ONE SIP OF COFFEE Excerpt

I was intrigued by the following question: How long would you have to scream to provide the energy to heat up a cup of coffee?

If you make a few assumptions about the person screaming and the beverage involved, then the answer is a year and seven months! I found that timespan to be quite astonishing and revealing about the energy density of hot drinks which we consume every day.  Imagine the duration of a scream that powers your phone, your laptop or even your transportation to work.  The motions that power our daily lives are the result of a multitude of dramatic unseen energy transformations.
