Think Ultracapacitors are pie in the sky?

...then have a look at one of the first consumer products based on an ultracapacitor....a flashcell screwdriver! Thanks ultracapacitors.org. There may be an EEStor product in our future after all.

Here's the link to the overview on the Coleman Flashcell Screwdriver. It charges in 90 seconds. It can withstand 500,000 charge cycles. Amazing!!!
