What idea did Tesla sell? I'm aware of him working as a scientist for most of his life, but not selling an idea according to the criteria stated above.

- tyohn 19y agoI believe that Tesla sold several of his patents.
- thwarted 19y agoDoesn't a (non-software) patent require something resembling a semi-working prototype (at least back when Tesla was getting patents)? I say "semi-working" because there are a lot of patents for things like free-energy devices that never worked, but were built.
