"Has anybody tried to combine several engines like this on the line (3-6 cylinder...) to see, if the efficiency could be preserved so that a real home made power station could be developed?"


I saw a triple version of Dr. Senft's Moriya at the Lake Itasca Region Pioneer Farmers Show several years back. It did not appear to generate a significant amount of power. Maybe too much friction?

At that time they has a building dedicated to hot air engines. Some of the engines probably weighed close to a ton. One Man, Olaf Berge, would bring his collection of full size engines. He and his wife would have them all operating for the whole weekend. Incidentally that show is one of the best I have been to. The 600 mile trip just got to be too much for me to drive now, plus my grand-kids are all grown-up so I would be going by myself..
