New micro power source
No, it's not fuel cells. Nor is it cold fusion.
It's a tiny combustion engine built on a silicon chip (story here). My oh my... to see the look on Henry Ford's face had he been told that one day his combustion engine could power an iPod for 10 times longer than a lithium-ion battery.
I wonder where you would re-fill them? I think the pumps at the local Esso may not work well.
