Altaeros Energies is developing a breakthrough airborne wind turbine to produce abundant, low cost, renewable energy. These turbines are extremely efficient. This video of a tethered blimp prototype harvesting energy at 350 feet is the proof of concept.
The prototype was tested in Limestone Maine by Altaeros Energies, a wind energy company formed out of MIT. The Airborne Wind Turbine uses a helium-filled, inflatable shell to ascend to higher altitudes where winds are more consistent and over five times stronger than those reached by traditional tower-mounted turbines. The automated lifting technology is adapted from aerostats, industrial cousins of passenger blimps that for decades have lifted heavy communications and radar equipment into the air for long periods of time. Altaeros is developing its first product to reduce energy costs by up to 65 percent by displacing expensive fuel used to power diesel generators at remote industrial, military, and village sites
