How do submarines work if you put some door for people to enter in, or how do submarines can fire torpedo without getting flooded? The answer is some engineers found a way to do it, there are videos and articles that will explain it if you are really curious and not trying to find the most stupid excuse possible (there are many electronics with replaceable batteries that work under water)

Aren’t you just making my point? If they have to get a reactor out of a nuclear submarine, they have to cut the whole thing open. Engine work is either done inside shell is cut open and they just reweld it back. It isn’t cheap at all.

This sounds like you are trying to make a Reddit comment rather than an HN one.

Nope. My point was that you can have things in hyper hard conditions, underwater at high pressure and salt and you can still say shoot torpedo.

Do I need to send you video proof that tooth brushes with replaceable batteries exists or you can google it yourself? My son has one that is almost 10 years old too , it uses 2 AA batteries , brand is Oral-B .
