Right then. As you may already be aware, I somewhat favor ultracapacitors. Anyways, apparently some university students have found that using Maxwell's ultracapacitors, they were able to start an ICE with a regular starter 10 times at 20 degrees from a full charge, using an ultracapacitor pack weighing only 1.7 kilograms.
Such a pack would have an effectively unlimited lifetime and would be quick to recharge too. Anyways, I saw this on Maxwell's site so I thought I'd post the link:

There's two experiments done there, one using older, obsolete ultracaps to run the starter on a test bench, and a second using current generation ultracaps in a "real world" test inside a car.
