 Okay, so yes, and there was something, I had the idea and I don't know if this is existing somewhere for creating air to move and that is something what is mimicking the air conditioning of a zebra. You know zebras with the stripes and you know why the stripes are vertical so the black will heat up and the white not so much so they create a micro climate that is cooling down the zebra a few degrees and so for buildings you can also have sort of a zebra design so black parts will heat up and so you create sort of air moving and air moving will keep a building cool.
