Well, for starters, you can build a device containing a pressure generator such as PUMP to create a wave of pressure that can shatter various materials, and if you add a heat generator such as URAN or PLSM with ambient heat on, you can make it so that the pressure wave is also extremely hot, melting/vaporizing what it can't shatter with the pressure.
If the KEP is supposed to simulate entropy on matter, wouldn't it also do the same to whatever device was producing the KEP?
