A Tesla coil. The poor guy deserves more love than he gets, he was one of the greatest scientists of his time and he got next to no credit for what he discovered. Plus then I'd have a generator for when the power goes off...that's what it does right?
WYR live next door to an old man who insists on mowing his lawn at 3:00 am every morning(happened to me) or live next door to a construction site that operates late at night?
