If I remember right, the operating temperature for DNA is around 75 deg. C and isolated human cells produce temperatures as high as 5000 degrees.
I don't have a clue if SHC is possible, but sufficient heat is there to dry out the body and vaporize volatile organic materials should they exist. The 5k temp is enough to ignite most volatile substances. http://physics.stackexchange.com/questions/59316/human-as-a-heat-engine
"Volatile substances" when every cell in the human body is mostly water???? Your numbers are COMPLETELY wrong - this is as much a crank post as all the rest you've made here.
