    Looking for power in hard to reach places? Perhaps M2E Power can lend a hand. The company -- recently infused with a pile of money from venture capitalists -- is in the business of creating power through the kinetic motion of everyday human and / or mechanical movement. The idea is that by simply walking or driving, energy can be produced that will power devices on-hand, obviating the use of outside sources -- an idea that will be of particular use to soldiers on duty, as the technology could reduce their load by up to 30-pounds. The devices also contribute to efforts towards clean power and extended mobility on the consumer side, efforts your DS-playing kids will go bonkers for. For those down with the Faraday Principle (energy produced via motion of a magnet through a wire coil), you'll be happy to know that someone is putting the concept to good use -- for the rest of us, well, we'll just be happy if we can get a few more minutes out of our mobile phones.

    I think we somehow missed this at TUAW, but I have no idea how. Just in time for everyone to head home for the holidays (and forget their iPod chargers), here's a quick fix solution to get that battery back up and you back listening to The Cars' Greatest Hits. Household Hacker put this together, and unfortunately they say on the same page that you should not attempt this at home if you're not an expert, but all of you TUAW-reading iPod owners out there are experts, right? If you do try this, don't hurt yourselves or your iPods.How does it work? Beats us-- the electrolytes in the Gatorade might be breaking down the individual cells of the onion, and releasing excess energy as electricity of some kind, but obviously that's just a guess based on my many years of watching Bill Nye, Beakman's World, and more recently, Mythbusters (pop science for the win!).There is one major problem with this plan, however, and that is that as of right now, onions do not properly install updated firmware for any iPods of any generation. Hopefully, Apple will fix this oversight in the next Software Update.

    We've seen a plethora of shirts made for more than just satisfying a core necessity in life, but a team of scientists over at the CSIRO's Energy Technology Division are hoping to have "power shirts" at your local flea market (or other fine establishments) within five years. By using piezo electrical materials, the garb could reportedly "produce electricity as you move," enabling users to juice up their DAPs, mobiles and air conditioned pants just by staying active. Other potential applications include powering battlefield-related equipment on soldiers and monitoring systems on the elderly, but making sure it can handle the oh-so-intimidating wash cycle remains a challenge.

    Ever wonder if you could tap the electrical current on your phone company's landlines (does anyone still use those anymore?) to supply low-powered household gadgets with juice in an emergency (or financial pinch)? Turns out that apparently it ain't too hard to get between 40 and 70 volts (no word on wattage) with a few components and a little time spent soldering. Now comes the second, more PSA-style half of this post. How ridiculously guilty might you feel if a power outage occurred and people couldn't call for help because enough nerds trying to save a buck by charging their gadgets via landline took out the phone company. Sure, it's a dramatic scenario, but we're just saying it's also potentially dangerous, so use this technique wisely.

    We've seen some fairly impressive uses of wind power, but a group in Iowa is looking to actually capture and preserve excess wind energy for use when demand peaks. At the Iowa Stored Energy Park, a number of local utilities is "building a system that will steer surplus electricity generated by a nearby wind farm to a big air compressor," which will be held deep below the ground for future use. The project is being backed by the Energy Department, but more than a hundred municipal utilities in surrounding states are shelling out $200 million to construct the 268-megawatt system. As it stands, Iowa's compressed air energy storage (CAES) installation will be the first of its kind when it's completed in 2011, but there's already work being done in Texas to build a similar unit.[Via Ecotality]

    We've certainly seen instances of intrabody communications at work, but now NTT DoCoMo is looking to join the fun and hopefully tie cellphones into the equation. Apparently, the firm has "various devices" in development that could utilize an "advanced handset" in certain forms of wearable electronics to give users the ability to unlock doors, make payments and exchange data with a friend with a simple touch. The prototype mobile packs a sensor produced by Kaiser Technology Company, and while the current version can only transmit data at 40-kilobytes per second, a speedier flavor is surely on the horizon.

    We're all for conserving electricity and all, but preventing every one of your AC outlets from actually passing energy onto your favorite gizmo is indeed extreme. Nevertheless, we can't help but be impressed with the variety of Die Electric insulators, which take on a plethora of shapes to not only prevent your outlets from actually passing electricity onward, but double as helpful household accessories (or just plain weird wall adornments). Of course, any halfway industrious individual could probably concoct their own Die Electric, but if you must go straight to the source, prototypes are available for sale now.

    Apparently, Marine Current Turbines is having quite the time trying to install what would be "the world's largest tidal power project," as the installation that was slated to begin Monday will now be lucky to see completion this year. Dubbed SeaGen, the project will reportedly utilize "twin underwater turbines to generate 1.2-megawatts of electricity off the coast of Northern Ireland," which are said to "look and work very much like wind powered [alternatives]." Notably, the company even mentioned that the devices spin "too slowly to affect marine life," and just in case you're concerned about its future plans, it "intends to eventually build farms of turbines consisting of 10 to 20 pairs each."

  • Man-made 'tethered tornadoes' touted as a viable power source

    With all the wacky unconventional proposals we've seen people come up with for generating electricity in an environmentally friendly manner, is it really so outrageous to think that giant, man-made tornadoes could be harnessed to power a small city? Well that's exactly the idea being floated around the University of Western Ontario these days, which is currently testing a scale model of retired refinery engineer Louis Michaud's patented vortex engine -- a machine fueled by excess power plant heat that uses the physics of convection inherent in rising air to drive electricity-producing turbines. In its most grandiose realization, the engine (inventor's rendition pictured above) would be 200 meters in diameter and generate a 'clean' (debris-free) tornado stretching 20 kilometers into the sky able to coax 20 megawatts each out of ten independent turbines. Obviously the main concern about the anticipated $60 million project -- which would reportedly operate at just a quarter of the cost of a coal-based facility, even before taking into account the $20 million saved on a cooling tower by the participating power plant -- is that the tornado could somehow escape its confines and wreak havoc on nearby communities. Still, with all the advantages this scheme seems to offer, we're certainly willing to give it a chance -- after all, a 'malfunctioning vortex engine' is a lot less scary than a potential disaster at one of the many nuke plants dotting our landscape.[Via UberReview]

    From a kid's perspective, we're sure they'd much rather be cruising on the iPod-equipped bus than a vanilla version that gets significantly better mileage, but regardless, a Tampa Bay school will become the first to receive a pair of hybrid buses to shuttle students around while saving between 70 and 100-percent in fuel costs. The vehicles can be fully charged in around six hours, and while the aforementioned improvements are only so drastic for the first "50 miles or so," it's certainly not a bad start. 'Course, school district officials are hoping that fuel savings will eventually lead to more money for classroom improvements, but we reckon it'll be quite some time before the savings on fuel overtakes the up front cost of these (presumably pricey) machines.

    If being able to recharge your future collection of batteries "a thousand times more" than your existing stockpile sounds enticing, a team of NC State physicists now have your attention. Thanks to their research on the electromechanical properties of the commonly used polymer polyvinylidene fluoride (PVDF), they have discovered that when combined with CTFE (that's yet another polymer), it may allow capacitors to store "up to seven times more energy than those currently in use." According to Vivek Ranjan, the process moves atoms within the material "in order to make the polymer rearrange with the least voltage," and this storage booster could even be used to allow electric cars of the future to sport the "same acceleration capability as a gas-powered sports car." Sounds like more than a few manufacturers are desperate for something like this, eh?[Image courtesy of Biopact]

    We'll go ahead and hand it to Spectrolab for crafting such an immensely efficient solar cell without regard to cost, but a team of Korean researchers have reportedly conjured up a rendition of their own that, you know, would actually be feasible to commercialize in the not too distant future. The team -- led by Lee Kwang-hee of the Gwangju Institute of Science and Technology -- has reportedly created a diminutive plastic solar cell that touts "6.5-percent efficiency," and while that number pales in comparison to other alternatives, it's the pricetag that's of interest here. Apparently, existing solar cells that use silicon semiconductors cost around "$2.30 to generate one watt of electricity," whereas this group's solution costs just ten cents per watt. Better yet, plans are already in motion to increase efficiency up to 15-percent, after which we could see these things hitting the marketplace at large "by 2012."

  • Eubiq's power track system trumps extension cord

    Eubiq's power track system is far from the first unique take on providing power elegantly to an array of devices, but we've got to give props to the unobtrusiveness this installation provides. The system can be mounted along essentially any wall in your domicile, garage, or office, and since juice is constantly flowing through the track, you simply plug in a proprietary adapter, twist, and enjoy your newfound current. Of course, if you're looking to use generally accepted plugs in your country, you'll have to pony up for adapters in order to make it worthwhile. Currently, Eubiq's not handing over any pricing details for you to inspect, but we can imagine that this here system will likely be reserved for the power-hungry and / or affluent sects whenever it lands.[Via Wired]

  • Australian develops diminutive wind turbine for household energy

    Generally speaking, wind turbines have been reserved for more macro-scale operations, but a West Australian inventor "believes he has developed a way to generate electricity for homes using wind power." This residential approach utilizes a modular turbine that is minuscule enough to perch atop nearly any roof without causing too much unsightliness, and can create power for the house to consume as the wind pushes its blades. Additionally, Graeme Attey suggests that solar panels could be used in conjunction with his creation, giving you double the renewable energy opportunities (at least during the day). Currently, Mr. Attey's device is being partially funded by the West Australian government, and homeowners who toss one up on their crib could receive a rebate if in fact this is ready for commercialization next year.[Thanks, Strayan]

  • Hydrogen separator could power fuel cells from city gas

    We've seen power hacks that allow hybrid vehicles to energize your domicile, but even that isn't enough to change how entire cities receive electricity. Now, however, the Japan Fine Ceramics Center (JFCC) has collaborated with Noritake Co. and a few other firms to develop "a high-performance hydrogen separation membrane made from ceramic materials" that can purportedly "attach directly to a gas pipeline to supply hydrogen for fuel cells using city gas as the source." Additionally, the the reaction to generate hydrogen can be carried out at a temperature of around "300-degrees lower than normal," and while current estimations are suggesting that cities won't be powered via this method until closer to 2020, there's always the option for a gigantic solar field to fill the void in the time being.

  • Designer dreams big with uber-green Twirling Tower

    While the architectural playground that is Dubai isn't running low on innovative buildings, David Fisher is hoping to add yet another skyscraper to the mix with his self-sufficient and energy generating Twirling Tower. The 68-story "combination hotel, apartment, and office" would sport floors that each rotate 360-degrees in the span of about 90 minutes, creating a "constantly changing architectural form." His claims begin to elicit suspicion, however, when a promotional video (seen after the break) for the building claims that it can snag enough wind to not only power the building itself, but to energize ten other similar buildings just like it. Of course, we aren't taking that too seriously considering that he actually mentions that supplying electricity to the floors would be "similar to how a moving train captures power by staying in constant contact with a power source, like an overheard wire or third rail." Nevertheless, Mr. Fisher sure seems determined to get this thing up in the sky, but as with most big dreams in Dubai, moving beyond the drawing board is where things get tough. [Via Inhabitat]

    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]

    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]

    Just last month we witnessed a gigantic skyscraper / solar tower hybrid that generates a whopping 390-kilowatts of energy, but even that looks like child's play compared to the 40-story solar power plant that resides in Spain. The expansive system consists of a towering concrete building, a field of 600 (and growing) sun-tracking mirrors that are each 120-square meters in size, and a receiver that converts concentrated solar energy from the heliostats into steam that eventually drives the turbines. Currently, only one field of mirrors is up and running, but even that produces enough power to energize 6,000 homes, and the creators are hoping to see the entire population of Seville (600,000 folks) taken care of solely from sunlight. So if you're eager to see what's likely the greenest solar power plant currently operating, be sure to slip on some shades, tag the read link, and peep the video.[Via Wired]

    While it's certainly debatable whether beer is to thank for the explosion in the consumer electronics industry, it looks like we'll be thanking the beverage without hesitation for making our world a little greener. Oddly enough, "scientists and Australian beer maker Foster's are teaming up to generate clean energy from brewery waste water by using sugar-consuming bacteria," and better yet, the University of Queensland will host a microbial fuel cell at a Foster's Group brewery near Brisbane. Essentially, the cell will consume brewery wastes such as sugar, starch, and alcohol, while producing clean electricity by harnessing the energy released from the organic materials coming in. The device is expected to produce two-kilowatts of power, and while hopes are to bring the technology to other breweries and wineries around the country, this iteration should crank up sometime in September.[Via Physorg, thanks Michael T.]
