No doubt GW...I'm pretty excited about it. I love being able to incorporate ecological/environmental loops into my farm. Obviously you can't have a farm with a completely closed loop if you have production going out but you can certainly recycle and be highly efficient. I know a couple universities are doing some large scale studies, but I don't know how large. Right now I have upwards of 75# of mixed vegetative/animal sourced organic matter per day that needs to be composted/recycled ... If the system works and can be made efficient I have the resources (read manure and animal entrails) to double or triple that amount in time. Come spring I'll touch base and let you know how things are working out.
