Buoyancy device and wheel and bubbles

Care to elaborate? 

Yes if you would like...

I made a very stupid mistake when I replied to the post. so I edited it and due to my embarrassment had nothing more to say..

But I guess I'll post it anyway...

mindsweeper; It looks like some form of surface aerator. But he is going to have to get the bubbles a lot lower.

Hi grayone

I was thinking along the lines of the flow of water round the lower ring, as with the 1st picture in the tank the water would have trouble flowing in one direction when in a large square tank.

  grayone & mindsweeper,
What is pumping the air into the water ? A turbo charger or blower could not do it. A blower requires a massive amount of energy to rotate. Something like Newtons' v*m = p.
How much velocity does a blower need before it starts pumping air ? On an engine, it creates drag until sufficient rpm is developed to increase air flow sufficiently to allow the engine to generate enough power to compensate for the 2 heavy weights a blower uses.
After this, then the efficiency that the gear can convert the lift of air in the water into force comes into question.

Hey Jim..

Yes, using heavy pumps like a turbo or blower would not work in this case, perhaps a small generator for driving a pump would work. None the less I think the overwhelming problem would be water pressure where the pipe enters the bottom ring. TBH I wasn't sure and was only a thought I had and while it was still clear in my head I made the drawing, posted and then realized my mistakes and removed it.. But as someone asked "could I elaborate on my edit:" I posted it again.

That's also how they came about calling oxygen in the blood, the bends. Sorry about the history lesson 

by oxygen in blood, you really mean => nitrogen (bubbles) in blood. As air is mostly nitrogen.

high pressure oxygen => hyperbaric oxygen, is somewhat good for humans, if you don't overdo it.

But then, considering quick depressurization allows oxygen levels to return to normal, why doesn't nitrogen do the same ? Is it stored in tissue ?

Nitrogen is distributively forced into the blood and "disappears", but as the
external high pressure on the organism is reduced it comes out in the form
of bubbles that are not going anywhere. This is alternately known as
"Nitrogen Narcosis". Oxygen is chemically captured by iron in the red blood
cells and works differently. Nitrogen is not a chemically reactive gas at normal
temperatures, so deep divers substitute in Helium, a noble gas for it, which
does what you want.

Sorry for the off topic post.
