It ain’t perfect but I’m tickled!
The steel tank will get etched and painted on a warmer day. Color doesn’t matter as much as darkness. The low angle sun of winter hits the tank, warming it. High angle summer sun does not (as much. These domes have been designed and initially implemented in Southern Colorado, Pagosa Springs to be exact, so the math/physics vary a little. That hasn’t stopped domers around the world from making it work!)
Did I mention how ding-dong pleasant it is listening to running water?!?! In the event that I have (ahem) I’ll begin tinkering with the solar fountain that keeps things moving. I’m reluctant to clutter the simplistic beauty of the dome, so don the thinking cap I do!
