Made mistake on CO2 -- less than air

Btu/lb/deg F

Air         =  .2562   (68 F to 1470F)

Alcohol
(C2H5OH)    =  .4534   (226-428)

Ammonia     =  .5202   (73-212)

Water vapor =  .5100   (356F)

Methane     =  .5929   (64-406)


Hmmm -- methane would make the best working "fluid"

Steam is the most available though!!

Still -- a 3 foot diameter piston to get "power"!!

Volume of 3 HP diesel = 385 CC per stroke!!

How many strokes to work a volume equivalent to one pound of methane??

Well -- let's not forget the delta-T factor.

That is how many degrees of change we can achieve!!

Say -- 100 degrees -- so now 59.29 btu per lbs

Further -- why not run this device under pressure - -and less compression
ration - -as in larger capacity flash tube boiler??

Steam -- well -- I can work it our for steam -- maybe later -- got to run
-- planting coconut seedlings today.

I have a feeling this might just work though!!
