Hi Stephen:

There are several members of the RGGS group that have incorporated it into the system, with several more planning on doing it in 2015. Personally I haven't but am aware of it. I am currently working on plans for erecting a 30' diameter geodesic dome for greenhouse growing, and part of the passive system for heating and cooling includes a pond within it which will also be aquaponics related...so will serve dual purpose of temperature control as well as the aquaponics for a portion of the plants within the dome.

Thanks for asking and looking at the system...personally I find there is nothing more pleasurable than being able to pick and eat fresh.
