<t>I partially agree with what you posted. Introducing heat where the cycle starts instead of at the middle of the end of the power cycle could put power to the cycle sooner making the engine produce more power. Using helium instead of air can help allot too since it expands allot more that air does...

<t>The scroll motor only has one moving part and it can be a closed loop system <br/> just like a Stirling engine. One difference being it doesn't have a defined <br/> hot and cold side unless you would consider the in side the hot side the out <br/> side the cold side. It's closer to one of the sin...

Has any one ever made a Stirling engine from a scroll expander. It's
basically a scroll compressor that is run backwards. It only has one
moving part.
Second question is would this type of solar motor be as efficient as
other Stirling engines?
