State reduction and energy extraction from black holes

Abstract
I show that attempts to detect Hawking quanta would reduce the quantum state to one containing ultra-energetic incoming particles; couplings of these to other systems would extract ultra-high energies from the gravitational collapse. As the collapse proceeds, these energies grow exponentially, rapidly become trans-Planckian, and quantum-gravitational effects must enter.
