The world spends trillions of dollars to produce heat, but how much of this heat do you think we waste? According to the U.S. Department of Energy, 58%.  The Barton engine is a unique combination of high efficiency at low scale, using standard, low cost materials combined with the versatility of one or many external (waste) heat sources.

(Landfill, Waste water treatment)

(Burn-off, incinerators, pyrolysis)
Solar Thermal
500°C+ waste heat from the exhaust of internal combustion – gas turbine or reciprocating engines, or diesel generators
Exothermic chemical reactions
