This group ( The HAES ) will converse on topics related directly to Hot Air Engines. Anyone conversing must obey two laws: The First Law and the Second Law of Thermodynamics. Anyone knowingly or unknowingly breaking these laws will be informed of their misdeed and asked to reform by learning about these laws or leaving the group.
Solar energy sources for Hot Air Engines will also be discussed; how they work and how to build such solar energy collection devices. This site is open to the public and anyone may post things of direct interest to the group.
The idea is to promote the design of practical robust Hot Air Engines, not necessarily of the Stirling cycle, with a low technology flavor, but which use some high technology materials amd constructional methods coupled with sound engineering principles and ideas. A further goal is to create a hot air engine weighing less than 50 pounds and producing 1/2 to 1 brake horsepower excluding helium or hydrogen filled engines.
