There was a movie in the 80's about a futuristic motorcycle that could run on ordinary gasoline, or, with a Power Cell the size of a Game Boy, it could run on Hydrogen gleaned from moisture in the air.
We are one step closer to living that dream.
Samsung has created the first "micro-fuel cell and hydrogen generator that runs on H2O." Pretty soon, everyone's going to get in on the action, and that means better technology at low low prices.
How does it work, you ask? Water in the phone interacts with some metal, producing hydrogen which is sent to the fuel cell. There, the hydrogen interacts with oxygen and produce 3 watts of power.
First-generation cartridges will need to be replaced after only two uses, a shortcoming that will hopefully not last too long once the technology develops. But two uses at 3 watts a pop is about 20 hours of battery life. Not too shabby, for water power.
