Trompe !!!!!

I've not seen this before. I think it's worth exploring.

I'm just pasting all the information I can find out about it, but there aren't much around even on google.

Great find very nice!

But would the collected air pressure be enough to pump the water back to the input?

I think this is what this guy is trying to do: https://www.youtube.com/watch?v=xv1lQA-tnwo

I do not think it's the air pressure that's pushing the water back. The collected air pressure is simply a side-effect of this process.  Gravity is the one that is responsible for pushing the water out the exit pipe.  The input pipe is higher than the output pipe. I believe he stated that a difference of one meter between the pipes is all that is required. Unfortunately, His drawing was terrible and hard to understand why it works, but I found an illustration that depicts the design he was talking about.  The principle is exactly the same as the ones posted on the other website.


It appears to be a technology that was forgotten or buried as he claimed,  but the physics/idea is solid. I just happen to come across this purely by accident when I was randomly clicking on youtube videos, but it gave me the feeling that this is important.
