Homemade Air Engines that Work, DVD and documentation,
including 11 x 17 foldouts of detailed drawings: (1) Torquerack One,
prototype for an air engine that puts out almost twice the torque it would
put out if it used a crankshaft, by replacing the crankshaft with gears;
(2) The Littlefoot Engine, a two-stage compressor converted into a
two-stage air engine.

An electric motor
is an inefficient machine while coming up to normal speed; a steam
engine is inefficient until the walls of the cylinders are thoroughly
heated; but a compressed air engine is most efficient,
thermodynamically, with the first movement of the piston, because the
walls of the cylinders are then at their highest temperature. This
fact would point to the use of compressed air locomotives wherever
stops and starts are to occur with great frequency.
U. S. Patent No.
868,560, Interheater for Compound Compressed-Air Engines, Patented
October 15, 1907, by Charles B. Hodges of Pittsburgh, Pennsyvania.
The French three-stage design beginning on the next page was based on
Hodges’ patent, but takes it a few steps further; heat was absorbed
before all three stages, and regenerative braking was incorporated to
add compressed air and heat to the tanks and interheater.

question the status quo on what compressed air really does, and what that
has to do with the equations, charts and assumptions used to define the
abilities and limitations of pneumatic power.

Maxwell’s Demon Gets a Job (3rd edition),
The answer to James
Clerk Maxwell’s famous riddle about self-fueling air engines and the 2nd
