The man was a true visionary.
30 years ago, I had an interim job as the maintenance guy for a sheet metal/machine shop. I had to pull a huge motor off an ancient press brake one day. On it’s spec plate, it listed Tesla’s patents!
In 7th grade Science class, I built a 250,000 volt Van de Graff generator. Got an A. But then I hooked it to the classroom’s doorknob, and sent a foot long bolt of lightning to anyone trying to get in! Got a week’s detention for that prank! The next year, I wanted to build a Tesla Coil. My Dad said, in retrospect, quite wisely, “No Tesla Coil!” I still wanna build one though! Built a Cloud Chamber instead for that year’s project.
