Fuel cell outfitter Horizon is now offering a personal hydrogen power plant for use with its MiniPAK and HydroSTIK products. Although it isn't cheap, the system will (cleanly!) charge all of your small devices using the same water you drink.
First seen at CES years ago, Horizon's MiniPak has (finally) gone on sale for $100. It's the first personal, portable fuel cell—if you don't count the Japan-only Toshiba one—and is like a mini power plant for charging gadgets.
