capillaries and energy conservation

[deschoe]

As you can see in these following videos, capillaries are able to suck little waterhills in the surrounding areas of floaters away, so that a floater in a capillary rises more than a floater outside a capillary.

For this you can create a circulation between the two floaters, that creates energy, but the question is, where does this energy come from ?

here is the 111 sec version :

and here the detailed explanation :

Please let me know, why do you think this is compatible with energy conservation as far ?

Sometimes actually calculating it might be difficult, but remember that conservation of energy is never violated.

 

For the example of the rotating ring, it is simple: since there is no change in potential energy between two positions, there are no net forces on the ring, and therefore it will not move.

and whats in the case with the cubes ?

Intrigued, I thought about it some more.

 

The pressure in the liquid depends only on its depth and the capillary action above it has no influence. That means that two identical stacks of cubes would float at the same level, because the pressure at the bottom of the stacks has to be identical, whether or not they are in a capillary.

the pressure under a wave is higher than the pressure under the area outside the wave and the little waterhills in the surrounding area of a wooden floater is like a permanent wave.

as I said, if you have a permanent wave at a tiny devined place, you have a different pressure at this two places, and for this, two floaters ( cube stacks ) at these places have different levels, ... and than results .... (watch the videos if you dont know what results )

A wave is dynamic. It attempts to restore the pressure difference by moving water from high pressure to low pressure. If the pressure below the little waterhills was higher than around it, water would be moving. There could be deviations close to the affected surface, but not deeper underneath.

[deschoe]

the thing with a wave was only an example : https://books.google.de/books?id=hupZaqROt9QC&pg=PA18&lpg=PA18&dq=pressure+under+a+wave&source=bl&ots=dGLKNHXjWv&sig=nR0gAyl_Bk9lWUryBDn-BXktzLY&hl=de&sa=X&ved=0ahUKEwi_mKjThvHQAhWEvRoKHZX3DA0Q6AEIHzAA#v=onepage&q=pressure%20under%20a%20wave&f=false

 

But I hink I have to explain this once more. One floater in a capillary has a higher evel, than a floaer outside a capillary, because there is a additional weight ( the little waterhills in the surrounding area of the floaer outside the capillary ) that keeps the floater outside the capillary down.

and to build a mechanical system that doesent need a human hand, it costs about 200000 $. its like to make a watch for the first time, means you have to make every single part as a custom made.

What is the wave thing an example of?

 

The video doesn't even show a device as described that does need a human hand. The video shows some irregular floaters attached to a lever that is not shown. Some undefined blocks are displaced, which is clearly a mechanism that can only be repeated a handful of times at most. Where do you get the seemingly arbitrary value of 200000 dollar? Do you have a detailed design?

 

I certainly wouldn't spend that much money (or any money, really) on a device that contradicts the first law of thermodynamics.
