Researchers at the University of St Andrews see promise in new battery technology using air as a fuel and say it could provide 10 times more power for electric cars, mobile phones and laptops
The Stair cell is expected to be cheaper than rechargeable batteries of today, the researchers said. The new component is made of porous carbon, which is much less expensive than the lithium cobalt oxide it would be replacing.
"The key is to use oxygen in the air as a reagent, rather than carry the necessary chemicals around inside the battery," Bruce said.
This image shows a diagram of the Stair, indicating how oxygen drawn from the air reacts within the porous carbon to release the electrical charge in the battery.
The four-year research project began two years ago and is scheduled to end in June 2011. Bruce expects it will be at least five years before the Stair cell is commercially available.

Fantastic idea imagine a world without power cords :D, I wonder if they could also make it draw in carbon along with the oxygen and recycle that too.
