Aside from vacuum flasks and vacuum insulated panels, there doesn't seem much else vacuum insulated. Why are there no ice chests vacuum insulated?
My uneducated guesses as to why ice chests are not vacuum insulated:
1. Cost to vacuum insulate.
2. The cylindrical shape of a flask offers greater pressure strength.
3. Ice chests take a much greater beating than flasks.
