FROM SHANGHAI TO SAN FRANCISCO IN LESS THAN TWO HOURS WITH THE SUBMARINE CHINESE

From Shanghai, in less than two hours, you can reach San Francisco aboard a submarine crossing of the Pacific Ocean made​​.

A revolutionary work on this project is China, which is working on the super submarine equipped with a special liquid membrane, which constantly bathes. The medium enters the water, and when it reaches the speed of 75 kilometers per hour, the membrane comes into operation. This avoids an initial impact with the sea is not tolerable to humans, and by managing millimetric liquid flow membrane also allows the submarine ride more smoothly.

In theory, according to calculations made ​​in 2001 by the California Institute of Technology, half driven by technology supercavitation – a bubble of air around the middle, to help him overcome the problems caused by the friction with water – can reach speeds sound, or about 5,800 miles per hour. At this rate, it could cross the Atlantic in less than an hour, and the Pacific in less than two hours.

The technical problem is the construction of a motor large enough and powerful to reach this speed and maintain it for all the time necessary to reach the goal.

In fact, the Soviet torpedo Shakyal, the medium submarine fastest ever developed (came to 370 km / h), had a range of a few miles, because it was thought only to be fired in a straight line against a target relatively close.
