Looking for people world wide who will openly discuss and develop "Tromp" or "Tromble" pneumatic systems. This technology has been around since at least the iron age, I believe, my dates could be incorrect. This kinda tech isn't hard to understand nor does it have any moving parts, except air bubbles and flowing water.…
that link will take you to Bill Mollison, the father of permaculture, explaining how a tromp works. So any taker out there?

Ronnon. Have you tried to do this?

Yes. I've built a small model to test. The usa dept of interior is currently looking at building these on heavy metal polluted water ways in usa to remove heavy metals cheaply. They are not however telling anyone that it make clean renewable energy in the process. It order to get a usable volume, I would have to scale up beyond my monetary means.

This tech was used in deep mines to power drills, provide cooling for miners and supply fresh air.

In the small model, or big model, how do you store and transport the cold air?

Small. I used a 134a bottle as my reservoir. My model only proved to me the concept. I was only using 30' of drop. A commercial build would need to be maybe 75-150 meter drop. The air is isothermic and pressurized variable of head pressure.. So the air isn't heated because the air bubbles are compressed in falling water column. The air can be intensified using simple intensifier tech to say 100 - 100 psi and stored in cylinders. So no volatile fuels, and no huge batteries.

1000 psi, not 100

I'm really low level on this kind of stuff... so you would have a release valve on the reservoir of air, or close to if the intensifier is there. Then it goes in the giant cylinder barrels. What are these barrels useful for? Household appliances? I have a tiny home in my mind

Also what is a 134a bottle
Sunday 23 July 2017, 16:24:37
Sorry, I'm a mechanic lol. 134a bottle is used for freon for vehicle air conditioning.

As for use, 2 cubic foot cylinder could power a car for say 200 miles. That is not a large cylinder. So instead of electric cars that take all day to charge, you could simply swap cylinders in vehicle, or fill up like a standard petrol vehicle.

The air pressure from you underground reservoirs on large systems could be stored in cylinders, or piped to home much like gas and water mains.

Long story short, anything petrol can do, pneumatics can do with no polution. It would just require the infrastructure be built.

Here is a diagram of a simple tromp

That diagram makes it tooooooo easy!! Thank you for sharing
