Thank-you for commenting that because I hadn't considered that

Though I do think tempreture control can be done with technology supplementation

For example having technology read the tempreture in an area and then close a vent to stop natural cold or hot air once the desired tempreture is reached

Edit: and have technology supplement cool pr warm air if there isn't enough of that from natural air

And I am wondering how much the air tower itself can be made smaller while retaining function
