But it works only under a set of specific circumstances. And copper can work to stop that last method of heat loss. “This leaves only radiation heat transfer between the walls,” Johnson said. A double-walled bottle already stops solid conduction, and a vacuum-insulated bottle stops gaseous convection. 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.
