Elon Musk Says Larger Batteries Might Be On the Way

mknewman writes "Elon Musk intimated that more-powerful batteries could be on the way for the Model S. The most potent battery pack currently offered in the Model S holds 85 kWh of juice, or enough for 265 miles of driving. Musk wasn't terribly specific, however: 'There is the potential for bigger battery packs in the future, but it would probably be maybe next year or something like that. The main focus is . . . how do we reduce the cost per kWh of storage in the battery pack?' In other words, Musk seems less concerned with stronger battery packs than making cheaper battery packs for the upcoming mid-size sedan, which is expected to be unveiled at the 2015 Detroit auto show. 'Our goal is to drop the cost per kWh by 30 percent to 40 percent.'"

FAR better than fossil fuels, and even better tech

[Centrist Review]

As the other responder said, the danger of fires with batteries is far less than that with fossil fuels, but even more - there is tech a few years off that will make them even safer. Just the other day someone developed a form of lithium ion battery that is significantly less prone to fire, which is amazing given how much energy is stored in those things. It's nearly impossible to design something that holds such an enormous amount of energy without it being dangerous if damaged and accidentally discharged.
