminder?). Do you go 'oh well' and walk? Hmmm. It's not like a gasoline car, is it, where you just go to a petrol station and refuel in a couple of minutes...

The other thing is, who makes the electricity, and how? Do we really save anything, when we are in effect burning coal to run the car? I'd like to see the sums...
