ENERGY, POWER, PRODUCTIVITY, SCALE: The Continuing Quest for More Bang for the Buck—or "A lot of good arguments are spoiled by some fool who knows what he's talking about." ~ Miguel de Unamuno “It wouldn’t have dented a grape,” the sportswriter Jimmy Cannon wrote of Muhammad Ali’s anchor punch that dispatched Sonny Liston in the first round of Maine’s most famous sports event just a few miles up the road in Lewiston. That was nearly fifty years ago. Today, the earth continues to spin nearly 1000 mph on its axis as it moves around the sun at nearly 70,000 mph, while the sun itself is pulling its system through the galaxy at 52,000 mph. Our Milky Way is moving through space at 515,000 mph. The second most amazing thing I know is that all of space and everything in it, today stretched to a diameter that would take light moving at 186, 000 mps 13.8 billion earth years to traverse, was, 13.8 billion years ago, trillions of times smaller than a grain of sand. Holy density. Our species emerged around 175,000 years ago—and most of us are built out of seven billion billion billion atoms—that’s 7 followed by 27 zeros, two-thirds of which are hydrogen, 24% oxygen, a bit less than 10%, carbon. And the stuff from which atoms are built is many magnitudes smaller still. The range between the largest large and the smallest small is nearly incomprehensible. Who knew? I present these details because, in a society so heavily dependent upon arcane knowledge, we take for granted the wonders around us and too often, for the sake of happy talk and a kumbaya sense of getting along, pretend to know what we don’t in ways that contribute to the coarsening of our cultural discourse and imperil our wellbeing. Take the case of energy. How often have you heard people say we need more energy? Or conversely, we need to use less energy. Or that we must achieve energy security. Or that we support renewable energy. The underlying assumption is that they know what energy means and more importantly how it relates to their quality of life. What does energy mean? And how does it correspond to the notion of power, which also has its share of admirers who banter such terms as “windpower” around as if they understood it—and as if it were true. The basic nature of energy is still not well understood. Aristotle used the term ergon millennia ago to describe basic activity. Today, physicists use the word to describe the capacity for movement or exertion between one state and another. We know energy exists in both potential and kinetic guises. We also know it can change into many forms while varying from the highly diffuse in the vacuum of empty space to incredibly dense neutron stars, their crusts ten billion times stronger than steel. Energy is intimately related to heat, which in turn is best understood as energy in motion; its behavior is described by the laws of thermo dynamics, beginning with the famous Three Laws, the last of which states that our universe can never achieve absolute zero; quantum jitters assures there will always be movement—and Page 1
