Hot water Stirling engine success!
Finally I got my Sirling engine to run on a cup of hot water. It was 2 am in the morning and the air temp was 65 degrees in my house. I also show this running on heat stored in a piece of aluminum that was warmed up on the stove. These engines only need a heat differential to run —-they don’t care how or where it came from. That is a beautiful idea.
