Is it possible to have a material that transmits infrared in one direction but not in the other? There are a few articles available that say it is, though I don't have any here with me now.
So, let's say you make a hollow sphere of this material, oriented so that infrared light can pass out of the container but not into it. Would that make anything inside of the sphere very cold?
Edit: removed misleading reference to a "one-way mirror"
