egoism, then again i was a kid
also drones, i thought i was a genius for coming up with the idea of remotely controlled optionally weaponized vehicles with cameras, then again i was a kid
I had the idea for a printer/scanner/copier/fax. Copier = scanner + printer. Fax = scanner + modem.
As a PhD student, this is my day-to-day 🥲
When I was a kid I learned how aircraft wings worked, then visualized one spinning so the airfoil was annular. Then I rememebered the frisbee already existed.
I was going through a lot of batteries at that time (hello, Radio Shack free battery punchcard!) and dreamed of wirelessly powering devices from a wallsocket transmitter. My TX looked like an upright toilet paper roll for some reason. A few decades later I was delighted to learn Tesla had been interested in the idea, too. Vindication, bishes!
This is stupid, but I thought I’d invented a shape of cup bottom that wouldn’t accumulate water in the dishwasher, but that was still stable while standing upright. Found an existing patent for my exact design after working on it for months.
