Answer 1

Its not the material of the cups and coolers that keep things hot or cold for so long, its the design.

That design revolves around creating a barrier inside of its walls that is a complete vacuum. No air or material of any kind that could transfer heat from the outside of the cup/cooler to the inside and vise versa.

This creates many problems when trying to design such an insulation for a house. Breathable air for example.
