The ERA-40 Project Plan

An engine, particularly adapted for use in automobiles, in which ambient air is compressed in a positive displacement compressor and then heated in a heat exchanger. The heat exchanger output drives a rotary turbine which, in turn, drives the positive displacement compressor and produces output power. Any source of heat, such as the combustion products from a fuel burning chamber, may be used to apply heat to the heat exchanger. A heat storage device is also incorporated into the system to provide power during sudden turbine demands.
