New diving technology
News article
An Israeli Inventor has developed a breathing apparatus that will allow breathing underwater without the assistance of compressed air tanks. This new invention will use the relatively small amounts of air that already exist in water to supply oxygen to both scuba divers and submarines. The invention has already captured the interest of most major diving manufacturers as well as the Israeli Navy.

I am sure that they are looking for volunteers to sign up (and sign long releases with lots of very small print) even now.

If it requires no tank and pulls oxygen out of the sea would there still be a decompression stop at 15 feet? Also would he be able to go past 300 feet when oxygen be comes toxic?

O2 starts being toxic at 1.6 PPO2. That's about 20 fsw. Air has enough O2 to start posing a risk at 214 fsw. The old standard (pre 1980 something) was 2.0 PPO2 or approximately 290 fsw. Recreational divers do a "safety stop" - not necessarilly a "decompression stop". Pure O2 does not require decompression - your body metabolizes it. FWIW - Peregrino

Perigrino,
Great post!
Being a non-diver I understood exactly as much of this as something FS might write.
Carry on.

Bill - You ever get this way (or we meet someplace interesting) and we have the time to go diving - it's my treat. Til then - we won't worry about what you don't understand and I don't get paid enough to teach. My post was a gentle hint to S359 that he needs to study a bit more before asking questions. Peregrino

Hint taken.  It's just been a few years since the last time I dived. Forgotten a few things. Thanks for not rippin me a new one.
