      Tesla’s macrofluidic valve — often just called the Tesla valve — is a sort of odd-shaped conduit for fluids in which a main channel is interspersed with a series of diverting teardrop-shaped loops. The loops are oriented in such a way that fluids easily flow through in one direction, but when reversed, the flow is almost totally blocked.

      In other words, it can be thought of as a sort of one-way or check valve, which anyone who has done a fair amount of plumbing or work with pumps will be familiar with. The advantage of Tesla’s design is it has no moving parts that can wear out like the springs and other mechanisms on conventional check valves.

      “While Tesla is known as a wizard of electric currents and electrical circuits, his lesser-known work to control flows or fluid currents was truly ahead of its time,” explained Leif Ristroph, an associate professor at New York University’s Courant Institute of Mathematical Sciences, in a statement. By experimenting with replicas of the valve, which was patented in 1920, the researchers found that the flow-blocking capabilities of the valve “turn on” by creating turbulence and swirling vortices in the conduit at a certain rate of flow.

      “Moreover, the turbulence appears at far lower flow rates than have ever previously been observed for pipes of more standard shapes — up to 20 times lower speed than conventional turbulence in a cylindrical pipe or tube,” Ristoph adds. “This shows the power it has to control flows, which could be used in many applications.” Even more interesting, the valve actually works better with a flow that is not steady but instead comes in pulses or oscillations. This could make it ideal for use in high-vibration environments

      Nikola Tesla was one badass dude.
