Gravity powered water generator

Let's look at this one stage at a time.  Starting with the air pressure going to tank C the air pressure has to be high enough to overcome the pressure of the water at the bottom of tank C.  Now the air pressure going into tank B has to be high enough to overcome the pressure of the water at the bottom of tank B AND the pressure of the water at the bottom of tank C.  The original supply of pressurized air has to be high enough to over come the pressure of the water at the bottom of tank A AND the pressure of the water at the bottom of the other two tanks.  You will need some pretty high pressure air to overcome all that.  And that high pressure air will take some considerable power to be produced.  I hope this helps your understanding about air and water pressures.

Since webby brought it up, here is an article about buoyancy control jackets that divers use when diving.  You will probably want to skip down to the operation section instead of reading about all the different kinds of buoyancy devices.  As you read about the operation you will understand this is not as simple as you might have thought.  It does take some time and practice to get good at using a BC.  Most new divers don't get really adept at it until after making several dives at a lot of different depths.

Ok, I admit I am probably rubbing my own nose in it, but here is another thought for the air bucket tanks.
  Unless there are air systems that work like webby1's home made differential pump using air instead of water I don't know if  the enclosed tanks can justify all the pressure needed to be overcome.   Only a build or a lot of math could figure that out.  I looked on line and found nothing I could afford that would get me that kind of air supply.   citfta showed how I would need to overcome the equivalent of at least three tank depths combined  to reuse the air.  as she said,  That's a lot of pressure and expense. 

So, my next thought is to just reverse the original system  and use the rope pump to bring air down to the buckets for the lift. I can't see where there is much back pressure involved as the rope pump is dragging the air down through a pipe and allowing it to escape through the exhaust port at the bottom.   The rope pump is driven by the buckets.  Initial start up is by crank handle or motor or my original water generator buckets.   Forget the enclosed system. 

Is there any difference?  You can add more buckets if you want for more lift.  I no longer need a compressor.

I am not losing energy lifting weight as in the original design.  But there are losses to compensate for. 

Though personally,  I still think my original idea is better.  (Just can't throw my baby out with the bath water).   

Webby1;  I to get a timed out message.  And no redo on the message.

Hi Brutus:
   For what its worth, you still dared to walk down that path that they say cant be walked down. You dare to question and that is how answers are found. I just finished a design that I was so sure that would work. It didn't but I did get to see where my quest went wrong. It may never go but it did spawn a new avenue that may well have the answer.
   Keep to your decided path as many will tell you, "you are just wasting time and money". Well hey it is yours and your decision. Then there is the thrill of the chase which you can not afix a value.

Brutus,

I like your last idea.  I can't think of any reason why it might not work.  I would do away with the tube and flaps idea and just use the buckets and chain to drive an air compressor with the outlet at the bottom.  It will take some real power to turn the compressor fast enough to pump enough air to keep the buckets moving.  But the proper ratio of gears or pulleys might solve that problem.  It would be interesting to see how close it could come to being self powering.  Do you plan to build it?

Good Luck,
