The CR5 "is a chemical heat engine," says chemical physicist Ellen Stechel, program manager of Sandia's Sunshine to Petrol project that basically seeks to reverse fossil-fuel combustion. Answer (1 of 3): Yes, at least in principle it can be, since strong interactions and electromagnetic interactions, which are responsible for many nuclear fusion reactions, to a very good approximation conserve the discrete symmetries T,C,P separately. The decay is an extremely frequent satellite-process that accompanies the thermonuclear chains in stars. Save Comment.
