Aw man, I`ve been designing this in my head for TOO long.... Shame it`s already been made.

If it was like a jet (beacause of the masive amount of water that was needed) wouldn`t you be able to use that energy to make new power to the batteries maybe?"

I think if you could use the power of the machine to recharge its battery....that`d be akin to having free energy, which is impossible, I believe.

I bet they make one like a snorkel mouth peice and like a tube of side ways toilet paper on its side that would be cool

I still don`t think it`ll be as cute as Harry Potter whit gills *sigh* ... (well yeah I know.., you don`t have to say anything)

FINALLY, i`ve been waiting for this since I was three, now I can REALLY be like a mermaid (with a big, obnoxious, most likely loud machine strapped to her back), but a mermaid, nonetheless...

Interesting idea, but they already have what they call "re-breathers," which, I guess strip off the Carbon from the CO2 we exhale and provide the cleaned O2 back to the user? I don`t know exactly how they work, but here`s a site if you`re interested: http://www.rebreather.com/

And, since a rebreather uses your own recycled oxygen, the fishies don`t die! :-)

YESYESYES.

See, the thing is, that even with the overuse of aoxygen and all that, this is not the final product. It`s like... It`s like think back to the first airplane. Once the initial breakthrough was made, it just got better from there. :D

...I cannot think of a better example than that. D: The point that I am trying (horribly) to make is that it`ll get better and more convenient. And probably safer. So yeah. Hurrah for fish-ness.

She is right,you know.We shouldn`t mindlessly kill fish to do something that we can already do,safer.Sooo....

rinjihalfelf, who in the hell scuba dives in a lake? and i dont think that we will use up all of the oxygen in a lake anyway, because when you jump in, it mixes more oxygen in. soooo...no.

Um, wouldn`t this harm the environment of a small ecosystem like a lake is used too frequently?

First off, fish are cold blooded.... they don`t need as much oxygen as warm blooded animals and can live in the lake without messing up the oxygen content.

If we had too many people scuba driving with the invention in an area... we`d probably see alot of dead suffocated fish.

Just a thought... Maybe we should work on making people cold blooded for the sake of the fish. lol.

Also, won`t they have some sort of risk in really cold water? You could get hypothermia fromt eh inside out...Ouch!

I supposed you could just run an extension cord up to a boat for power.

One day the Super Battery will be invented. And that my freinds will be a wonderful day indeed..................In the mean time if this thing can be powered by wave action I`m moving underwater. Surface dwellers farewell.

Pretty awesome. I wonder if the batteries will be able to last long enough for 3 or more hour trips underwater

Wow. This invention is long over-due. Why didn`t someone think of it before! Once the kinks are worked out of the system, this guy will become a billionaire overnight.

"Since every litre of water contains about 1.5% of dissolved air, Bodner`s system must circulate around 200 litres of water per minute to accommodate the breathing needs of an average person."

...that`s 3 1/3rd liter a SECOND! That would be somewhat like having a jetski on your back...

Lot of hating on the invention in the article though. I thought it was pretty amazing. It is still a very new technology, maybe they can work out the kinks . . .

When it`s fully functional I can go skinny-dipping on even more of a regular basis.
