So, “the copper liner needs to be: polished, installed in a vacuum, and done so in a manner that limits the amount of oxidation of the metal prior to pulling the vacuum. “The main benefit of copper is that when it is polished, it is much more reflective of radiation heat transfer,” Johnson explained. But it works only under a set of specific circumstances. And copper can work to stop that last method of heat loss.

A double-walled bottle already stops solid conduction, and a vacuum-insulated bottle stops gaseous convection. Replacement cap compatible with the ICONIQ 17 Ounce Insulated Water Bottle (Water Bottle Not Included). It could work, and as Wesley Johnson, a cryogenics research engineer at NASA’s Glenn Research Center in Cleveland, explained, “For spacecraft, we often use a similar technique for insulation.” The theory behind using copper in insulation (despite its being an excellent conductor normally) is based on the fact that heat transfers through three forms: solid conduction, gaseous convection, and radiation, Johnson told us. Best filtered water bottle for tap water. Sometimes manufacturers make bottles with copper linings in an attempt to keep the contents even hotter or colder.
