Stirling Engine Refrigerator—-Failed 1st attempt
Here I try to turn my Simple Free Piston Stirling engine into a refrigerator heat pump by driving it backward with an electromagnet and an oscillator circuit. It didn’t work.
Here is a link to a homemade Beta Stirling made by Approtechie that is being run as a refrigeration unit. It is non-pressurized and uses only air as the gas. This is what I am going after.
