Among the details CEO Elon Musk gave today about Tesla Motors’s new upgraded fast-charging network was this: Within a few years, it will have hundreds of charge stations across the country that will be equipped with solar panels and batteries, allowing them to run “even if the entire national grid goes down,” he said.

He went on to put one major worry people have about electric cars to rest: “So, I was joking with someone that even if there’s the zombie apocalypse, which is a popular theme these days, even if there’s a zombie apocalypse, you’ll still be able to travel throughout the country using the Tesla supercharging system.”
