A thermal engine

[tamrock]

You never know what might show up in a TS. Priced at $14.95 plus tax and one like it on ebay completed sales that looked like it was missing the burner cover sold for $45. plus shipping. This one I bought looks like it was hardly ever touched. Found a YouTube of one in action

They are very cool! Sometimes you can find the engine, plus a machine that works off its power.
