Rocket mass heater in walipini greenhouse for supplemental heat?

It's been a while since I've posted here, but I had a thought and would like some feedback on it. I'm very interested in walipini greenhouses and I've been thinking about how it would work to install a rocket mass heater along the back wall of a walipini and sit large water tanks on the bench part of the heater. The tanks could have fish growing in them with the fish water used on plants growing toward the front of the walipini, does anyone have thoughts on the feasibility in a system like I describe? Do you think it would be worthwhile to build something like this?

That very subject has been discussed here in the past month or so (couldn't find the link just now though). Search for rocket greenhouse and you will find a bunch of threads that are relevant - the fact that it is largely underground is only slightly material. It would probably work best running down the center rather than against the back wall, unless you have a very skinny space. Radiating and conducting a large part of the heat to the exterior wall doesn't seem effective.

Mark A : As I understand it You are on the right track, You are also in the right part of the country ! You should post something about your plans in the Forum / Threads

Also if you research under Aquaponics there are several URLs that come up, good for general information, after you find a local Aquaponics supplier it should be a short
step to finding someone who is out there ''Doing'', I would recommend that you take this winter to shadow a successful fish raiser and learn as much as you can about
how to build a Walipini for your latitude / location / climate

Your project Is doable but it certainly requires you to have a

1) Green thumb- container garden variety
2) Greenhouse experience
3) underground building knowledge/skills how do you deal with water issues, where do you want insulation
4) Rocket Mass Heater experience
5)Aquaponic experience, there is a fair amount of understanding chemicals and Ph balance and the need for pump assisted water circulation, for oxygenation
and of cource knowing what goes in at one end of the fish, and how to use what comes out the other end- back to chemicals again !

For the Good of the Crafts ! Big AL

Thank you for the great responses; I will do a lot more research before I start digging and I'll check out the forum threads mentioned.
