Imagine this. A refrigerator/freezer that has no doors, but works just like a regular one. This way you could stand there forever browsing the contents without wasting energy, and you could grab things at your leisure! I'm sure it's technologically possible to do this now, with, I don't know, electro-magnetic fields and whatnot.
Reward: A free one of these things.
