A blimp-turbine to harness high-altitude winds

by
in ask on (#2T1E)
Think of it as a Goodyear blimp for the era of alternative power. A kind of giant tubular helium balloon with a three-bladed turbine inside, floating as much as 2,000 feet in the air so it can capture energy from winds that blow stronger and more steadily than they do at ground level. The system is designed to deliver energy to a ground station via one of the cables that would tether the balloon to Earth. It could be inflated, tethered to a ground station built on a trailer platform, then deflated and moved.

With the aid of a $740,000 grant from the Alaska Energy Authority — which is interested in power sources for the state’s many communities that are off the electrical grid — Altaeros is working on a commercial BAT that will house a 30-kilowatt turbine, which could power about a dozen homes. Later versions, Rein said, would be 200-kilowatt models, big enough to compete with generators that typically power remote mines and construction sites. “We’re not trying to replace wind turbines,” Rein says. “We’re trying to expand wind energy to places where it doesn’t work today.”
