Addendum:

 

If there's a worry about O2 hazard, a Pressure Swing Absorption

Air (N2 Ar,O2) separator can be gotten by modifying an old

(up to 90% purity O2 at 10 liters/minute) Medical Oxygen generator

to run off a methane/natural gas powered engine.

A 20 lb capacity propane bottle stored inside the "home brew LN2 dewar can

hold about 18 liters (17 pounds) of LNG..

At ~ 21,000 BTU/lb LHV, 17 pounds of LNG is about the equivalent of

2.75 - 3.0 gallons of gasoline.

 

Feed the O2 gas into the 2 cycle engine?

 

SAFETY DISCLAIMER: Naturally.  :-)

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?   :-)
