- I agree with John H from NY (11/4): The description of the "Watts" as what's used is misleading. Watts is a measure of a *rate* of energy use/transfer. Watts is to velocity as energy is to position or distance traveled; it tells you how quickly you're using energy, not how much you used. You could have said that resting people use energy at the same rate as a 90-W light bulb. But over a specific time interval, like a day, that's energy - kilowatt-hours (kWh, what you pay for in your electricity bill; using energy at a rate of 1000 W for an hour means you used one kWh). kWh are the same beast as BTUs and Joules, too - it's all energy. Love the show, but as a researcher on conceptual difficulties in physics, I notice things like that. Overall, you guys do a great job explaining things at a layperson level while keeping the essence of the science intact.
