This is something I wanted to do since before the first Mother Earth News.
"Aquaponics (pronounced: /ˈækwəˈpɒnɨks/) is a sustainable food production system that combines a traditional aquaculture (raising aquatic animals such as fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a a symbiotic environment. In the aquaculture, effluents accumulate in the water, increasing toxicity for the fish. This water is led to a hydroponic system where the by-products from the aquaculture are filtered out by the plants as vital nutrients, after which the cleansed water is recirculated back to the animals. The term aquaponics is a portmanteau of the terms aquaculture and hydroponic." This would be especially good if the land is dryland.
We might still like electric power and we might get. at least some for "earth batteries". The first earth battery was built by Alexander Bain in 1841 - oph! what about the "Baghdad Battery"?
The Baghdad Battery or Parthian Battery seem to have been used in the time of Jesus Christ.
Need to look into the Earth Battery more!!
If you are wondering how this post got to batteries, We need to have electric to power the submersible pump to cyrculate the water from the fish to the plants. It's gravity feed though the plants to the fish.
