The way a trompe harnesses the power of water to generate compressed air with no moving parts is fascinating and its use is seeing a small revival in modern days. A trompe can be useful in off-grid aquaponics and hydroponic systems that need aeration of the water. And, in fact, the inspiration for this video came from the late Bruce Leavitt, a mining engineer who pioneered the use of small trompes for aeration and treatment of mining water in remote locations without access to electricity.

I found the air bubbles in the first tube of the model to be strangely soothing. Have no idea why.

A 351 foot drop produced 120 psi. I can find no mention of volume (cfm), but judging from the diameters of the bores, one can surmise it was substantial.

And it produced dry air which sounds counterintuitive considering all the water involved in compressing it.

I never heard of this idea before, but it's something I will file away in my brain to chew on because, well, this sort of stuff always intrigues the shit out of me.
