Airborne Turbine for Remote Sites

Airborne Turbine for Remote Sites

Winds 300 to 600 metres above the ground are, on average 5 to 8 times as strong as those at the surface.

Altaeros, a four-year-old company in Massachusetts, has developed its Buoyant Airborne Turbine (BAT) to take advantage of these stronger, more consistent winds.  Read more »
