Alternative Energy production
Imagine a perpetual motion machine entirely operated by merchant bankers: a turbine wheel with spokes radiating out from a central point, the spokes at belly height. The bankers are placed behind the spokes, their (ample) bellies both powering the motion of the turbine and providing the chemical energy for the continuous movement. They are blinkered so cannot see behind them. Their motivation: each spoke has a vertical wire attached which wafts high denomination bank notes enticingly just in front of their blinkered face: they reach for the notes, and these are snatched away by the motion, thus they continue to turn the wheel.
It could be marketed as a free gym for those with the biggest credit crunch hangover. As their bellies decrease in girth, the amount of money increases - the motivation could thus be improved via an element of competition - they could boast to the others in their post-energy-generation "health club" about the size of the wad they are chasing.
