I'm not sure that a Tesla Valve would be all that useful for tapping wave motion now that I think of it. It might not work. One way to think of it is to imagine using a one way ball valve. That has helped me in the past from ascribing too much magic or revolutionary nature to the Tesla Valve.
My current jet engine work does not include a Tesla Valve, though much of it is inspired by it. When I began, I imagined using a pulse jet, and attaching an axialy rotated tesla valve to the front of it, in order to replace the reed valves. I eventually moved away from pulsed combustion though. Too noisy and not the pressure levels I wanted.
2. Liquids and gases have different viscosity, so the Tesla Valve would be different for each fluid and flow regime. I am unfamiliar with this series-of-petals geometry you are remembering. However, it reminds me of this excellent work done on optimizing topology for different Reynolds numbers in Tesla Valves: http://www.senlin41.org/topology-optimization-of-tesla-type-...
3. One of the original intents of the valve was for Tesla's Bladeless Disc Turbine. In Tesla's time, materials were not what they are now, and thus valves with moving parts were not as reliable. Also, getting a valve that can close and open with high frequency is not always easy. The valvular conduit that Tesla designed was his solution to this problem.
Thanks for the book reference. I read "Wizard: The Life and Times of Nikola Tesla" But I hadn't seen this other book. I might pick it up.
You could make an array of them perpendicular to a plane. Perhaps, by etching them into silicon. On a macro scale, you could machine them with a CNC machine, or even with hand tools depending on your tolerances.
For sound, you energy density is rather low, so the material you wish to propel would have to be incredibly light. And you would probably have better luck trying to lift a plate of some super light material. The Tesla Valve is most useful as a device where you want to check the flow from moving one way.
Anywhere, where having a moving part is a pain in the butt, and you want a more robust system. When you're etching things into silicon, generally, you want to avoid have to make lots of tiny micromechanisms.
As a paddlewheel, it would probably not make sense to use the Tesla Valve. Turbines are well understood. If you want to make rotary motion, that's the way to go.

If anyone is interested, there are some very cool no-moving-parts jets that aren't as well known as ramjets: The lockwood hiller pulsejet is a pulsejet that doesn't need reed valves. http://aardvark.co.nz/pjet/valveless.htm
The Gluhareff Pressure jet is also a neat example. https://en.wikipedia.org/wiki/Gluhareff_Pressure_Jet
