Generally the issue is space/foot print. The efficiency energy wise is usually pretty good, but the amount of space vs what area gets covered (and this is forgetting bells and whistles like actually controlling the temperature) is usually abysmal. This only works on a small scale for few people that are willing to forgo accuracy and control.

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
