Love the natural look! Like an undersea gardenthats a great tank, I learned more about Peltiers than i ever wanted to know haha. They exist up to 500 watts now so I think a native tank nano all in one is possible. i have this little tank set up with a few thing I have collected.
I had an idea to try and capture energy loss from high voltage power lines using peltier units and capacitors but couldn’t ever get it to work :/
