Story...Waiting hours for a cellphone to charge may become a thing of the past, thanks to an 18-year-old high-school student's invention. She won a $50,000 prize Friday at an international science fair for creating an energy storage device that can be fully juiced in 20 to 30 seconds.
Teen's invention could charge your phone in 20 seconds!

If the energy density attainable in supercapacitors can be increased significantly (and successfully, outside the lab!), big changes might be on the way. Satisfactory electric cars is just one of the things to spring to mind.
The problem of preventing a catastrophic, instantaneous accidental discharge of all that stored energy - !BOOM! - remains to be addressed.
(What has this to do with Puppy? Well, for a while now I've been wondering whether I could use supercaps to overcome a longstanding problem - the habit of the electricity company of giving supply dips too brief for the UPS to cut in, juuust long enough to lose RAM content, juuust before I was due to save stuff to disc. Grrrrr! Guess that might be worth a thread of its own).
