It is a cheating presentation that does not work because the outlet water level is higher than the inlet level.
It is not the model of the device that was presented in the real world, in the link you gave previously:

It is very clear here that the setup is not that of the cheating presentation: the water outlet level is lower than the water level stored in the bin, therefore it works, it works according to the syphon principle, it's not free energy, it's not the model, the model doesn't work for the given reason.

In the syphon,
the water goes up from the excess air pressure caused by the difference in height.
Here it is pushed up by the atmospheric pressure, due to a vacuum in the tank.

I have no response. Only this draw to explain the principe.
Thanks

Don't think this diagram reflects reality because if you remove water in the
output, nothing will change - it is controlled by the surface area, not the volume.

In hydrostatics, they usually look at the pressure,  rather than the weight.
Because in the tank, weight is absorbed by the bottom, but pressure increases
with the depth, for example. at 1 meter it will be 1 atmosphere,
no matter how much water is there.
I will do some reading on it to understand better.

It's the same thing. The vacuum in the tank is due to the falling water.

I am always amazed at how few people on this forum actually know anything about basic physics.  The barrels of water can only work if the outlet is lower than the inlet.  The vacuum in the tank is working to stop the water from flowing out the same as it is acting to bring more water in.  The vacuum is measured in inches of mercury or sometimes in other units.  But the measure is for a given surface area of the water.  In this case the water is moved out of the tank because of the height of the water in the discharge line being greater than the height of the water in the incoming line.  This is called head pressure.  The higher the tank the more head pressure which comes from the weight of the water in discharge line in an area of a one inch column of water measured vertically from the top of the water to the actual output of the discharge line.  No matter whether the discharge line is 1 inch in diameter or 2 feet in diameter the discharge pressure is still the same.  You can just get more water through the larger line.

So the atmospheric pressure outside the tank is pushing down on the water outside the tank against the columns of water in both the intake and discharge lines.  The partial vacuum created by some water flowing out of the tank through the discharge line is acting on both the discharge line to keep the water from flowing out the same as it is acting on the water in the intake line trying to draw it in.  Since the pressure is acting equally on each square inch of water column it makes no difference whether the intake or the outlet is bigger than the other.  The only thing that will affect the flow is a difference in height of the water in those two lines.

NEVER GET YOUR EDUCATION FROM YOUTUBE!!!  Unless you are wanting to learn how to make fake videos.

OR THIS ONE .

Except here it flows from the lower level to the higher.

This is how Toricelli barometer works in real life.
"
The simplest kind of barometer is a tall closed tube standing upside down in a bath of mercury (a dense liquid metal at room temperature) so the liquid rises partly up the tube a bit like it does in a thermometer. We use mercury in barometers because it's more convenient than using water. Water is less dense (less heavy, in effect) than mercury so air pressure will lift a certain volume of water much higher up a tube than the same volume of mercury. In other words, if you use water, you need a really tall tube and your barometer will be so enormous as to be impractical. But if you use mercury, you can get by with a much smaller piece of equipment.
