Many thanks to Peter for pointing out a solution to the age old question of what happens when you attach a piece of upright buttered toast (which always falls buttered side down) to a falling cat (who always lands feet first):
Murphy’s law application for antigravitatory cats - Uncyclopedia, the content-free encyclopedia
Still, I can’t see how one could extract useful energy from the cat-toast phenomenon if it must be in free-fall the whole time.
A more likely perpetual motion machine is to rig a holy cross to a rigid harness, some fixed distance from a known vampire, such that vampire is repelled but can’t get away, and thus the whole apparatus begins to spin, powering a turbine. Viola! Electricity.
I wonder….Is the rotational energy released inversely proportional to the square of the distance between them? Who can say? The physics of vampires is still relatively understudied. How close the cross can safely come to said vampire (and therefore this what is the maximum power output of this contraption) is left for future work.
