In 1920, Nikola Tesla—the closest person in the world to God—invented a strange passive check valve that had no switches, no movable parts, but allowed fluids to flow first in one direction and then not well in another.
Does it feel incredible? It's not a sensational thing. In fact, tesla valves have long been thought of as a simple switchgear that allows current to pass through without making any noise. What's even more amazing is that the valve invented by Tesla has not been widely used, and it is difficult to point out its use even now. But a study by California State University, Dominguez Mountain, the University of Washington and the University of California, Irvine, shows that the Tesla valves we humans abandon have long been used by sharks in the ocean and have brought them huge benefits.
Tesla valve Tesla itself is a valve catheter, its interior consists of a series of AC pipe pipe branching, each branch has two branches, one of which is curved and the other branch is reversed, which will isolate the fluid from the arc branch from the fluid of the inclined pipe, resulting in a loss of energy.
When multiple such branches are connected together, the reverse entry of the liquid loses more and more energy and may eventually not flow, making it a special kind of check valve. But the liquid flowing in is unimpeded. This is why in some places there is "reverse current", also known as countercurrent extraction. For example, if you drink water with a Tesla valve straw and drink it casually, you will have a hard time drinking the opposite water.
To study how sharks digest food, and what food plays in marine ecosystems, the scientists used computed tomography scanners (CT) to create high-resolution 3D images of shark intestines, allowing them to study complex shark intestines without having to dissect it. This technique offers the possibility of further understanding the shark gut. Sharks are rich in protein, fat and carbohydrates, but their gastrointestinal tract is very narrow and there is almost no room for food. Therefore, it cannot be fed normally. Because the shark's intestines are so complex with many layers overlapping inside, if dissected, it can disrupt tissue structure and connectivity, just like cutting a rolled-up newspaper with scissors and trying to figure out what's inside.
The study found that the shark's intestines are spiral-shaped, like Tesla's Tesla method invented 100 years ago, slowing down the movement of food and guiding food downward through the intestine.
What does this mean? Most sharks take days or even weeks to eat a big meal, so they need to store food in their bodies and extract as much nutrients as possible, the researchers said. However, scientists have discovered a new way to inject water into sharks to help them store and extract food. Experimental results show that this method can keep the shark healthy from a few months ago to the present. The slowing of food movement caused by the Tesla valve intestine allows sharks to retain food for longer and use less energy to process food.
In other words, it is difficult to turn the food that sharks eat into rice dumplings, because the food that becomes liquid is slowly slowed down and moved in the stomach by one branch after another of the intestines. So after watching "Finding Nemo", we will have an urge to cry. If we turn food into rice, it must be delicious; but if the food becomes noodles, it is not right! If the food also has an idea, the heart is estimated to be a collapse, so many days, only to the eighth branch, must be pulled to digest, you are really happy!
Sharks do seem to be a microcosm of food conservation. And it's rich in recipes! This is no joke, though, they do have a "scientific" diet. Shark diets are actually very strict and delicate, and almost every step cannot be wrong. To reduce food waste, even the smartest people have evolved Tesla valve guts that they don't know how to handle. Perhaps it is precisely because of this particular intestinal structure, due to changes in the marine environment, that their populations have withstood top predators again and again and have been fortunate to survive.
If Tesla knew everything, he would definitely be knocking on the coffin board now, for God's sake! Why don't you guys sell it to us? We invented all of you, and who told us to invent so many technologies?" This is what a self-proclaimed "Tesla inventor" said. The old man invented the Tesla valve for 100 years, the patent has expired, you don't use it, let others use the shark first, human beings are ashamed!
Perhaps hearing the sound of Tesla's coffin, the researchers decided to go ahead and make Tesla intestinal models of various sharks, test how fluids pass through, and work with engineers to find inspiration for industrial applications, perhaps filtering wastewater treatment and microplastics in water, and cleaner nature.
What is a Tesla valve? What is a Tesla battery? What is a Tesla motor? These are the concepts we can most easily confuse in physics and mathematics. Let's introduce these three concepts to you! What is "Tesla"? Video 100100 years ago Tesla invented a valve, but this valve has never been used and may come in handy
