Researchers at the Massachusetts Institute of Technology are working on a new device that uses carbon nanotubes to store and release electrical energy in a system that could carry as much power as today's lead or lithium batteries.
But unlike the rechargeable batteries used on today's cellphones and laptop computers, these devices could be recharged hundreds of thousands of times before wearing out.
And instead of taking hours to recharge, they could be powered up in about the same time it takes to fill up a gas tank. ...
The device being developed at MIT's Laboratory for Electromagnetic and Electronic Systems isn't a battery, but a capacitor -- a device that's already used in nearly every electronic product on the planet. When plugged into an electrical circuit, a capacitor briefly stores incoming electricity, they releases it at a predictable rate. Capacitors can't store very much power, compared to traditional batteries. But while it takes hours to recharge a battery, capacitors charge almost instantly. And while most batteries can only be recharged a few hundred or thousand times before wearing out, capacitors can be recharged hundreds of thousands of times.

MIT RESEARCH MAY MAKE BATTERIES OBSOLETE
We knew our friend MIT was talented, but we had no idea that he knew nanotube technology. The Boston Globe says:
Pretty cool, if it ever comes to pass.
