If the vacuum affects the rotor, it seems to me that the rotor is also affecting the vacuum (its virtual particles). Someone ought to be able to make some hay out of that.

If a pair of virtual particles come into existence and the rotor whacks one of them and then gets out of the way before it can interact with the other one, can we get an effect like Hawking radiation?
