Building a device that can reduce the energy of a perpetual motion machine gives me a head...

... I didn't even know you could create a true perpetual motion machine in the first place.

I'd think friction would be the primary draining force, though, and while this might be too simplistic a guess, if you're looking to draw energy out of the reaction, that might be the easiest way to get at it. A wheel with brakes attached, perhaps, dependent upon the machine's form...

I never really was a mechanist or physicist, though, so just a guess.
