Reduction of external electricity requirement is mechanical system with flows of fluid or gas, uses recovery of energy from fluid flow to drive dynamo which charges accumulator

摘要

The device has four elements: a mechanical energy recuperator, a dynamo, an electric accumulator, and an electricity distributor. The recuperator (1) is placed in a gas flow and drives the dynamo. The dynamo (5) produces current which is stored in the accumulator (6). The distributor (8) connects to the external electric supply (7) if the accumulator cannot meet the load requirement.
