Breathing underwater
So I saw this today:

http://themindunleashed.org/2014/10/scie...tanks.html

It is basically like an oxygen battery - the "aquaman crystal" stores oxygen for later use. I'm not quite clear on how exactly we'd use it, just... suck on it? Eat it? According to the article it's very efficient and could be better than a scuba tank.

Somebody smarter than me please tell me I can be a mermaid. Heart

I really hate when articles on science/technology get basic facts wrong.
No one dives with oxygen tanks. We use compressed air or Heliox. Geez.

Anyways, while the material exists, there is not yet any delivery mechanism for oxygen to the diver.

It might take some time to work that out. Don't hold your breath. Drinking Beverage

Hopefully some engineer will figure out how to make a delivery system.

"Oxygen tanks" is a constant source of aggravation for me as well.

I sometimes dive with Enriched Air called Nitrox, all that is is a higher percentage of O2, say for instance a 32% mix = 32% O2 and 68% Nitrogen instead of the normal 21/79 ratio we all breathe.

Some technical divers will take a bottle of 100% O2 to speed up desaturation but it is only used during decompression stops since O2 is toxic at partial pressures greater than 1.6 and causes convulsions.

TriMix and Heliox are certainly used by tech divers since helium is an inert gas and doesn't build up in tissues like nitrogen.

Yeah, I forgot Nitrox. I've only ever used air - I'm just a casual sport diver.

You can take the class online with PADI, no water work required, deals only with theory and partial pressures of gas, you wouldn't have a problem with it. It really adds a margin of safety and additional bottom time on dives 100' or less, I highly recommend it, especially as we get older.
