Sony showed off some fuel cell prototypes at the Fuel Cell Expo 2009 in Tokyo. Pictured are some fuel cell-powered speakers and a charger that create power with only pure water as a byproduct.
The silver speakers can play music and power a mobile device, while that thing that resembles a coffee maker is a completely wireless speaker system that is capable of running for months with its container of ethanol. The blue thing will charge up anything with a USB port.
We hope it won’t be long until we have this kind of stuff all over our desks. Hopefully with less explosive liquid components.
