The original idea, could be intesting in this way:- The hyothetical Higgs field, or Higgs particle gives particles mass; (px,py,pz,pt) becomes non-zero for some particles. Secondly, the electroweak force is resultant from spontaneous breaking--another (3,1) repartitioning. What field might send an O(4) space to O(3,1)?

Thermal energy is lost in compression, and later, decompression, upon use. I wonder what the efficiency figures are on this... The fluid heats upon compressing into the tank. After a time it reaches thermal equalibribum with ambient, say. As this happens the pressure drops a bit.
