When I built my electric bicycle back in 2007, I had been waiting for a battery that was less volatile than what had been available. I didn't want to risk having a fireball under my seat. Tesla traded volatility for power density.

I think electric cars are great for all kinds of reasons, which is why I bought one in 2011. But like any car, they are not created equal, and as marketers begin the process of differentiating them to get us to buy them, that inequality will grow and diversify as it has for conventional cars. And for any fellow electric car enthusiasts out there who think electric cars are going to make a significant dent in carbon emissions in the foreseeable future, read Robert Rapier's article on that subject. Even a strongly biased study by the UCS shows that electric cars, on average, presently produce about half of the emissions of conventional cars in a cradle-to-grave analysis. Eliminating fossil fuels (instead of nuclear) from our energy mix will improve that over time.
