what about the earthquake machine?
Tell the Truth
This, basically.
He had contributions (significant ones, even), but he went nuts in his later years, and even his early role has been exaggerated by internet schizos, people who demonize Edison for political reasons, and (in the past few years) Serbian nationalists.
The War of the Currents was well underway by the time Tesla showed up on the scene -- he improved the AC design that Westinghouse was already using. Yes, that's impressive by itself. No, he didn't make the first AC generator. No, he didn't make the first commercially significant AC generator. Almost every Tesla fanboy I run into seems to think the former, then tries to fall back to the latter.
The death ray "design" (which is probably what OP is referring to) was notebook scribbling. To this fucking day I see people try to pass it off as a "set of blueprints".
Tesla's autobiography reads like the fecal scribblings of a mental patient on the wall of his cell.
This happened.
This desu
This.
Between literal autism, completely unwarranted self-importance, and an unjustified persecution complex, he's essentially the patron saint of internet #IFUCKINGLOVESCIENCE brainlets. Not that Tesla wasn't smart himself but he's vastly overhyped by his followers.
Tesla's inventions utilizing radiant energy has huge implications economically. one of the biggest reasons why it has been supressed so much.
>We're any of them viable?
not really
Tesla was really more of a tinkerer than a scientist. He made a lot of pretty damn cool shit but a lot of it was pretty novelty-tier. It technically worked but wasn't nearly efficient to ever be used in industry.
tesla turbine works now that material and manufacturing science has advanced, and has found application
tesla valve seems to be an answer in search of a problem
these are really the only two things I have bothered to ever find out about
