Lightweight scuba tanks

[rexman24]

Has anyone ever heard or seen any attempt to build a lightweight scuba tank?
It could be made from titanium, unobtainium, other exotic metals, carbon fiber or nano fibers.
I realize it would be cost crazy.
I also think someone will say "what a dumb question". However they build Indy cars out of these materials, they weigh in the area of only 1300 lbs, yet are capable of keeping drivers alive, after hitting concrete walls at 240 mph, 99.999% of the time. Tyia.

They float too much

The Russians made titanium scuba tanks that can be filled to over 10,000 PSI in the 90's but never went anywhere. They showed their tanks during DEMA one time but never heard from them again.

If I remember correctly, the exploration of Wakulla springs was done partly with carbon fiber tanks. Divers found them to be too buoyant and I thought I read something about the helium in the mix was able to leak out and compromise the mix. I don't remember where I read that for a reference so maybe it was a dream.

If I can find a reference I'll post it.

How about someone invent some compensatory light lead
Yeah, that got heavy on water contact, or buoyancy vessels
I think we've already got something like that in a submarine

What would be the point, you'd just need to carry more lead to get neutral? Aluminum tanks are sometimes preferred over steel because they're cheaper to buy and maintain, not because they're ligher(with the exception of stage tanks). OTOH, carbon fiber tanks makes sense for SCBA, where reducing the weight the users have to carry is beneficial.

And add lead

Or use steel instead of Aluminium cylinders.

Something like this?

Whats SCBA? Where you breath via a hose to the boat?

SCBA is the breathing system that use fire fighters.
