| Tesla Roadster |
The Tesla Roadster runs on laptop batteries. Lots of them. Martin Eberhard, co-founder of Tesla, is predicting that EV's will have a 500 mile range by 2020.
Eberhard says that five years ago Tesla were using 1.4 amp-hour cells. Now the same size cell is available in 2.9 amp-hours with 3.4 amp-hours coming soon. This is amazing progress, driven by global sales of 2 billion laptop batteries a year.
