A device that lets you breathe underwater without the tanks?

Recent CNN article on this subject.

Recent but from the same source and the same article:

I'm not into the technical stuff (batteries, etc.) as much as some on this thread but I'm more curious as to the use. The inventor sent me an email stating that the air separated contains 34% oxygen. Imagine that, no need to pay extra for nitrox anymore but you can't use these beyond 102 fsw though. Not too bad.

Wouldn't the generated air need to also be pressurized enough to make it into your lungs at depth (imagine snorkel with a tube getting longer and longer; pretty soon you can't suck in the air)?

The biggest problem I see is that there is not an efficient enough energy source available yet to make it practical. You would think that he would have more than a lab prototype by now if it was.

This guy here is also accepting investors in his new underwater breathing apparatus:

Why don't you email him at bodner@likeafish.biz. I'm sure he'll send you a prospectus and proposal too.

That guy wasn't dreaming?!?!?!

Stay down for several hours? Hmmm sounds like a very liberal multi-level profile!

ah... hello??

there are two major problems with this system:

first, the diver has no exposure protection. this means he will only be able to
work in warm water, and then, only for a short period of time.

this is easy to fix: he can just buy a coat and nice wool pants, and he'll be ok

second is the small hose size. unless he wants to go
deeper than your average swimming pool, he needs a longer hose.

this is also easy to fix: buy more hose at Home Depot, and string it together.

the ditchable weights also need work (like.. how's he gonna work underwater
with no free hands?). this is a minor problem, easily solved by wearing the
concrete blocks as ankle weights (this will have the added advantage of keeping
him in a vertical position, thus preventing helmet flooding)

:lol3: sorry can't help it

H2Andy,

I can't believe you missed an one important problem. His air supplier is using a bicycle pump. A foot pump is much more efficient. That way, additional fuel for the pump (a big mac, fries and a coke) can be ingested WITHOUT interrupting the air flow ...

Sheesh ... get with it.

I just don't understand why he needs the fins.
Does anyone think he's actually going to swim?

Perhaps they could have mentioned "oxygen tanks" a few hundred more times.
