One thing did occur to me right before I decided that this is not practical....
With my Tilapia experiments, I am going to be using oxygen and ozone...The stocking rate will be so high that I'm going to need backup power in case of power loss. So, if I set up "whatever" generator, I could use a smaller one than I would otherwise need, and I could use simple manually controlled valving to direct water, or even simpler, just install the generator in the utility room where I am going to have all of the sumps. It wouldn't be any different then the space heater I have next to my 55gallon barrel that I'm using for a sump right now...
We don't all have perfect ideas all the time....but it takes "way far out" ideas these days to get anywhere. I come up with them pretty much every day. But a lot of them are more like "what are you on?" than just being a little far out. LOL.
