About Terawatts
A terawatt (TW) is 10¹² W. All of human civilisation consumes ~17-18 TW (electricity + heat + transport combined); global electricity generation alone is ~9 TW. Solar irradiance intercepted by Earth is ~174,000 TW; photosynthesis captures ~130 TW. The National Ignition Facility (NIF) fusion laser produces pulses of ~500 TW lasting nanoseconds. High-power laser facilities for nuclear physics and ICF research routinely exceed 1 TW in ultrashort pulse regimes. 1 TW = 10¹² W.
About Calories per Second
One calorie per second (cal/s) = exactly 4.1868 W. It bridges thermochemistry and power: bomb calorimeters and reaction calorimeters characterise exothermic events by cal/s during the reaction interval. Food science uses cal/s to model heat transfer into food during frying or roasting. Since 1 kcal/s = 4,186.8 W, kilocalories per second appear in high-intensity industrial dryers and continuous-flow reactor heat duties. 1 cal/s = 4.1868 W.
