Last year, as energy prices rose, I was appalled by fluffy and just wrong pieces in the popular media. I started counting instances where energy and power were mangled and gave up at fifty in less than two months.
Horsepower is not a quaint leftover of linguistics or a vague metaphoric anachronism. James Watt, father of the steam engine and progenitor of the industrial revolution, lacked a measurement for the movement of weight over distance in time—what we call energy. (What we call energy wasn’t even an intellectual concept in the late 18th century—in case you think the recent collapse of global capitalism was history’s most transformative moment.) Mr. Watt did research using draft animals and found that, under optimal conditions, a dray horse could lift 33,000 pounds one foot off the ground in one minute. Mr. Watt—the eponymous watt not yet existing—called this unit of energy “1 horse-power.”
