Maxwell Demon Myth: $80 Compressed Air Powers Any Workshop During Blackouts

A $30 vane pneumatic motor on a 30 gallon shop tank at 150 PSI converts 117 kilojoules into 80 seconds of continuous high torque shaft work per discharge, per UC Berkeley EHS pressure vessel math. No inverter, no generator fumes. The same physics ran a Paris wide motive power utility from 1879 to 1994. Viktor Popp's Compagnie Parisienne de l'Air Comprimé hit 18,000 kilowatts by 1891 and powered Eiffel Tower elevators, dental drills, and Paris pneumatic clocks for 106 continuous years. The contrarian reveal is the Maxwell Demon Myth. Wikipedia, Harvard physics, and the 2008 Eiamsa ard review in Renewable and Sustainable Energy Reviews all explicitly call the Maxwell demon explanation of vortex tube cooling a documented misconception. Real mechanism: angular momentum transfer plus adiabatic expansion. The First Law rules out the self sustaining closed loop pitch.

A 30 gallon tank at 150 PSI holds 117 kJ. A vane pneumatic motor converts ~35 percent of that to shaft work, ~40 kJ usable. The vortex tube splits a compressed air stream into hot and cold ends via angular momentum transfer, not Maxwell's demon. The First Law caps every closed loop attempt at lossy efficiency under 20 percent, so no self sustaining workshop power plant has ever worked or ever will.
