#2It made sense to Tesla then.
It may be better "understood by general public today", but it sure as hell wasn't a random, pointless invention 100 years ago.

#3That's pretty cool that it doesn't require any moving parts and manages to reduces the flow to almost a trickle when the direction is reversed.

#4The paper itself is quite interesting. [1] They describe using 4 of these Tesla valves in a configuration similar to a bridge rectifier for liquids which would take oscillating flow input and produce a constant output.

#5Another cool (but useless?) invention is the Tesla turbine: https://www.youtube.com/watch?v=j7DNKIsdBZc

apparently they see some limited use in reverse, as pumps.

If I recall correctly, these are actually used today but with more viscous fluids like oil and in reverse as a pump.

#8If you want to get into the mind of Tesla a bit I highly recommend "My Inventions", his sort of autobiography where he described how his mind worked. He spent a lot of time developing his imagination at a young age and "traveling" in his head. I was surprised to read that he would visualize entire designs in his imagination and then go through prototypes and iterations several times before bringing that idea into the physical world.

My method is different. I do not rush into actual work. When I get an idea I start at once building it up in my imagination. I change the construction, make improvements and operate the device in my mind. It is absolutely immaterial to me whether I run my turbine in thought or test it in my shop. I even note if it is out of balance. There is no difference whatever, the results are the same. In this way I am able to rapidly develop and perfect a conception without touching anything. When I have gone so far as to embody in the invention every possible improvement I can think of and see no fault anywhere, I put into concrete form this final product of my brain.

If this weren't HN someone might attempt to draw a humorous connection between this passage and his reported lack of need of romantic relationships.
