The ongoing supermassive thermo­nuclear explosion that powers the sun emits energy at a mind-boggling rate exceeding 100 trillion trillion watts. At a relatively safe distance from the sun of some 93 million miles, Earth receives just one-billionth of that colossal energy flow. But even that mi­nute fraction, 120,000 terawatts (120,000 trillion W; 1 W equals a joule per second), showers Earth with more energy in one hour than all the energy consumed by humans in . . .
