Chinese scientists are developing a laser engine for supersonic submarines

The next generation of Chinese nuclear submarines could be equipped with laser engines. In theory, this would allow submarines to move faster than the speed of sound in water and do so silently. To do this, thousands of optical emitters will be built into the body, and a 2-MW laser will be enough to create a thrust of 70 thousand N - like a jet engine […]
