Mobile Phone Charger That Runs On Water

A Swedish company has invented a charger for mobile phones, cameras and GPS devices that can power-up your electronic gadgets with little more than water.

The PowerTrekk has been designed for people who 'who spend time away from the electricity grid' and do not have access to conventional power in remote locations. The charger needs just a tablespoon of water to produce around 10 hours of phone battery life.

The invention works with any device that has a USB port and with almost any type of water, including salt water. It can even run on puddle water providing it isn't thickened with mud or any other sediment.

"PowerTrekk has a competitive edge over traditional portable chargers" said Björn Westerholm of myFC, the company behind PowerTrekk.

Fuel cell power is generated immediately and charging is not impacted by weather or the position of the sun, as for solar panels. Compared to battery powered travel chargers, PowerTrekk offers reliable charging as the fuel packs do not deplete as batteries do.

The process is easy for users. The sodium is stored in a small round container called a PowerPukk. The PowerPukk slots into one half of an outer container. In the other half is a tiny water tank, into which you pour the water. Once the lid is sealed on the outer container the chemical reaction begins automatically and the PowerTrekk is ready to use.

The chemistry process is said to be safe and eco-friendly, and the only by-product is a little water vapor.
