Maybe it's a variation of a https://en.wikipedia.org/wiki/Pump-jet https://en.wikipedia.org/wiki/Pump-jet somehow using lasers instead of impellers to heat the inflow all internally and dampened/mostly silenced to the outside? Also enabling https://en.wikipedia.org/wiki/Supercavitation https://en.wikipedia.org/wiki/Supercavitation by emitting some of the 'exhaust' from the tip of the bow?
- Eddy_Viscosity2 3y agoIt says its using lasers to vaporize seawater all around the submarine which would create a submarine sized super cavity which would have very very low resistance. The problem is what happens when the bubbles collapse. That's what causes the cavitation noise, its when the bubbles collapse. They can do so with such force that they can pull metal out of nearby surfaces.

- Eddy_Viscosity2 3y agoIt felt like I was reading from 'three body problem'. I wonder if the author was inspired by the sci fi there.
