Dutch scientists develop kite power system with enough juice for 10 homes
Sure, the Netherlands might be known for its windmills, but a group of scientists at the Delft University of Technology is aiming to harness the wind in a different way: by using kites to generate electricity. A recent test generated 10 kilowatts, or enough juice to power 10 homes, and the plan is to eventually send an array of kites called the Laddermill up to 30,000 feet in order to generate nearly 10 megawatts of power. Of course, that's all in the future -- for now, we've just got two dudes, a kite, and a pretty dry video after the break.[Via Inhabitat]
Texas wind power initiative to blow other states away
Oh sure, Rock Port, Missouri managed to snag the title of being "100% wind powered," but Texas' new plan will make the Show Me state's gusty initiatives look awfully weak. Officials at the Public Utility Commission recently okayed a plan to "build billions of dollars worth of new transmission lines to bring pollution-free energy from West Texas to urban areas." The ginormous Lone Star state is already the nation's leader in wind power, but when said plan is fully implemented (pending final approval), it'll produce more wind energy than the next closest 14 states combined. Granted, customers will be paying a touch more ($4 per month is the current estimate) for all this clean energy, but pundits assert that the cost is minor when looking at just how much this will help out Mother Earth. Look for everything to go live in four to five years, barring any unforeseen setbacks.[Thanks, Adam]
Ricoh erecting 47 x 126-foot solar and wind-powered billboard in Times Square
Ever walk through Times Square and wonder how much electricity all those flashy billboards are soaking up? No? Well, Ricoh has, and now they're doing something about it. Ricoh Company Ltd. of Tokyo is erecting a 47 x 126-foot billboard at Seventh Avenue and 42nd Street that will be completely powered by the sun and wind. Fueled by 45 solar panels and four wind turbines, the billboard won't even need a backup electric generator. On days that the sun and wind aren't enough to power it, it will simply go dark. In the end, the billboard is said to reduce carbon dioxide usage by 18 tons a year. The billboard will go live in December, or just in time for the sun to go dark.
Philippe Starck shows off "Democratic Ecology" wind turbine
It looks like wind power is about to get a bit more stylish with the outspoken Philippe Starck now wading into things with his "Democratic Ecology" personal wind turbine. The turbine first made its debut at the recent Greenenergy Design show in Milan and, according to Inhabitat, it's now on track for an actual release in September of this year, thanks to a little assistance from Pramac. If all goes as planned, the turbine will set you back about €400 (or just over $600), and provide anywhere from 20% to 60% of the energy need to power an average home, although you'll presumably need some additional equipment to go along with the turbine.
Uniross rolls out new range of eco-friendly battery chargers
Uniross has already done its part to make batteries slightly more environmentally-friendly, and it now looks like the company is giving a boost to the other end of the equation as well, with it introducing a new range of eco-minded battery chargers. That includes a £40 ($80) solar charger with a USB adapter (pictured above), as well as a £50 (or $100) wind power charger (also above), which comes complete with a bike mount and an integrated lithium ion battery, as well as a USB adapter and ports to charge your cellphone or handheld game console. Those get complemented by a couple of more standard devices, including a 15-minute battery charger, the NOMAD "portable power hub" with a USB adaptor, and a travel clock charger, which packs an alarm clock and promises to charge batteries in less than three hours. Look for the whole lot to be available in August, with those last few setting you back £35, £20, and £30, respectively (or about $70, $40, and $60).
Offshore wind power park to energize Delaware homes
Unlike Rock Port, Missouri, the entire state of Delaware won't be 100-percent wind-powered after Bluewater Wind constructs a $1.6 billion wind park just off its shore, but the state will be able to "light about 50,000 homes a year" for the duration of the 25-year contract. Said agreement was just nailed down between the aforesaid firm and Delmarva Power, and it hopes to start powering homes via wind by 2012. The offshore site will sit around 12 miles off Rehoboth Beach, with a number of turbines to be planted 90-feet into the sea floor and sport three blades apiece measuring 150-feet long. It's noted that vacationers and locals alike won't be able to notice the park from the beach except on a few remarkably clear days, but if their energy bills sink because of it, we don't really think they'll mind, anyway.
Orange's recharge Pod tent to keep mobiles juiced at Glastonbury
For those fortunate enough to be planning a trip to this year's Glastonbury, you can rest assured that forgetting your mobile charger won't be the worst thing that could possibly happen. Reportedly, Orange will erect a seven-meter high recharge Pod tent in which patrons can stop by and reinvigorate their winded handset. Said tent will boast 500-watt solar panels and a 500-watt wind turbine in order to generate electricity for the lifeless phones, and Orange is hoping to juice up 100 devices per hour. If only such conveniences were everywhere...[Thanks, Adam]
Rock Port, Missouri celebrates being "100% wind powered"
We've seen a number of locales pipe in quite a bit of energy from eco-friendly sources, but the community of Rock Port, Missouri is claiming to be 100-percent wind-powered. The gloating is due to four wind turbines erected on agricultural lands within the Rock Port city limits, and while the town is expected to consume around 13 million kilowatt hours of electricity this year, the aforesaid turbines will produce 16 million kilowatt hours. Excess energy generated will be pridefully sent out for purchase by the Missouri Joint Municipal Utilities, where it will eventually be consumed in less thoughtful areas. Of course, the town has been operating in such a manner for a small tick now, but it just recently found the energy to throw a party for itself to commemorate the accomplishment. Can we get an invite next year or something?[Thanks, Yossi]Read - Rock Port releaseRead - Rock Port video
Oilman T. Boone Pickens drops $2 billion on wind power
It looks like wind power in the United States is getting a boost from a somewhat unexpected source, with billionaire oilman T. Boone Pickens recently announcing that he's spending $2 billion to build a 667 wind turbine-strong wind farm in Texas. That would translate to roughly 1,000 megawatts of electricity, or enough to power about 300,000 homes, but Pickens says that is only the start of what he has in mind. As he tells CNN, Pickens says he plans to expand the wind farm to a full 4,000 megawatts by 2015, which would likely make it the biggest wind farm in the world. What's more, in addition to pumping out electricity, the wind turbines would give a boost to the pocketbooks of anyone willing to put 'em on their property, with Pickens estimating that each turbine will generate about $20,000 a year in royalty income, although they apparently won't get electricity straight from the turbine in their backyard.Read - CNN, "Billionaire oilman backs wind power"Read - Reuters, "T.

Superpowerful small wind turbines light up the night
We've seem some impressive wind power tech, but a new breed of small, high-power wind turbines could potentially bring efficient wind power home. Developed by an inventor named Doug Selsam, the new turbines have rotors just 14-18 inches in diameter, but can produce 200 watts in a 20MPH wind, and much more than that at higher wind speeds. The trick is using high-strength carbon-fiber materials that allow several rotors to be hooked up as one -- in strong winds a thirteen-rotor system can produce enough juice to blow out a bank of car headlights "like flashbulbs." That's pretty impressive -- especially since the system is light and balanced enough to be held up with one hand. No word on when or how we might see these hit the public, but we can see some pretty sweet applications -- laptops in the park, anyone?[Thanks, Yocheved]
Magenn gets its MARS floating wind turbine off the ground
We've already seen some wind turbines designed to float offshore, but Canadian startup Magenn Power has some ideas of its own for getting wind power off the ground and, judging by its latest tests, it seems to be making some considerable progress. Its solution, dubbed the Magenn Air Rotor System (or MARS), is designed to float between 600 and 1,000 feet above the ground, and spin on the horizontal axis to generate electricity, giving it a power capacity of anywhere from 10 kilowatts to several megawatts depending on the configuration. While they've apparently yet to extract any juice from it, the company has at least recently gotten a prototype off the ground at a massive airship testing facility in North Carolina, and it has apparently now set its sights on an outdoor test, although there's no word as to when that might go down. What's more, as Greentech Media reports, while the company apparently plans to first market a 100 kilowatt version for industrial use, it also hopes to eventually enter the consumer market with smaller models that people "can take camping or use at their cottage," although it admits that prospect has been put on the backburner for now.[Via Protein]
Pinwheel and old VCR used to make wind-powered LED
Now that Blu-ray has emerged as the lone HDM victor, that aging VCR is likely looking for a new home (if it wasn't already). Thankfully, we've found the perfect excuse to rip it wide open versus hauling it off to the local thrift store. In one of the more elaborate how-to guides that we've seen, Charles Palen explains how to create a wind-powered LED by using scrap parts within a VCR, one your youngster's pinwheels and a varied array of power tools, wiring and calm nerves. Notably, an unwanted CD-ROM drive can be used if you're dead set on watching those Disney classics on VHS one last time, but regardless of which apparatus you destroy, be sure and hit the read link for the step-by-step.[Via instructables]
Danish wind turbine eats itself
You know how we love wind turbines around here, but we love carnage even more -- so we can't get enough of this 200-foot tall Danish wind turbine shearing itself to bits after its brakes failed during a recent storm. The 10-year old windmill is the one of two different Vestas windmills to fail in Denmark in the past week -- the company is launching an investigation, but might we suggest selling tickets instead?[Via BoingBoing]
HYmini alternative power source specs and pricing revealed
Upstart MINIWIZ managed to attract our attention with its HYmini alternative power source last fall, but it unfortunately didn't have all the specs we could have asked for or, more importantly, a price. In case you missed it, the HYmini device itself makes use of wind power to recharge the integrated battery, which in turn can be used to charge your various gadgets. If wind's not an option, however, you can also make use of the optional solar panel, or simply plug it into an outlet and power it up the old fashioned way. As MINIWIZ has now revealed, the device also comes with five different connectors to accommodate most anything in your gadget bag, and you'll be able to snag a bike or armband kit to make full use of that wind power. If that sounds like what you've been waiting for, you can grab the basic HYmini package now for $50, with the solar panel running an extra $25 and the bike and armband kits demanding $9 and $15, respectively.[Via SlashGear]
Maglev wind turbines 1000x more efficient than normal windmills
We've seen a couple innovative wind power solutions pop up, but none that claim to offer the benefits of maglev wind turbines, which use full-permanent magnets to nearly eliminate friction by "floating" the blades above the base. According to developers, the technology is capable of scaling to massive sizes, with a proposed $53M turbine able enough to replace 1000 traditional windmills and power 750 thousand homes. Additional benefits include the ability to generate power with winds as slow as three miles per hour, operational costs some 50 percent cheaper than windmills, and an estimated lifespan of 500 years. That all sounds great, but the real proof will come when these things get put to use, which may happen sooner than you'd think: Development is proceeding rapidly in both the US and China, with Chinese power company Zhongke Hengyuan Energy Technology currently building a $5M factory to produce the turbines in capacities from 400 to 5,000 watts.
Loopwing toy car runs on wind power
We're big fans of both alt-power and silly toys, so Tamiya's latest kitcar, the Loopwing, pushes all our geek buttons. The build-it-yourself kit car comes with its own windmill, and five minutes of charging in a five mile wind powers the three-wheeled racer for three and a half minutes. We have fond memories of building a Tamiya RC10 kit when we were kids -- hopefully the $30 Loopwing will inspire kids to think about windpower the same way our kit inspired us to think about taking apart everything we owned.[Via TokyoMango]
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]
Orange hopes to harness the wind to charge your mobile
With O2's recent green move, it seems Orange has cried "me too" and hopped on the enviro-friendly train. The Orange commissioned turbine -- which will be unveiled at the Glastonbury festival this week -- weighs just 150 grams and can be mounted on a tent where it will spin and charge some type of battery pack. Once your day of hard trekking is done, simply plug your mobile into the device, and voila, instant power while far from home. While we are fairly confident that O2 just looked for something to let them into the sponsorship inner circle at the Glastonbury Festival, that doesn't stop us from wanting one -- but make ours hat-mounted, thanks.[Via textually.org]
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]
Proposals would turn highways into wind farms
Clogged highways and frustratingly waiting while your gas needle plummets to empty usually doesn't conjure up thoughts of green, but it seems like these very roads could become the source of a lot more energy. Several recent student designs have proposed that major roadways be retrofitted with various forms of wind energy collection devices, ranging from overhead turbines that collect energy from quickly-moving cars below to barrier panels (pictured after the jump) that harness the wind from closely passing vehicles moving in opposite directions. Ideally, the wind energy could then be sent back out to the grid to power nearby communities, light-rail transportation systems, or even intelligent billboards. Of course, most of these ideas are still in the research phase, and even if proven feasible, we can't imagine the up-front costs (or inconveniences of installing these things) to be minor, but we're sure that government subsidies should be able to to lend a helping hand.Read - Barrier panel prototype, via InhabitatRead - Overhead turbine design, via Inhabitat
