Could 2010 finally be the year of the fuel cell? Horizon thinks it will be. The company has been teasing us with products for years, and while this latest one is also just a promise at this point, Horizon says it will be for sale by the end of the year. Hydrofill is a "personal hydrogen station" capable of converting water into hydrogen gas, which then gets stored in small cartridges called Hydrostik -- apparently in a crystalline structure to prevent your fanny pack doing a Hindenburg. Those cartridges will be usable in rechargers, like the Minipak, which provides USB output to recharge smaller gadgets on the go. It'll surely be a little more powerful than the toy kit Horizon released back in 2008, but we're bummed this one won't run on vodka like that one did. We tend to have plenty of that lying around this time of the year.
