New wind turbines at least 30% more efficient, Earth one step closer to salvation
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?
