Controlling the speed of a Stirling engine is problematic and poor throttle response is one of the key reasons this engine type has not seen use in automotive applications. In general, the Stirling engine has relatively large heat exchange surfaces and the engine's response to turning the heat input rate up or down is slow due to the need to ... small pond stream ideasWebStirling engine operation. Heat is transferred from the external heat source to the working fluid in the heater section, cyclicly stored and recovered in the regenerator, and rejected by the working fluid to the external heat sink in the cooler section. All of this is done in compact heat exchangers (large wetted area to void volume ratio) highlights hawaii

"Websubstance. The heat source can come from burning fossil fuels (such as gasoline), solar energy, decaying plant matter, or whatever is available [2]. In fact, all the Stirling engine requires to operate is a temperature difference. It is possible to run a Stirling engine by cooling one region of the engine below ambient temperature.
