I wanted to take the time to say thank you for all the information you freely share on your research. In the past month I have come across your comments and videos for 3 unrelated topics and you helped me understand each one better. Cheers

clay- sand- lime- wood ash 4-6-1-0.25
wood ash we just started using on the last roof.
i am adding limewash every year for now.

You are on to something there...but that still needs measurable head pressure that is sure to get noticed on a flat ditch. Could it be submerged in a total depth of 1/2 meter with siphon outflow at the base? I think i could do a divot in the stream bottom that would not get noticed...hmmm

I am really surprised at the dearth of info on pumps on Permies. Aside from getting water with your property, how to move it seems to be the next big thing that we deal with in design. Not everyone will be so fortunate as to have a site on a slope from top to bottom with enough 'head' to make a RAM pump work. So what's left? Grid driven electric? Fuel driven electric? Solar driven electric? Hand power? Gravity?
What I have discovered is that a RAM pump is pretty cool, but takes at least 18 inches of head pressure to run, And then, very slowly. This means that a storage tank or basin will be required in addition to 'head' Or you will need to use a water wheel of some sort. In Boise there is a lifting wheel design on display that was used years ago before electricity. Nothing else?
Windmills, manual or electric? This means storage too.
Screws, Siphon, Sprials...the Rife River Pump (no successful copies by DIY yet. No testimony by Permies on these either! Still storage issue.
I guess this is one of those places where electricity driven pumps is the most AT?

Imagine adding air entraing.
The plastic could not handle it but a concrete 'tank' could.
I think a heavy duty tank would let the air escape the water but the water should still have its energy
I no longer have access to the family farm so I can't experiment any more with free flowing water.
I'm all for old tech finding new uses.
A epa engineer is using the air to oxidize heavy metals.

But I can see it for back to the land movement
Any micro hydro instalation can be modified slightly to produce air pressure.
Just add air intraining
Put a tank next to the generator......
