An environmental control system which is particularly suitable for use in aircraft comprises an air compressor (22) and an expansion turbine (36). The air compressor (22) is electrically driven at its optimum speed to deliver compressed air to the turbine (36). The compressed air expands through the turbine (36), thereby reducing in temperature as it drives the turbine (36). An electrical generator (44) is driven by the turbine (36). A condenser (33) is provided to condense water vapor in the air exhausted from the compressor (22).

[ What is claimed is:] [1.]1. An environmental control system comprising an air compressor, an electric motor to drive said air compressor, an electrical power control and distribution system to receive electrical power and to direct at least some of that electrical power to drive said electric motor, a turbine to receive and expand air delivered thereto by said compressor to thereby cool said air, an electrical generator driven by said turbine, said electrical generator providing at least some of the electrical power received by said electrical power control system, and a water separator to remove water from air exhausted from said compressor.
