Using TNT as an energy source is a safety feature? Why not use nitroglycerin... At least it liquifies at a lower temperature, and it is not explosive in solid form. You would have to carefully limit the heat produced by the nanomachines, but it would certainly be self-limiting if things got out of control. It would also encourage nanotech developers to work on the smallest possible scale, especially when prototyping.

[Too unstable. TNT is actually relatively impervious to everyday insults -- it was invented to be shot from guns in shells, after all. I repeat: :^)
