Scott_Garrett asked about the Devil Can. It's overly complex. I have an explanation but won't go into it.

Love it! Thinking about adding one of these to my display next year.

Very cool.
You are right it is complex bit it clearly works well.
I particularly like that you put in underground air, power and control cables for it.
