    I am interested in utilizing more efficient technologies to improve production of healthy food.
  1. Is anyone here experimenting with this? I am currently constructing a aeroponic/aquaponic hybrid system indoors. My plan incorporates 80 planting sites utilizing both horizontal and vertical channels. My first stage is almost complete. It includes a 100 gallon reservoir, a vortex filter, a 4200gph external pump, a manifold to divert water to each of the three growing areas, the main line which feeds the giant independent wet/dry filter (which take the brunt of most of the water flow), and the first 28 planting sites. I am utilizing a large pump to maintain water quality, increase aeration, increase my Nitrosomonas and Nirtobacter cultures, and to later expand my system. The large pump has relatively low power consumption given its flow rate and I do not expect that I will need any other equipment to maintain excellent dissolved oxygen levels. The nutrient delivery to the plant sites is controlled by the spray jets inside the channels. Mind you, I am aware that this is not a high pressure aeroponic system, but I liked the idea of testing a misting environment that used no growing medium. Any insight would be appreciated. I have much more experience with fish than I do with plants. I am doing my best to learn, experiment, and improve.
  2. 'Only by optimising the water quality in an aquaponics system, can you maximise its productivity, and you can only optimise water quality in a small aquaponics system by removing the solids.' Bravo!
  3. I understood that while utilizing a UVI model, 80% of power consumption came from aeration. My initial thought was inefficient use of the pump. wouldn't you be able to almost, if not completely, eliminate the need for additional aeration if you utilized spray bars, venturies, and waterfalls in the system? None of these would require additional power consumption and they could add massive amounts of aeration.
  4. I have been exploring this concept for quite a while now. Everyone usually has the same answer. My challenge is this: Why is it so rare for people to consider the energy contained within the magnets that are being turned in the generator to extract the electricity? You can build generators with extraordinarily strong magnets, some of which are said to retain their magnetism for 400+ years. So... if you combine the energy of the moving water with the energy contained within the magnets themselves, is it still impossible to extract energy in excess of that which is being created by the movement of the water?
