Pulser pump lifted water 6 meters to soldier's quarters in the Alhambra castle 600 years ago!

In the last couple of years, people have speculated that, at the Alhambra in Granada in Spain,  they were using a trompe to power an airlift pump to pump water to the soldiers in a castle keep 6 meters higher. 600 YEARS AGO!  The pump had no moving parts!   This month a guy went further and suggested in video that it was a pulser pump, and he made a model and it is at 1.5 million views and rising after 2 weeks!      
I introduced the pulser pump to the modern world in the 1990's.  It's a low pressure trompe that powers a low pressure airlift pump with pipes optimized for slug and plug flow. The key is that it is optimized for these types of flows, because these are the most energy efficient way to move water with air.   Other airlift pumps work because bubbly water is less dense than water without bubbles, and therefore a column of bubbly water is higher.   I put the pulser pump on the internet in the 2000's.  It went on youtube and other video services in 2006.  But even with video evidence that it worked, people still called me a liar.  Here is one of my pulser pump videos.  


And here is the guys video, with a pulser pump model,  that got 1.5 million views so far.  


My problem is that even though he didn't credit me, he took a screenshot from one of my videos, and he made a bad model of a pulser pump.  If he had looked properly at my videos he would have made a much better model.  Also, it is as if my useful info was censored, it never made it to the 1.5 million new people.   Youtube demonetized me nearly a decade ago, so my videos will never get viewers again.  If you read comments on his video, nobody has learned anything from my real pulser pumps from as far back as 1990.   None of my real info got past the BS of people trying to guess how it works and how "inefficient"  it is.   The other video about the Alhambra pump was even worse,  it had an animation to show how the guy thought a trompe worked and how he thought an airlift pump worked.   The animation has very little in common with reality.   My pulser pump had 4 inch pipes, had power water that had a head of 0.5 meters  and was 250 to 350 liters per minute, went 2.5 meters deep and pumped water to 3.5 or 4 meters to the cattle and to 5.5 meters to the sheep.   The thing is, it could pump much higher,  at least to 8 meters high.   I also had a pulser pump with 6 inch pipes (to test if that would be better)  but it only ran when the stream was in flood, so I never got to test it properly.  So, anyone out there in the Permies world who is monetized and who wants to prove that an Alhambra pulser pump worked?  Here is what you need to do.  Make a pulser pump with 6 inch pipes in a swimming pool or something like that.  it needs to go 2.5 meters below the surface, and its airlift pipes need to go 6 meters above the surface of the pool water.  Airlift pipes would be probably 1 inch pipe.    I am putting in an image for guidance.  You don't have to be exactly like the image,  but close to how it is, is best.

Brian, I am having trouble understanding you drawings.
But I saw this Youtube some time ago that describes lifting water with air bubbles using falling water and a whirlpool created with engineering, air was sucked into the water causing the areated water to rise up a smaller diameter pipe because the kinetic energy in both parts of the system was the same. This would allow water to rise in small volumes 6 Metres.

 
This. Exactly this. This is what my therapist has been talking about. And now with a tiny ad:
