Gizmag, a website that features the latest and neatest gadgets any nerd would want, has this piece on an interesting charging gizmo made by Stockholm's myFC and SiGNa Chemistry: the PowerTrekk, a water-powered fuel-cell charger.
The charger is composed of a Li-on battery and a hydrogen fuel cell cartridge called the PowerPukk. The cartridge, which contains sodium silicide, can produce hydrogen from water -- any water, even waste water -- and the chemical reaction that follows can convert the hydrogen into electricity.
About a tablespoon of water is added to the central well of the PowerPukk after it's placed inside the belly of the PowerTrekk, after which the device's Proton Exchange Membrane starts to silently convert the hydrogen into electricity. The only by-product of the process is a little water vapor.
Aside from the insane thought that I could check Twitter while camping, the charging abilities of just one PowerPukk can handle "2 smartphones or 15 iPods" and have a shelf life of "two years minimum."
