Technical Background

The technology is based on the open Brayton cycle, a four step thermodynamic cycle that creates power from a heat source, as follows:


– Adiabatic compression of the working fluid

– Isobaric heat addition to the working fluid

– Adiabatic expansion of the fluid through a turbine

– Isobaric heat rejection to the atmosphere


Both compression and expansion take place in rotating machinery.  In the implementation developed by Bluebox, the working fluid is air, the source of heat is a continuous waste heat stream, and the turbine drives a generator which creates electricity.
