Ever heard of submarines taking flight? Never? That’s OK because the Chinese are working on a submarine that is capable of flying underwater. Such a machine could travel from Shanghai to San Francisco in just 100 minutes, making it the fastest submarine known to man.
The submarine is being worked on by researchers at the Harbin Institute of Technology, which resides in the northeast section of China. The technology being used here is not new; it has been around since the Cold War, and the Russians have used it to develop torpedoes that are capable of traveling up to 230 miles per hours.
The technology in question would create an air bubble around a container that is lacking in friction. This would allow the container to travel at incredible speeds, which is almost like flying underwater.
