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.

Although Energizer has been providing its Energi To Go for a plethora of cellphones and other portable peripherals, it's about time the dock-connecting iPods got one of their own. Finally arriving this fall, the Energi To Go Portable Power for iPod is powered by a pair of AA cells, sports a "unique flip design" that enables it to double as a stand, and features a "patented intelligent control chip that maximizes power transfer to the iPod." 'Course, what you're really interested in is how many all-nighters this thing can get you through, and we're happy to say that this here gizmo can supposedly provide "more than 46-hours" of juice to an iPod nano and "more than 32-hours" of music playback to the iPod with video. All yours for $29.99, which will include the charger and two Energizer e2 Lithium AA batteries.

Yeah, we won't even need fuel cells as soon as EEStor's miracle-working ultracapacitor-based battery system starts powering the world at large, but until then, we're still fielding applications for alternative sources of juice. Medis Technologies has introduced a fuel cell for your pocket, which provides auxiliary power for cellphones, DAPs / PMPs, PDAs, digicams, and pretty much anything else that relies on an internal, rechargeable battery. Touted as being "years ahead of its time," this self-proclaimed must-have gadget works off a Direct Liquid Fuel Cell (DLFC), and can supposedly provide up to 30 hours of talk time to any mobile, and between 60 and 80 hours of playback time for your iPod. Of course, there are no hard details promising us when we'll see this portable power unit, nor any indication of how expensive it'll be when it finally lands, but if lofty life claims turn out to be true, it might not be too shabby.
