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]
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.
Blow Light: the wind generated LED toy
While the message of living a greener life seems to be pounded into our ears on a regular basis, it's never too early to get your offspring in on the energy-conserving fun. The Blow Light toy from Nigel's Eco Store features a simplistic, kid-friendly design that's sure to require a lot of attention, as the miniature pinwheel doesn't light up and excite without a little effort on your youngster's behalf. The internal blue and green LED lights remain dormant until a gust of wind (or hot air) starts the spinning, subsequently lighting up the device and eliciting smiles all around. Of course, with no batteries required, the price on this uber-green toy tends to be a bit higher than the mass market alternatives, but at least your £9.99 ($20) won't be fueling the proverbial fire.[Via Inhabitat]
Micro-turbines output micro-electricity for Hong Kong's micro-apartments
It's not just the fitness club types in Hong Kong attempting to generate a bit of renewable energy, inventor Lucien Gambarota -- the very man responsible for converting all that cardio into voltage -- is showing off some micro-wind turbines for even more power bill relief. There's currently only a single wind turbine on a small outer island providing energy to Hong Kong, the rest of the city just doesn't get enough wind for traditional turbines to do any good. Not so with Gambarota's new micro-turbines, which can generate electricity with as little as 2 mph of wind, and keep turning at all times from the slightest of breezes. The little windmills are actually gearwheels, mounted in a array. They can be arranged in different shapes and sizes, from two to thousands of square meters. The energy is put into a battery, which then powers appliances in the building. Currently the micro-turbines go for about $25 for a set of 20 gearwheels, but that price should drop considerably once they begin to be mass produced.[Thanks, nvyseal]
Quiet Revolution's QR5 addresses wind turbine issues
If you ask a person on the street what they think about wind turbines in general terms then the reaction will in most cases be favorable. Ask what they think if someone was about to place wind turbines within direct sight of their home, and the response probably won't be one of glee. Common concerns often include the whooshing sound that regular turbines produce, as well as their divisive visual aesthetics -- some love it, some loath it. A new type of wind turbine intended to address both of these issues is Quiet Revolution's QR5 Vertical Axis Wind Turbine, or VAWT for shawt. The QR5 is smaller, quieter, and way better looking than your typical windmill, plus it should produce the equivalent of its £25,000 price tag in clean energy within 15 years or less. We're down with the futuristic design and the company's noble aims, but we feel that the QR guys should spice up the name of this particular turbine. Our suggestion? Pigeon Dicer, Mark 5.
MIT's new "invisible" wind turbines float offshore
Thanks to MIT's Paul D. Sclavounos, we might get a reprieve from the eyesore problem of windmills, while still sticking with their clean-and-cheap energy benefits. Unfortunately, hapless birds aren't going to get much of a respite. The plan is to plant these things offshore, far enough out into the water for the skinny white turbines to disappear on the horizon, but we're sure a few seagulls will be able to find those "invisible" blades all the same. The turbines can be anchored in water up to 650 deep, and can withstand even hurricane-generated waves. Another benefit of the system is the strong and steady wind out at sea, so the 90-meter turbines should be able to generate twice as much electricity in comparison to their near-shore counterparts. Count us in, we never liked seagulls too much anyways.
