I was just wondering if anyone has made an aquaponic set-up which does not need electricity, be it doing it naturally and using edible aquatic plants or utilising the physical forces of siphoning and those associated with hyraulic rams?
Thank you for your help,
I've never tried it myself, yet, but something to incorporate somewhere, maybe.
Of course, energy's gonna be lost, so whatever momentum the ram pump recovered has to be started somewhere above it.
How bout a windmill to a water turbine?
This is an interesting project. When does construction begin?

Solar panel(s) + batteries + air pump + power inverter (if needed)

An air compressor, powered by an engine running on methane harvested from a digestor, that fills an air tank periodically. The air from the tank is released slowly into the AP system.
You are going to have to come up with a constant source of energy to do the work or find a source of energy that can be stored to perform the work as needed.

Water movement can supply the required oxygen. Most AP systems use a constant flow of water to keep a constant flow of oxygen and nutrients pumping throughout the system. IMO, the rope pump will need to be used more than one person will want to power it. Maybe get your friends to pump it. I think that a pond with a low stocking density of fish and a floating raft for the plants is the way to go without electricity.
Plants are the other source of oxygen, as already noted, and of course they consume nitrogen wastes out of the water. The need a lot of light to make lots of oxygen and added CO2 helps -- the pressurized tanks you see on fancy planted aquaria are typically CO2. You can find some pretty pictures of planted tanks with bubbles of oxygen coming from the plants when those things are there.
The problem is that fish eat and otherwise destroy plants and especially tilapia or whatever raised at aquaponic densities are going to make plant life hard.
I think you'll need some kind of power. Stock tanks are sometimes filled by means of windmills -- why not one of those? The setups are expensive new but maybe you could find one used.
The large valley where the Aztecs lived supported about 2 million people.
If you can get the oxygen level to remain high enough in the water a simple raft system could be built to just float around in an outdoor pond. Like what Lawton made in his recent video... but filled with lettuce growing out of cups like in aquaponics rafts.
This would shade the water and increase the "edge effect"... increasing the amount of life in the pond.
Also, you could concentrate wind in the pond area with three placement. Waves!
I have been thinking about a few chanells that exit and come back to the pond with part of them exposed to the sun. the theory is that water will get hot and then cool entering the shadow. I think it could create a slow current. Not enough by itself but maybe helpfull.
The low-tech version of the Integrated Aqua-Vegeculture System (iAVs) can be operated manually (ie...without electricity) using a bucket....if the system is small enough. A 'shadoof' or animal-powered pumping device can also be used. iAVs is irrigated four times daily (only during daylight hours) so it lends itself to non-electric operation....and to photo-voltaic solar operation.

Can someone help me to understand how to correctly install a link?
