Own the Tesla Valve, as per the original design of Nikola Tesla, patented in 1920. See the video below to observe the valvular conduit in action.

Nikola Tesla invented this valvular conduit as a valve for his engines. Materials at the time were pretty bad, and valves were unreliable. Tesla figured that by removing any moving parts from a valving mechanism, he could create a simpler and more robust valve. The hook regions in the Tesla Valve reroute the fluid back in on itself creating a bit of resistance. All the hooks added together do a good job of arresting the fluid, especially when the gas or liquid is pulsed through the valvular conduit.

When you hold the valve in your hands after opening your shapeways package you are possessed of a strange kinship with the historical figure of Nikola Tesla. Pressing your lips to the valve, and blowing through it, you see that it actually works. In the resistive direction your breath is nullified to a mere whisper by the Tesla Valve. And in the non-resistive direction, air flows through unimpeded. It is startling the effect, and to think something so interesting as this valvular conduit was made so long ago.

I made this valve to commemorate Tesla's birthday on the 10th of July, 1856. Owning this valve is a way of recognizing a forgotten genius of unparralled creativity.

I'd love to know what this does to sound. But not enough, I regret, to spend $36.79.

I'm very curious, have you tried this valve in an actual application. Using your model and either stainless steel or ABS with screws as shown, or double bolted threaded rod to hold it together, what kind of pressure do you think it could withstand. What kind of efficiency numbers did Tesla claim when he invented it? Any references you might be able to supply would be greatly appreciated. I'm a big fan of Tesla and I've been working with some prototyping of his old patents. I hadn't seen this one, but I might have an application for it. Great job!
