This wind turbine which is designed to float in the air at a high altitude is meant to provide a small amount of power. The idea behind it is to bring sustainable power to remote areas or places where conventional wind turbines can’t be built.
The BAT uses a helium-filled, inflatable shell to lift to high altitudes where winds are stronger and more consistent than those reached by traditional tower-mounted turbines. High strength tethers hold the BAT steady and send electricity down to the ground. The lifting technology is adapted from aerostats, industrial cousins of blimps, which have lifted heavy communications equipment into the air for decades.
