Using CT scans and 3D modeling, researchers found the fish’s spiral digestive system is analogous to Nikola Tesla’s ingenious check valve design.
In 1920, Serbian-born inventor Nikola Tesla designed and patented what he called a “valvular conduit”: a pipe whose internal design ensures that fluid will flow in one preferred direction, with no need for moving parts, making it ideal for microfluidics applications, among other uses. According to a recent paper published in the Proceedings of the Royal Society B, the Tesla valve also provides a useful model for how food moves through the digestive system of many species of shark. Based on new CT scans of shark intestines, scientists have
