It has been done. But you have very limited places to go if you are going to use alternative energy sites. There was a TV series done about it. Just not with the Tesla.

Most houses can't use more than 150 Amps, before the system overloads, and given that you'll be using 30-50% to run other houshold appliances, ovens, etc., means that you've probably got 100 Amps to spare for the car. Or about a one-fourth of what's needed for a 3.5 hour charge. So the charge cycle will be more like 14 hours.
And just imagine how much of the earth's resources you burnt while earning the $100,000 to pay for the machine!.

Actually, the price is more like $80,000 but you will get some money back if you are in California.
As for the needed electrical infrastructure for the car garage or carport, you don't really think you are just going to plug in the car into your house wiring, are you? You have to get 204/240 wiring into the garage and if you are always running about town, there will be periods when you will be active where it will get a partial charge and then you are back out on the road again. It will be the same if you are installing something big like central air or a 1.5k linear amplifier.
Since you brought it out, how about the Land Rover? The extracted Aluminium used in the body is very energy intensive. So is the magnesium and the processes to make the Durabright. Not to mention the various fluids and the energy used to make the premium fuel to get it going. How about the peripheral costs past along to the customer like the energy used to operate the gas station and its subsystems (those lights cost money too you know).

There are no current laws regarding end-of-life recycling of the whole car, but Toyota have protocols regarding battery replacement and recycling for their product(s). I believe it is the same with the Tesla until somebody notices the large stack at the back of the dealer.
If you have your own "Indy" mechanic for the Tesla, you will do as most others do and keep up with like-minded owners. (like this group). As for the Lithium-Ion batteries, you could always change them to another technology or the next New Tech. It would be interesting to make it a hybrid or even a methenol fuel cell type. Then you are off the grid.

Don't get me wrong. I think that the Tesla Roadster raises the ante, and would love to own one. But they shouldn't try to sell it as a "green" conscious thing. It's simply an expensive toy, and WOW, 0-100km/h in 4 secs! It outperforms it's look-alike Lotus Elise cousin... That's the unique selling point! Not that it's an environmentally friendly alternative.
Forever the cynic...

I think you should have read the article in Wired News. The owner of the company used Lotus engineers so much he had to sign an anti-poaching agreement. Seems he took all the talent away from Lotus.
Will it sell? In California and Monaco and New York, it will be popular. Also in Iceland and anywhere someone wants to make a statement. They are already working on a sedan.
