“High altitude winds have enough energy to power the Earth one hundred

times over.” Dr. Ken Caldeira, Stanford University Carnegie

Institution

Altaeros will provide low cost, flexible power to remote customers by

commercializing the first airborne wind turbine, using proven technology.

“In modern military use, aerostats are recognized as cost-effective, survivable systems capable of providing enhanced

ISR, communications and force protection capabilities to numerous operational scenarios.”
