Actually, he poses a very sound question. We know what a watt is, we know what a watt-hour is (watts times the hours it was on), but what an watt (work per time) divided by hour (unit of time) means is beyond me too. Kind of like acceleration for work done perhaps? E.g. in 1 hour it improves its performance 60 times?
