But you must admit that an 80m (~262ft or ~24 stories) wind turbine blasting off like a giant pogo stick into the sky is by far the most comical.<p>Maybe gravitational doesn&#x27;t make sense, but compressed air might. Big compressor directly driven by the turbine (so as not to waste energy converting to electricity to turn an electric compressor motor) being used to compress normal air into large tanks inside the wind turbine tower which can later be used to spin another turbine-based generator using the same air. Not a physics major, but this seems feasible. Not sure of the potential energy storage, but I feel like the direct conversion of rotational energy to spin the pump has to be much more efficient than converting it to electricity first, then using that [many miles away] to compress air or drive a train up a mountain.
