Behold the BAT (Bouyant Air Turbine) – a helium filled dirigible that deploys 300m (1000ft) above ground, generating low-cost energy for microgrids (ie. remote/island communities, disaster relief areas and military bases.)
A modern cousin of the blimp, the BAT, created by MIT founded company Altaeros Energies, is an aerostat – a heavy duty inflatable designed to withstand hurricane winds. High tensile tethers hold the BAT steady at high altitudes where winds are stronger, feeding power down to the ground.
