Sure, Voller's fuel cell-based Automatic Battery Charger (ABC, isn't that clever?) can power your iPod for a whole week of tunes, but you've got to ask yourself: "can my playlists take that kind of heat?" Remember, there's only so much James Blunt the world can take, and he's quickly reaching his quota. Luckily, the ABC can handle some much more reasonable tasks, since in addition to a USB port, it can pump power through a cigarette-lighter socket and a regular ol' wall socket. The device runs on hydrogen stored in a Polymer Electrolyte Membrane fuel cell, stored in a removable tank. Not quite the pinnacle of fuel cell tech, and a far cry from efforts of those like Toshiba who are trying to squeeze this power source into a laptop, but its clean energy and quite plentiful, so we can't complain.
