Re: Which design is the most efficient Stirling Engine?

There is a difference between efficiency and power. The Alpha configuration apparently has a better power-to-weight ratio than the Beta, because the Alpha has two pistons. The gas inside the chamber provides better power if it has a lower specific heat capacity. Helium is good for that. (One must ad...

Best Role for Alpha, Beta and Gamma Stirling Engine Configurations?

There are 3 main configurations for Stirling Engines: Alpha, Beta and Gamma. To which sort of application is each configuration best suited? For example, might one of them be preferred at higher temperature ranges or might one be better suited to more rapid motion? Or perhaps is one an improvement o...

Video Resources of Stirling Engines

Does anybody have a link to some high quality GIFs or instructional videos on Stirling Engines?

Something that explains how they work and their possible uses, that sort of thing.

Which design is the most efficient Stirling Engine?

Of all the possible engine designs, which is the most efficient in converting the temperature differential into motion?

Bang per buck, which gas and metals result in the greatest power from the components?
