Okay, here's the setup.

A methane/natural gas powered 2 cycle piston on one side, driving

pre-compressed air on the other side gets safe Pulse Tube Liquefaction of

air below it's  -320 F boiling point  which is used  to cool natural gas off  the line to

the gas dryer in the laundry room to less than it's - 256 F boiling point.

 

Modified chain saw or Model airplane cylinder?

 

Atlanta noise ordinance compliant at ~ 90 dB, ~ 1400 Hz?   :-)
