Motorola curiously shows off fuel cell technology at MWC

Okay, we suppose cellphone companies trumpeting some sort of fuel cell technology isn't that weird, but nevertheless, Moto sure seems proud of its most recent advancements. Showcased at this year's Mobile World Congress are a number of "alternative power solutions including fuel cell and reflow batteries," which can be deployed in most every wireless / mobile environment out there. More specifically, the outfit is demonstrating a fuel cell-powered WiMAX base station, and it's also suggesting that said technology could "further guarantee [the] availability of uninterrupted power" in TETRA radio networks that are used in public safety environments. Fascinating, no?

Ghana man killed by exploding handset?


Truth be told, we aren't exactly inclined to believe this here article is entirely accurate, but nevertheless, Modern Ghana is reporting that a resident was recently killed by an exploding cellphone. Notably, this unfortunate accident wasn't due to a faulty battery, or at least that hasn't been blamed just yet. Rather, the young man simply answered his ringing mobile while it was still plugged into the wall, and seconds later, electricity flowed into the cellphone unrestricted and threw the man back. Reportedly, he was pronounced dead on arrival at a local hospital, and we're sincerely hoping that investigators get to the root cause of all this if indeed the tale is true.

Researchers hope to charge up gadgetry with body heat


We've heard of firms tinkering with the idea of converting excess heat directly to energy, and apparently, a team of scientists from the US Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley have done just that. Oddly enough, the researchers admit that they're still unclear on how their findings actually work, but they've nevertheless discovered how to increase the conversion efficiency of converting waste heat to energy "by a factor of 100." The authors of the report suggest that clothing constructed of material embedded with thermoelectric modules could one day "recharge mobile electronic devices off the heat of one's body," and while we're certainly stoked about the idea, we're already conjuring up awful images in our minds about what this garb will actually look like.

Seiko Epson, Murata team up on contactless quick charger

Not even a week after startup WiPower boasted about its breakthrough in wireless power, Murata and Seiko Epson have announced plans to "jointly development a non-contact quick charging system." Reportedly, the technology "leverages electromagnetic induction," and both the charging stand and a given mobile device would be "respectively equipped with coils that generate power." As for the production, it sounds like Seiko Epson will hone in on the "transmitting side, or primary side," while Murata "will be involved in the production of the rechargeable Li-ion." The overriding goal is to recharge a handset "in about 10 to 15 minutes in a non-contact manner," which would purportedly push power transmission efficiency from current levels of 30- to 50-percent to nearly 70-percent. Oh, and we've already been assured that these "will not generate heat."

NEC develops M2 LSI chip to conserve energy in cellphones

Hot on the heels of a snazzy new CMOS sensor and newfangled plastics, NEC's engineers are cranking out yet another innovation to make our next phone a lot more useful (for a whole lot longer). The M2 system LSI chip can purportedly "drastically cut the energy used by a cellular phone" by halving the energy needed by each element on the chip. Notably, the firm has suggested that a cellphone battery currently lasting seven hours would be able to maintain that life even if "twice the power is required for high-speed telecommunications." A host of sophisticated technologies and software regulations are behind all the energy conserving magic, but the news you care about is that NEC plans to start shipping samples of the ¥5,000 ($41) device in the very near future, and it should hit a variety of 3G handsets by the year's end.

Modded flashlight doubles as cellphone charger

Although most modern phones can go quite a few hours sans an AC outlet, we understand the need for juice in unexpected emergencies, and while the solar-powered charger does a fair job at high noon, you'll probably need a different approach come nightfall. Tackling two issues in one fell swoop is the cellphone-charging flashlight mod, which not only provides a beacon of light for those dim excursions, but also offers up hand crank recharging abilities for your fading mobile. Of course, hacking your flashlight to pull double duty as a manually powered charger is a bit more complex than just picking up a hamster or bicycle-powered option, but you've got to admit, crafting a makeshift charger with spliced cables and a soldering iron is totally MacGyver-approved. So if you're interested in giving yourself (and your handset) a bit longer life when robotic overlords eventually invade our domiciles, be sure to hit the read link for a video demonstration, and do mind the managerial cat on duty.

Samsung develops 1Gb synchronous DRAM module

Apparently, Samsung has been on quite the rampage (ahem) lately, busting out its new Powerhouse Fusion memory, working with NEC in hopes of crafting a one-terabit chip, and now announcing the industry's "first gigabit-density mobile DRAM" module. Using 80-nanometer process technology, the 1Gb synchronous DRAM module claims to be "more cost effective than other high density mobile solutions," and requires around "30-percent less current" than the double-die stack chips commonly used today. The monolithic chip introduces a new "temperature-sensing feature" that purportedly maximizes the "self-refresh cycle" to reduce power drain in standby mode, and also touts a 20-percent decrease in thickness over its predecessors. While we've no idea how much these modules will bump the price of your future gadgetry, they should begin finding their way into "handsets, digicams, PMPs, and handheld gaming machines" in the second quarter of 2007.
