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?

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.

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.

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?

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.

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.

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.

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.

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.

Forget biodiesel and fuel cell-powered vehicles, how about a whip that doesn't require any fuel whatsoever? The Venturi Eclectic, touted as an "autonomous energy vehicle," gets its charge from wind gusts and 8.2 square feet of solar cells atop its roof. The four-person ride boasts a 22-horsepower purely electric engine, is powered by liquid-cooled NiMH batteries, and can reach a (yawn-inducing) top-end speed of nearly 32mph. While it's no Wrightspeed X1, the designers had "daily driver" in mind when the Ecletic was crafted, but considering it'll only roll 31 miles on a full charge, you best take the scenic (read: sunny) route to work if you're facing a long commute. The car does sport an option to recharge via AC power, should you face darker (and calmer) than expected conditions, but since it weighs just 772 pounds, a foursome shouldn't have too much trouble using the tried and true "push method" if worse comes to worst. Scheduled for production in June 2007, this oh-so-green automombile will run you €24,000 ($30,511) -- if you can manage to score one of the 200 that'll be built, that is.
