Mobile phone charger that runs on water invented for 'people who spend time away from the electricity grid'

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.
