If YETI can make a cup that keeps water cold or hot for hours and a cooler that holds ice for hours, then why aren’t we building houses with that same material?

We do, they are called [Earthships](https://www.youtube.com/watch?v=wVp5koAOu9M). 6 foot walls surrounded by 4 to 8 inches of insulation. Roofs sometimes 14 inches thick of insulation. Double walls before the interior living space. Big learning curve, but they feel more grounded, embraced and balanced living in. I actually have many Yetis for us while building our Earthship.
