Paranormal Electricity

So I was watching Everything Wrong with Paranormal Activity and I thought, “wait a second. Those ghosts can reliably slide kids across the floor? Not to mention all the door-slamming and chair-stacking and house-imploding they do. Where does the energy come from to do it?”

And then I thought, “who cares where the energy comes from? If I attach flywheels to all of my doors and chairs and children and whatnot, I’ve got me some free GHOST ENERGY!”

And not only that, but assuming my ghosts are malevolent and of less than infinite power, I’m making the world safer by exhausting them. It’s win-win!

Except now I have the incentive to murder people horribly so I can make more ghosts to supply me with energy I can sell. So I’m the bad guy in this story? Again?

Oh well, at least I don’t have to pay my electricity bill. Now who wants to come to my medieval implements of torture party on the equinox at the desecrated graveyard? There’ll be free Cool-Aid and witches!
