Abstract

This invention provides an apparatus and method for generating rotary power, the apparatus comprising a heat exchanger arranged to receive heat from a heat source to which, in use, the apparatus is connected and to transfer heat to a working fluid at high pressure; and, an expander comprising a low friction displacement device for receiving a metered amount of the heated high-pressure working fluid and for retrieving energy from the working fluid by being driven by the heated expanding working fluid.
