Makes sense Bruce. I'm sure the RAS guys would also be someone to talk on how to do it most efficiently if you did do it. I have a PHD friend that raises hybrid striped bass indoors I could pass this by with and see what he has to say if you're interested. I believe he puts his water in a large tank first and allows the ambient temps of the building to do some of the warming. And of course he reuses the water. Seems like if you could insulate and isolate the area of the building and reuse your water it would become an easier goal.
If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
