Charge your phone using water? It may sound like science fiction, but it’s actually science fact! Just pour a tablespoon of water into the Powertrekk’s fuel cell and it is converted into electricity using physics and/or chemistry. Unlike solar devices it provides instant power, and doesn’t rely on good weather. It’ll charge anything that uses USB, from your tablet to your camera. A true lifesaver and a view of the future. $229,
