Comment Lots of potential (Score 1) 178
This strikes me as having potential to augment the traditional battery in a car. I don't think it will replace it, nor should it. Combine this with a moderate sized battery and you extend the range of the car dramatically. Better, you can have two different systems optimized for different uses, one a slow charging energy dense battery and the other a quick charging efficient capacitor mopping up regenerative breaking energy and delivering it in a quick burst. Add in a few other systems such as integrating solar power to help run the increasing number to gadgets in cars and the electric car starts to really shine.
