Reminds me of those Big Daddy suits from BioShock.

I believe this was one of the inspirations for their design!

I hesitate getting in a French car, let alone this death trap.

historically they have 3 giants: Renault, Citroën and Peugeot !

with globalization they’re everywhere now

Why would you hesitate to get in a French car?

Mostly a joke, but you should watch the Grand Tour: Carnage A Trois

The French have a questionable and hilarious automobile engineering history.

I wonder how the got the seals tight. So many joints with some old technology. When they have atmospheric pressure, they can’t work with overpressure keeping the water out, as the ocean will be the overpressure trying to push the water in. 🤔

Wouldn’t trust this thing my life. :)

One of the key reasons this one never took off - they could never get it completely waterproof. Such is the fate of early prototypes!

What was the idea of making it out of metal? Edit: I mean why cover whole body instead of just the head

What was the idea of making it out of metal?

What material options do you think they had at the time?

Ever tried to breath when you head is in atmospheric while your chest isn’t? For example in a pool: swim straight upside in the water, only the head is above. Your chest will be approximately 0.5m below the surface, probably more or less. So you have a pressure difference of just 0.05 bar between the intake (mouth) and the location of the target reservoir (lung). It’s a very noticeable effort you have to overcome with your breathing muscles.

And now imagine being just 20m deep with atmospheric pressure at your head. That would be a pressure difference of 2 bar. You probably won’t be able to inhale anything.

When scuba diving, the air you are inhaling has always the same pressure as your surroundings. When you dive at 40m you are inhaling air with a pressure of 5 bar (that’s also the reason why your tank is emptying much faster at that depth).

Keeping atmospheric pressure stable. When you go sufficiently deep into the ocean, the change in pressure messes with the human body - the Bends, bubbles in your blood; that kind of thing. This was an early (albeit unsuccessful - right idea, but the technology just wasn’t there to make the suit wholly sealed but still mobile) attempt to protect against that.
