Gravity Mill - any comments to this idea?

Hmm, I just came across this nice Cartesian diver applet:

http://lectureonline.cl.msu.edu/~mmp/applist/f/f.htm

Hold the red top with your mouse and drag it.

Can this be used to generate overunity energy ?
We only need to apply a short compression or release
of the pressure and then we could earn the whole
distance x  boyuancy force F as the energy output !

If we make the water volume very high, e.g. 100 Meters,
the distance it travels is pretty high and we can have
alot of energy output !

The input energy needed to compress the water is only a pulse and
can be latched when compressed and released ?

What do you think ?

The good thing is, you could put the electrical generator into the
water there too sealed and the diver would pull via a string the axis of the generator
via a clutch ratched mechanism and out of the container could
come already electrical energy via wires, so the only outside "control circuit"
would be a weight, that would be placed upon the water surface and
lifted a bit to release the water pressure.

stefan,

you have to stop.  you are telling people things that are not true.

let's start over with the basics.

if you have a fixed object that displaces 1 pound more of water than it weights, what will it do at 10 meters?  if you said rise, you were right.  how far will it rise?  if you said, all the way to the surface and expose 1 pound worth of its mass, you were right.  how deep can you take this object before it won't rise?  if you said, there is no such depth, you would be right. it has a fixed shape so it would still displace 1 pound more than it weights. any questions?

now, if you place this object in a tube, how high can the tube be above water before the object would not rise?  if you said, the distance that would contain 1 pound of water, then you would be right.  if we doubled the mass, but not weight, how far could the tube be above water level before the object would stop rising and pushing water out?  to answer this question, we have to have more info.  lets say our object is 1 cubic ft. (12x12x12 inches) and the tube is 10 meters long and fits the object snug.  for our work here, we'll say no water gets by in either direction.  if it is 1 pound less than it is displacing (fresh water), that makes it weigh 63.7 pounds.  now back to the question.  if you said, at least 12 inches plus enough for 1 pound, you would be right.  i doubt if many here really got this right.  if they did, it was probably for the wrong reason.  if the top of the tube were lowered so only 11 inches was above water, the object would rise.  not because it can push over 9 meters, 12 inch square of water weighting over 600 pounds, because it can not.  it can only push 65.7 pounds (1 cubic ft (64.7lbs) we increased the mass plus our orignal positive 1 pound) up.  so how can it rise?  the water coming in behind the object has the balance of the force due to the pressure exserted by an external colume of water, 12 inches square (the tube prevents any more than that to be applied), from the surface.  this is why if the object were removed, the water level in the pipe would be the same as outside the pipe.

it's getting late here now.  study the above and if you have any questions about what we just discussed, feel free to post here.  if all are clear, i will continue tomorrow with what i believe to be problem areas.

You are right here, but only, if this thing is not inside a pipe, so the water can also enter and flow
in and out from the side !

Hmm, I don?t understand this.
Could you please try to explain it with the example dimensions I used in my previous example ?
Many thanks.

Holy shit, this thing really works !

I just tried it in my bathtube !
The plastic-air-cylinder I had in a bit larger diameter tube (pipe) could lift at least 3 times
its own volume of water above it.. !
My tube(pipe) was too short, so I could not lift more water !
But it really works !

I have to go out and get some longer tubes ! This is really amazing !
If you go very deep you can really "pump" so much water with it upwards !
Now I also saw my fault.
As the hydrostatic preessure force is always bigger at the lower surface of the air-cylinder,
there is always a positive pressure and thus force to lift up the whole stack-volumeof water
above the aircylinder ! Thus if you have it 100 Meters deep, it will lift the whole 100 Meter column
of water above the aircylinder !
This has really a very big overunity factor !
Stay tuned.

Regards, Stefan.
