And how much energy is lost charging batteries? Because there are no native sources for charged Tesla battery packs. You're either using electricity to charge them at your house (with 60% lost in transmission) or charging them closer to the power plant. It's more efficient to simply use hydrogen. I don't understand why anyone would be convinced by arguments like this that don't include numbers, when you can make the argument sound equally valid on either side of the debate.

Only if you fake your numbers by an order of magnitude, see above. > I don't understand why anyone would be convinced by arguments like this that don't include numbers. Still better than your astroturf numbers. If hydrogen is better, so be it. However, the Tesla S can go 450km with one charge today and it can be charged everywhere. An electric car is the nightmare of traditional car manufacturers: an electric motor costs nothing and lasts unlimited kilometers. You need no engine oil change, the brakes last a lot longer and cars will easily last 1.000.000 miles / kilometers and a lot more with little maintenance. You do need to change the battery but this is not money for the car manufacturer. So there are two huge industries for which e-cars are a nightmare: petrol and classic car manufacturers. Disclosure: I drive an MiEV an it works amazingly well. [1] http://de.wikipedia.org/wiki/%C3%9Cbertragungsverlust http://de.wikipedia.org/wiki/%C3%9Cbertragungsverlust (german)
