The more I learn about aquaponics, the more I realize that there are many, many "ways" or designs that will construct aquaponic systems that work. I love the innovation in this field right now--- so many interesting ideas.
This strange system totally fascinated me, so I'm going to post a link to this gentleman's description of how you can build an aquaponic system that uses no electrical pump of any kind. That's right.. NO ELECTRICITY IS USED.
His target of course, is very poor parts of the world, or remote locations-- that still do not have electricity--or reliable electricity.
Check out his rather sketchy, step-by-step instructions AT THIS LINK, and let me know what you think. Seems like it would require a human pump... for at least a couple hours a day, but do you think this is a feasible aquaponic solution for people who do not have electricity?
