Johnfaber is right, the more it compresses, the more power it releases with prot and neut, also, you can cool it down with elec, and its the basic of many bombs :D and engines :D And cookers :D
The description for DEUT includes "volume changes with temp"

Nope, no glitch. DEUT changes volume with temperature. You'd be surprised how much you can put in a single pixel.
