The US Navy recently completed tank tests of a new deep-diving suit called the Deep Sea Expeditionary with No Decompression (DSEND) system that is light and flexible, yet maintains sea-level internal pressure around the wearer even when hundreds of fee… Continue reading Game-changing DSEND suit protects deep sea divers from pressure dangers
Propellers are designed to take a fluid, generally air or water, and use a rotating motion to push that fluid through. They’re evolutions, in a sense, from the Archimedes’ screw, which was likely used in ancient Egypt thousands of years before it was d… Continue reading Toroidal propellers: A noise-killing game changer in air and water
