Still addicted to oil like the rest of the world? You might reconsider wind power rehab now that a startup called ExRo has developed turbines that it says are consistently 30% -- and in some situations as much as 100% -- more efficient than the standard kind. The traditionally-used mechanical transmissions have been replaced with an inexpensive electric alternative that can adapt to changes in wind speed more efficiently. Also, many small generators are used instead of a large one, so the turbines can be customized in production to suit the intended installation site. If this is the real deal, it beats the 0.1% increase we saw in solar cell efficiency a few months ago, and those Maglev uber-turbines are still on the horizon. Hey Sun -- jealous yet?

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?
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.
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.
