History of the trompe on French Wikipedia (very detailed)

[Brian in Victoria BC]

My "pulser pump" was considered by many people to be "fake" in the early 2000's and they would routinely get quite upset and call me a liar on the internet. Partly because nobody had a clue what a trompe was. (A pulser pump is just a mini trompe providing the air for a mini airlift pump, and people struggled with the concept of a water pump with no moving parts). So, I went to english wikipedia and created the airlift pump and trompe "stubs" and asked for other (with access to university libraries) to provide the references. Within about a week, both pages were live with references! I was impressed! But they never really evolved. And the airlift pump page was taken over to some extent, by the inventor of the "geyser Pump" to direct people to his product. The French trompe page is far more interesting. It has 32 pictures! It has a superb history of the trompe, from the persian water bellows around 300 AD to Genoa around 1600 AD, then the Catalan forge, and later the giant underground trompes of the late 1800's. So yeah, check it out. I believe that mini Trompes should return, as a device to remove gasses and sediment from rivers. I will explain the why and the how if there are replies to the thread. Web browsers convert this French wikipedia link to English very well!

A high siphon will "cold boil" the dissolved CO₂ out of the water at the crest. That can block the liquid flow through the siphon. Keeping the siphon cool, out of direct sunlight, should maximise the height by reducing the partial pressure of CO₂ and of H₂O at the crest.

A trompe operates on the other side of atmospheric pressure. It tends to maximise the atmospheric gasses dissolved in the water. That is a benefit for furnace operation, which might otherwise, be extinguished by the CO₂ extracted from the water. The same is true of an inverted siphon that has no atmospheric limit on height.

I would like some way to operate a multi-stage tromp, to get higher pressure than one head of water. The problem comes in the reduction in hydrostatic pressure while returning the water to the top of the hill. Must I use one stage only, with brine, drilling mud, or Hg, as the fluid?
