A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

The article goes on to say:
TLDR: an advanced/modern diesel submarine is louder than a nuclear submarine in normal operation. Chugachugachugachuga. Then it goes into battery mode. It goes near silent, quieter than many nuclear submarines which still have turbines, pumps, etc. The diesel sub dissapears like a ghost. Torpedo away, too late.
And that's a relatively old sub. The French sub I mentioned is something like a decade newer, with newer and better batteries.
