Cellphone lights enable operation to proceed in blackout
Hearing that a cellphone saved someone's life isn't exactly surprising these days, but it was the manner in which a bundle of handsets enabled doctors to continue on in a recent operation that differentiated this one from the rest. Reportedly, the backup generators at the Policlinico Juan D. Peron hospital in Argentina failed to activate after the power went out whilst an appendix surgery was ongoing, but rather than panicking, a family member gathered up a number of phones in order to provide enough light for the surgeons and anesthetists to keep on keepin' on. According to the hospital director, the operation went on without proper lighting for no more than 20 minutes, but thanks to the beaming LCDs, the fellow under the knife came through just fine.[Via Switched, image courtesy of foto8]
Tiny generator turns vibrations into electricity
We've seen a couple interesting attempts to convert vibrations and sound into electricity, but the latest design from a team at the University of Southampton is the first we've come across that's designed to be attached to bridges, large buildings, and other structures. The sugar cube-sized generator, a smaller version of a design already commercially available, uses cantilever-mounted magnets to induce a current in a copper coil -- a use of magnets to generate electricity that doesn't violate any laws of thermodynamics, which is always appreciated. The team has successfully used the generator to power an accelerometer (pictured), and tests indicate that the unit can put out up to 46 microwatts of power -- enough to run a pacemaker off the vibrations of the heart itself. No word on commercial availability, but the team seems like they're ready to get shaking fairly soon.
Breath powered USB generator does charging on the go
Hey, we're tired of waiting for wireless charging solutions to actually hit the market just as much as the next guy (or gal), but one inventive soul took that frustration out on a swank DIY project that elicits energy from simply breathing. We've seen the use of hot air in powering gadgets before, but this homegrown USB charger was assembled by simply using "parts scavenged from an old CD-ROM drive, a basic electronic circuit, and a few rubber bands." The chest-worn device was intended to output around one-watt for charging a cellphone, which could purportedly juice it up in just under three hours, but unfortunately for us all, this seemingly brilliant device only mustered about 50mW of energy. Of course, that's still getting somewhere, but we're not exactly keen on wearing this thing around for an entire day in order to add a few battery bars to our mobile. Nevertheless, the creator doesn't look to be giving up on it so soon, and hopefully v2 will allow our breath to add new life to our lappies or electric cars, eh?[Via Slashgear]
Thermoacoustics behind all-in-one cooker, fridge, and generator
Sure, building up a campfire in order to roast some eats in the wilderness could be fun for awhile, but for the reported "two billion people that use open fires as their primary cooking method," we're sure it loses its luster somewhere along the line. The University of Nottingham is hoping to change all that, however, by attempting to develop an all-in-one gizmo that acts as a "cooker, a fridge, and a generator," and relies on biomass fuels for energy. The £2 million ($3.96 million) SCORE (Stove for Cooking, Refrigeration and Electricity) project seeks to create a "wood-powered generator capable of both cooking and cooling food," and it will purportedly rely on thermoacoustics to cut down on pollutants, increase efficiency, and be more reliable to future consumers in Africa and Asia. No word just yet on when this newfangled kitchen appliance will be ready to ship, but a portable version would probably do quite well in the camping market.[Via CNET]
Judgment generator is guilty of being awesome
Capcom is promoting its release of Gyakuten Saiban 4 (Ace Attorney) in Japan with a "judgment generator" video that anyone can drop faces and text into. The short clip's scene depicts a group of reporters waiting outside a courthouse as a man comes running towards them to announce the jury's decision. The verdict? That's up to you to decide!The prompts to enter text and upload/crop images are all in Japanese, but it shouldn't take you longer than a few seconds to figure out what's required. Why not mock up one of your own, and comment with a link to your video? You'll have to keep Japan's right-to-left text placement in mind and also compensate for the ten-character limit, but we're confident that you'll come up with something creative! We've already made a couple that you can see after the post break!

Inventor builds goliath smoke ring generator
While it's easy to appreciate an invention that makes all of our lives a touch easier, it takes something truly exceptional to be both impressive and completely useless simultaneously. Such is the case with the curious (and gigantic) smoke ring generator, which looks to crank out giant rings of slowly fading smoke while onlookers beg for "just one more." The hand-powered device starts by launching a ghostly orb, which hastily slows and forms the infamous circle that brings back all sorts of gangster flick-related memories. Now, where's the step-by-step instructions to build one of these bad boys? Oh, click on through for the must-see video.[Via MAKE]
Georgia Tech researchers develop environmentally-powered nanogenerators
While the school of the Ramblin' Wreck may be best known for its barrage of engineering graduates, the university has been on quite the medical trip of late, as researchers have reportedly developed a nanometer-scale generator after already cranking out nanowires that monitor your blood pressure. The aptly-named nanogenerators can produce "continuous direct-current electricity by harvesting mechanical energy from such environmental sources as ultrasonic waves, mechanical vibration or blood flow," which translates into easy energy for implanted and worn medical gadgetry of the future. Interestingly, the project was funded by the likes of the National Science Foundation and our pals at DARPA, and while this invention may not quite match up with wireless charging (hey, we're scared of hospitals), the concept is novel nonetheless. So if you were hoping that dreams of implanted analysis of your vitals would suddenly cease, things aren't looking up for you.[Via MedGadget]
Armory + Signature Generator = AWESOME!
Now that everyone you know is looking at your stats in the Armory anyway, isn't it time you showed off your character in whatever online forum you happen to take part in? From guild forums to public bulletin boards, there's always room for a fun, graphical signature. Just look at mine, above. It has my mean Draenei face, some lightning bolts, and even my awesomely hardcore (ha ha ha ha ha) stats. Head on over to http://jebus.geek.nz/WoW/armory/ to get your very own signature image, which you can download to your desktop, then upload to your favorite forum hangout. You can get it in PvP and PvE flavors, in a variety of colors and backgrounds. It's not perfect, as Skew was complaining to me earlier that the Shaman tag doesn't show stats meaningful to enhancement shammies. Any other stats it's not showing that you'd like to see? What are you using as a signature in the forums now, and do you see a little tool like this to be as handy as I found it?
Motion-sensitive "power skins" could generate power in space
Just in case you ever plan on heading up into space to see your soon-to-be-painted logo on the Y*N*I*S satellite up close and personal, you might be interested in this. Devised by researchers at a Cambridge-based venture, dubbed IntAct Labs, the motion-sensitive "power skin" could be used and worn by humans and inanimate objects alike in order to generate electricity, and the concept was derived from our very ears. After investigating how biological organisms are such "ultra-efficient generators of power," the crew homed in on a tiny protein called prestin, which can "convert electrical voltage into motion or produce electrical charges in response to mechanical stresses," and is actually found in the outer hair cells of the human ear. Ideally, networks of these proteins would be linked in order to form skins that could coat people or objects and generate energy from something as simple as walking around or being in the path of wind gusts, and if everything pans out, a prestin-powered research station could be set up on Mars without a manmade perpetual power source in tow.[Thanks, Sparky]
Portable generator converts waste into energy
Although developing alternate fuel sources is most certainly a worthwhile effort, a group of Purdue scientists are looking to demolish two birds with a single, um, bag of refuse, as its portable generator not only creates useful electricity, but it disposes of worthless garbage while it's at it. The aptly-named "tactical biorefinery" processes several kinds of wastes at once, which it then converts into fuel via two parallel processes before burning the results in a diesel engine to power a generator. The device, which comes in just a hair smaller than a "small moving man," can crunch through multiple kinds of garbage at once, creating energy completely without discrimination towards certain kinds of gunk, and is already being eyed by the US Army for future battlefield usage. Interestingly, initial prototypes are showing that it can produce "approximately 90 percent more energy than it consumes," and considering that it pulverizes everything inserted into it, soldiers won't have to worry about leaving behind remnants of their stay. Ideally, the backers would love to see the unit available in commercial settings as well as in the military, but we think this thing will be a real winner when it can compress gobs of garbage into vicious (smelling) pellets and launch grotesque projectiles while keeping our planet green.[Via CNET]
Personalized Zelda "take this" generator
When we saw this, we knew it was right up our alley. Given our love of generators, we knew you folks would appreciate this as much as we do. It isn't only restricted to the original Zelda game, either, allowing one to mess around with Link to the Past as well. The whole spectrum of possible images is one that is so gigantic that it causes our brain to melt down into a smooth, oily paste, slowly secreting from our ears and eventually falling to the floor, nothing more than a small puddle of steam and disgusting fluid.With that horrible image in mind, be sure to post your creations in the comments section!
Engineuity developing hydrogen-creating, emission free vehicle
Just in case there weren't enough alternate fuel developments going on around the world, it looks like we've got yet another vying for business over in Israel. Engineuity, a company started by Amnon Yogev, has reportedly developed a method for vehicles to "produce their own fuel" using metals such as magnesium and aluminum to create hydrogen and steam. Similar to a solar-powered "zinc-to-hydrogen" approach that gained attention in 2005, this method utilizes a "long metal coil" which would be inserted into a metal-steam combustor that stands to "separate hydrogen out of heated water." After intense heating, the metal atoms would purportedly bond to the oxygen from the water, creating metal oxide; the result would free up hydrogen molecules to be sent to the engine alongside the steam to provide the juice. The firm also insinuates that "refueling" the vehicle would be "remarkably simply," and construction could be completed on current production lines without requiring entirely new infrastructures. According to Yogev, the "running cost of the system should be equal to that of conventional cars today," and hopes to have a full scale prototype ready to rumble in "around three years."[Thanks, Mike]
Turn Google gadgets into widgets, widgets into apps
Google, like seemingly almost every other web services company on the planet these days, offers a personalized Google homepage that allows you to customize the page with more or less the internet version of widgets. Google calls them gadgets, and you can drag and drop them to create just the page you want.Recently, Google announced they were breaking the chains that bind their gadgets to their homepage, allowing anyone to copy and paste some simple HTML to place any gadget on their own site. But why stop there? Dan from Uneasysilence dropped us a line about Mesa Dynamics, an interesting app company who has created two widget and gadget wrangling apps.First up is Amnesty Generator, a free utility that turns any Google gadget into a Mac OS X Dashboard widget. It sounds like one catch with this process, however, is that any gadget-cum-widget is 100% internet dependent, even if it's something like a standalone game. This makes sense to me though, since the HTML is still calling out somewhere to get whatever makes up the gadget widget.Second on the list from Mesa Dynamics is Amnesty Singles, which unleashes widgets from the Dashboard and turns them into full-blown apps. This utility costs $9.95 and requires Mac OS X 10.3.9 (though it's Universal), and I would imagine the internet dependence still exists for Google gadgets when turned into apps, though I would imagine Mac OS X Dashboard widgets which don't need the internet to begin with will act just fine without being online.So there's your time-waster for the day: gadgets to widgets to apps, oh my!
Japan Railway harvests passenger energy for fun and profit
The East Japan Railway Company is getting experimental with ways to make their train stations more environmentally friendly, and have turned to the warm bodies that fill their train seats for part of the solution. They've started installing ticket gates that generate electricity as people pass through them, harvesting the vibrations and pressure that results when people walk through the gates. It's not quite as nefarious as we were hoping for -- we think a bit of time chained to a stationary bicycle inside the train could do a commuter good -- but it still seems a pretty good idea, and we look forward to the results. Testing should last through August 11th, and most indications point to this being a fairly effective manner of getting electricity to where it's needed.[Via Pink Tentacle]
OLPC will be powered by pulling a string
We've been following Nicholas Negroponte's One Laptop Per Child initiative ever since the machine was still priced below $100, but once they jettisoned the hand crank, we've been wondering how they're going to deliver power to the 500MHz device. Enter Squid Labs, an R&D firm chock full of MIT Media Lab grads -- the same lab that Negroponte founded and ran for many years -- with an innovative human-powered generator that works by repeatedly tugging on a string in a motion similar to firing up a gas-powered lawnmower or snowblower. The team at Squid designed the external generator so that one minute of pulling yields ten minutes of computing, and included an electronic variable motor loading feature so that it can be operated by users of varying strength. Another nice feature of this system is that it can be configured in a number of different ways: users can either hold the device in one hand and pull the string with the other, or clamp it to a desk and operate the string with their legs. As long as further testing confirms the design's durability, and a better option doesn't come along, it looks like we'll be seeing classrooms full of string-pulling students when the laptop finally goes into mass production next year.[Via Slashdot]
