Ultracapacitor 101: Pros and Cons

Anyone who's interested in getting the transportation sector off oil by electrifying it has daydreamed about ultracapacitors and hypercapacitors. Lots of people are working on improving them, and if (when?) we can make them store enough power, they would be an almost perfect replacement for batteries. They're relatively light, they can charge and discharge power extremely rapidly, they can be cycled a virtually unlimited number of times, they don't require exotic materials to make, etc. But sadly, we're not quite at that point yet. Our friends at Gigaom have a great primer on ultracaps and what makes them great and not so great. See also: MIT: Move Over Batteries, Here Come the Nanotube-Enhanced Capacitors
