3D Images of Sharks’ Spiral Intestines Reveal They Work Like Nikola Tesla’s One-Way Valve

3D images of sharks’ spiral intestines reveal they work like Nikola Tesla’s one-way valve to allow fluid to flow in only one direction without backflow

  • Scientists created 3D images of shark intestines from 22 species
  • They discovered that the spiral organs slowed down the movement of food as it traveled through the intestine
  • It also pushes food down in a way that doesn’t allow it to come back up.
  • This is similar to Nikola Tesla’s one-way valve which only lets fluid move in one direction, with no backflow or assistance from moving parts.










How sharks eat is a mystery in the scientific community, but a new study reveals that the guts of apex predators work just like famous inventor Nikola Tesla’s one-way valve.

By creating 3D images of the intestines of 22 species of sharks, such as spiny and smooth dogfish, a team of scientists led by California State University discovered that the spiral-shaped organs slow the movement of food and direct it to down through the intestine – a whole process that relies solely on gravity.

This is similar to Tesla’s innovation that allows fluid to flow in one direction, without backflow or assistance from moving parts.

The results also reveal that a shark’s intestines allow the giant fish to store food longer, which is why it can go days without eating.

For centuries, scientists have only had sketches of sharks’ digestive systems to help them piece together how the organs work.

But the latest study, published in Proceedings of the Royal Society, has incorporated modern technology to finally unravel the mystery.

The team used a computerized tomography (CT) scanner to create 3D images of shark intestines from preserved specimens.

This method allowed scientists to collect information without having to dissect the sharks.

Adam Summers, a professor based at the University of Washington Friday Harbor Labs and co-author of the study, said in a statement: “CT scanning is one of the only ways to understand the shape of shark intestines in three dimensions. .

“The intestines are so complex – with so many overlapping layers, that dissection destroys the context and connectivity of the tissue.

“It would be like trying to figure out what was reported in a newspaper by scissoring a rolled-up copy. The story does not stand up.

The scientists plan to create models of several different shark intestines using a 3D printer, which will allow them to see how materials move through the organs in real time.

And it should work the same as Tesla’s one-way valve.

Tesla patented his one-way valve in 1920, which is similar to traditional valves but with no moving parts.

It has a design that allows fluid to flow unhindered in one direction, but in the other direction fluid is blocked.

Tesla gave the following explanation in his patent: “The interior of the conduit is provided with enlargements, recesses, projections, baffles or cups which, while offering practically no resistance to the passage of fluid in one direction, other than surface friction, constitute an almost impassable barrier to its flow in the opposite direction [direction].’
