Measure the power and efficiency of your Stirling Engine

Science

Doug Conner of Atascadero, CA wrote in with his technique for testing Stirling Engines.

I’m running this engine from the heat of a 70W light bulb in the video, but It also runs well from the heat of two candles. Using higher heat sources it puts out over 1.5 watts. I need to redesign the engine so that it can run faster than the current limit of about 240 rpm to achieve higher power.

    Atch, thanks for the catch, Stefan!

    I love Stirling engines because they are simple enough that you can build them out of junk but still power them off of anything that creates a temperature difference. I’m going to have to see the YouTube comments to find out how many people begged for plans.
