A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

If so that means moving a block of ice has negative heat efficiency. Sounds like nitpicking to me.
