Clever design, perhaps. However, it only applies to small, residential AC. Commercial systems use more efficient designs already, such as screw compressors. Als

Clever design, perhaps. However, it only applies to small, residential AC. Commercial systems use more efficient designs already, such as screw compressors. Also, good luck using this with a turbine - many of the largest compressors directly driven by gas or steam turbines, which are way more efficient than electric motors because they eliminate inefficiencies associated with electric generation and distribution.
