While still quite a ways away from our ideal method of drawing power directly from tap water, the new HydroPak generator from Millennium Cell and Horizon Fuel Cell at least trumps those heavy, dirty, traditional models in both cleanliness and efficiency. As we first heard a few months back, this water-activated, fuel cell-based "portable power product" uses $20 disposable cartridges to provide "enough energy to recharge an average notebook computer 8 to 10 times" or "operate low power devices such as portable lights, notebook computers, portable televisions and ad hoc communications networks for more than 14 continuous hours," via AC outlet or dual USB jacks. Also on display at CES alongside the $400 unit will be a smaller version called the HydroPak Mini, a prototype device designed to juice up gadgets such as cellphones or gaming systems.

We've seen our fair share of diminutive power generators, but rather than worrying with vibrations or hyperventilating, Millennium Cell and Horizon Fuel Cell have teamed up to deliver an iteration that's water-activated. The pair has been working together on this technology for some time now, and apparently, it's readying a beta that will be demonstrated at next year's CES. The portable power generator incorporates a "unique water-activated cartridge system," which is designed to quietly provide clean energy to consumer products in emergencies and when far, far away from an electrical outlet. Reportedly, the device will provide an AC socket alongside two USB connectors, an operating time of over 16-hours, infinite shelf-storage life and 400-watts of instant juice by just adding H2O. Regrettably, we still have no idea what this thing actually looks like, but considering that CES is less than two months away, we'll soon be seeing what this $400 gizmo can do up close and in person.
