This is just a idea I have had for awhile, It would be tough to seal.
Could this work?
Inroades,
Here is a link that was in the recent past to a water wheel that had similar principles. Read Reply #29 from Stefan. I think it would apply to your idea. It is very difficult to keep the water from leaking out. Then, once the water is gone, did you produce enough excess power to refill the tank?
Dream up a good sealing system and maybe it has a chance.

it need also POWER to "press" this devices against waterpressure inside the tank !
P
If the inlet seeling gate works then yes
However if there where inlet seeling gate's that worked like that all sorts of machies would be possible with simmerlar pricipals.
Sorry for butchering your nice picture.
But what about placing it all in water and using magnets through the glass with gravity to pull them back down.
It probably cancels itself out somewhere, but hey I felt like drawing LOL!!!

OMG I just had the same thought about this 10 minutes ago.
But, as someone just stated, keep the water from leaking without too much friction.......
How about this idea, remember the old bird that sips the water, stands back up, then back down? forever? I think homer Simpson almost destroyed the nuke plant with one.
Why can't that tech. be reinvented on a larger scale? Anyone?....
do a search for drinking bird here at overunity.com :)

maybe.. but wouldn't have enought power...
Here is a good link that describes several flotation based motors and why they won't work...

GREAT CONCEPT...HOW ABOUT PUTTING THE WHOLE THING UNDER WATER AND PUMP AIR INTO THE CYLINDERS/ BALLOONS AT BOTTOM AND FLOODING THEM/ DEFLATING THEM AT THE TOP ON WAY DOWN.THE BELT COULD INCORPORATE A TRANSFER MECHANISM FOR THE AIR ,THE WHEELS AT TOP AND BOTTOM COULD CONTROL VALVE ACTIVATION.......OR PRESSURE VALVES COULD BE USED .......IT WOULD BE LIKE A STRING OF SUBMARINES BLOWING BALLAST ON ONE SIDE AND SINKING ON THE OTHER........IN THIS WAY YOU DONT HAVE A PROBLEM WITH A WATER SEAL MECHANISM.........
The reason that this device will not work is that flotation requires displacement. When you force the float into the water it displaces water upward. When the float is removed from the water the water returns to its original state ,assuming no leakage. Displacing the water at the bottom cancels out the energy that could be obtained by the flotation of the float.

Gearhead,
If the flotat enters at an angle higher than 45 degrees to the axis it is rotating from, it will move upward. It would take a lot of floats as well as a tall reservoir. This would allow for two or 3 floats being in the water at the same time.
The space between flotation devices can be sealed just like the floats themselves.
While it would be perpetual motion, it would be nothing more than a curiosity.
Sorry, but Gearhead is right. You misunderstand the principle of flotation. The reason something floats is because water below it is pushing it up. No matter what the angle of the float coming entering the water, there is no water below it to push it up, so it still has to fight against the water pressure to get itself into the tank, and there is not enough energy for it to do that.
There is no way for this device to work, even if you had a perfect seal.
heres a sketch of a chain of tanks......

But I do believe an inverted water wheel can work because the float would enter the water or medium at a downward angle to its' axis. And since it would be partially in the water/medium, it would be lifted.
This is the part I have an issue with. At the precise moment the float enters the water, there is no water under it to make it float. It has to be pushed in. It is not "lifted", as you say - that is an impossibility. This is easy to illustrate with a real world example. If you have a drinking straw of water that you are sealing at the top with your finger, you basically have a column of water with air under it. Why does the column not "lift" the air under it and draw it up? Because there is nothing to push the air up. On the other hand, if there was an air bubble in the straw, it would rise, since there is water under it pushing it up. I hope this is clear.
And do not worry about seals and friction. With a perfect watertight and frictionless seal, you still cannot get the float into the water, much like air does not just get sucked into the drinking straw in my example.
Regarding your underwater device; I am confused. Sure, it will work as long as the pressurized tanks supply air into the system. But what happens when the tanks run out of air?
G'day all,
Sorry guys, this kind of an idea has been around since 1825 at least in one form or another. There are any number of patents that have been issued for this sort of thing, none of which works.
For an explanation of what is involved:
http://www.lhup.edu/~dsimanek/museum/buoy4.htm
In fact the study of the entire site is recommended for anyone thinking about OU.
As to the air tank idea, where is the energy coming from to replenish the compressed air? At a depth of 10 meters the pressure required to blow the air tanks must be larger than 1kg/sq cm. And how do the top tanks fill with water, surely not through one small opening, it needs at least two for the air to escape so the water can enter and then the holes have to be large for the water to enter quickly enough in an area where water pressure is at its lowest.
Think again about it.
Hans von Lieven
The rotation of the larger belt drums partly powers a compressor.The compressed air also opens or closes large flood valves when required.Of course gearing would be required to run generator.Unit could be installed in a well.Or....
hm..
good point.....
G'day Rebel and all,
Something like this you can buy in almost every aquarium shop, there is no overunity in this idea though.
Hans von Lieven
this doesn't work.
Years back i thought of the idea of using water to overcome the problems of gravity.
I assumed that i had come up with a new idea, of using water and air.
I didnt have a good understanding of physics, but have a natural understanding of mechanics.
The whole wheel was completly under water, and was able to inflate with air and deflate automatically, so one side was deflating while the other inflated.
It was a slow process of filling and empting the air, when doing tests, so if the wheel did work it would have run extremely slow. ( in my dreams).
On paper it looked perfect, because in operation it was balanced, except for the air which should have pushed the wheel up.
but it didnt work, wasted a lot of time doing little mods to try to get it to work, but nothing helped.
After reading a few of the posts on this subject i now realise it has to do with the displacement of water or the pressure it took to inflate the bag, as it wouldn't totally inflate under water, but did in the air.
If i had done more research on the web and realised that other people had tried similar ideas under water that didnt work, i would have saved myself a lot of time.
so basically all i did was create a balanced wheel, an underwater chas.
Gravity machines # all explained to people that actually learned to understood the principle.
