Tesla fluidics

Can’t find a specifically relevant ‘Topic’ so this will have to be another ‘TeaRoom’ job: **LINK**

An interesting aspect of physics but unless I have missed something, I can't help thinking that we already have very effective fluid "diodes" in both biology and artificlal systems: non-return valves!

There was a brief foray into pneumatic 'fluidic' systems in the '70's but the increased reliability and power handling of semiconductors soon buried any further use of such devices.

I suppose what you missed is that Tesla’s version has no moving parts [except for the fluid itself]

I remember working on pneumatic 3 term (PID) controllers in a glass factory in the early 1970's. They were used on electrically heated furnaces (and others) as they were more immune to the electrical noise such furnaces and their downstream conveyors produced.

But leaks were a constant problem!!

And in the early 'seventies I worked a circular division tester that that had little plastic units providing the basic logic functions, powered by compressed air.

How big would a CPU be if built from such logic? And syncronising the events would have lead to a slow device.

This thread raised very little interest, but I will just add this from today’s News:

Aha! Prior art!

This is all way beyond me, but isn't it like eddy currents in a river causing the margins of the river to flow in the opposite direction ?
