What «other video” are you referring to? This video is debunking the claim that a barrel “pump” can lift water to a higher level with no energy input. There is no reference to any bell siphon.

The purpose of this video is to show that no siphon «pump» can lift any water to a higher level. So it does. Excellent video.

Noop, would not help. The point of this video is to show that this “pump” is fake. Can not work. He explains why it does not work. If it did it would be a Perpetuum Mobile.

@kjellg6532 his lid is not even air tight. he did not even begin to build it correctly, therefore how could it work? if you believe this, you clearly have no hands on experience, but believe what you will. it makes no difference to those in the real world.

@@ansuz444 well, in fact I have been using a siphon for more than 40 yrs. In this video yoy clearly see that air is sucked in via the exit side. This is due to exit being higher up than the water level in the source. This set up inn the video simply can not work. Water flows downwards, not up in a siphon. Exit must be lowervthan the input. To lift water, you must add energy to it. Here is no energy source so no water can be lifted.

@@kjellg6532 and yet, delicious milkshakes still work. yom yum

@@ansuz444 Yes, milkhake may taste good, but no siphon like this is capable of lifting water. This is not a pump.

That is why middle bottle or barrel needs to be AIR TIGHT, dummy 😂😂

@@ThereYouAreT1 lol the only way for it to be air tight would be to close off the outlet pipe that is where the air comes in from.You did make me think of something that might make this work tho. If you would take an aquarium air stone and plug the bottom pipe with it and let the air be suct through it that might atually cause it to work.

@@ThereYouAreT1 Now, if this setup could work, you could create a hydroelectric powerplant in your back yard. You just take water from the swimming pool, lift it up in thin air and let it fall back to the pool via a turbine/generator. Electric power free and forever. That is wat you clame! Up till now nobody has ever made a working Perpetuum mobile. Do you know how to make it? Just by closing a lid?

He understands and tells the physics very well. He proves that no siphon can lift any water to a higher level due to no input of energy. Try to lift water over som time and you get exhausted.

Yes a nice palace, but do the Lions clock work? I do not think so. Does the 6 m pump work? Probably, but the video only tells half the story. Not a single word about all the waste water and how the waste is getting out of the system. Look up Trompe, Air lifting pumps and Pulse pump.

The Alhamra Trompe and Air lifting pump is a totally different issue. Combining the two you get a Pulser pump: en.wikipedia.org/wiki/Pulser_pump A Pulser pump works, but not as described in the video you linked to. The video here is debunking those who clame that a siphon can lift water. That is impossible, as shown here.

This excellent video shows that for this system to work, the orifice of the exit from the system must be lower than the water level in the source. Diameter of this orifice does not matter for the system to work, but has influence on the amount of flow.

It will stop at the same height as the source. No siphon can lift any water to a higher level. The input must always be higher than the exit from a siphon.

This video is excellent, tells why these „ pumps“ are all fake.

Also look up kzbin.info/www/bejne/fHmtnoybe9B9i5o a variant of ram pumps that is less noisy. They both are good pumps that lasts for decades. But, the can not pump any water up from a well. They need a certain head and flow to power them.

Sorry, but no. When using a tank you do not need any one-way valve. The tank here is air tight, just watch the video. If the output is longer, horisontaly, it will not help. If the output is longer vertically the whole point in pumping water to a higher level is gone. This excellent video debunk the “drum pump” as fake, and explains why it is fake. The drum pump is a siphon and no siphon can lift water to a higher level.
