"The capsule is strong enough to survive a storm at sea or getting crushed between two icebergs."

The first part is probably true. The second part is folly. "Remember the Titanic".

Agreed. There are mountains that don't survive getting crushed between two icebergs. If the sphere were made of solid tungsten, then okay, I'd buy it. Short of that, I have doubts.

The Titanic wasn't crushed, it was sliced, wasn't it?

The titanic was advertised as unsinkable and we know its history.

Advertising this capsule as uncrushable is a commensurate gamble.

Just make it out of carbon fiber. That's what they did with that uncrushable submersible that went to the Titanic.

I'm pretty sure the issue was with 'move fast and break things' and not using carbon fiber.

I think it was on the youtubes I was watching a story about how they built that thing and it was <spoiler alert> not really fit for purpose. I mean, no big surprise in hindsight.

		Carbon fibre has poor compressive strength and good tensile strength. That makes it inherently bad at holding pressure from outside in a submarine and good at holding pressure inside a spaceship or airplane.

Correct. The forces involved when icebergs move are vast. This thing will be crushed like a coke can. Even a deep-sea titanium sphere might not survive such an asymetric load as being crushed between a berg and a rock.
