Flame Gulper Engine

This Flame Gulper Engine was made from plans in the February 1950 issue of Popular Science. The fuel is alcohol. Modifications were made to replace the castings originally specified. This is a video of the flame gulper engine pictured on the “Models” page of Engineman website. To read the February 1950 issue of Popular Science  the article starts on page 206.

Six Candle power Stirling Engine

Thanks approtechie For posting this to YouTube this is a 6 candle Power Stirling Engine. As in an earlier post I explained that a Stirling Engine takes a heat source and a cold source and converts that into mechanical energy. Ideally you would want to use hydrogen or helium as the gas that fills the engine, because of their ability to absorb and conduct heat but most Stirling engines use the air we breath as the gas medium. The air is heated and it expands then a displacement piston moves the hot air to the cold surface and it contracts causing a vacuum. This moves the displacement piston the other direction and the process starts all over again.

Here is a PDF on Air Engine’s , Plans for small Stirling Engine.
