but couldn’t loosen it from the hose bib. It was seized! We tried 4 different options, each time escalating the leverage and force when one didn’t work. First things first: spray the heck out ...
Their prototypes kept fluids flowing in one preferred direction with no need for flaps to control that flow and performed significantly better than so-called "Tesla valves," particularly when made ...
Inspired by that study, postdoctoral researcher Ido Levin and colleagues at the University of Washington set out to replicate the spiral valve's one-way functionality in rigid 3D-printed pipes.
Now, one-way pipes have been attempted before. More than 100 years ago, Nikola Tesla patented the Tesla valve, a one-way fluid flow device with no moving parts. However, as the team tuned their ...
