Abstract: A hybrid energy conversion system comprising a sun concentrator, a radiation-to-heat exchanger arranged in a radiation chamber and configured to receive high density sun radiation from the sun concentrator through an entrance of the radiation chamber, a Stirling engine operable to convert heat from the radiation-to-heat exchanger into mechanical energy, and a burner configured to generate combustion energy for operation of the Stirling engine by combustion of a suitable fuel. The combustion chamber has an exhaust outlet for removal of combustion gases from the chamber, which exhaust outlet is arranged to create a flow of combustion gas from the entrance past a front portion of the radiation-heat-exchanger. By creating a flow of combustion gas past a front part of the radiation-to-heat-exchanger (i.e. a part facing the entrance of the radiation chamber), energy transfer by heat convection is improved.
