Floating wind turbines bring electricity where it's needed

09.02.2015 | |

It's a balloon that lifts a wind turbine. That's the easiest way to describe the technology being developed by Altaeros Energies, led by Ben Glass, inventor and CEO of the young company. Glass has reimagined the possibilities of balloon and airship technology to lift a wind turbine

Most wind turbine manufacturers are competing to build taller turbines to harness more powerful winds above 500 feet, or 150 meters. Altaeros is going much higher with their novel Buoyant Airborne Turbine—the BAT. The Altaeros BAT can reach 2,000 feet, or 600 meters.

At this altitude, wind speeds are faster and have five to eight times greater power density. As a result, the BAT can generate more than twice the energy of a similarly rated tower-mounted turbine.
