About Petawatts
A petawatt (PW) is 10¹⁵ W. Total solar power intercepted by Earth is ~174 PW. The world's most powerful laser pulses operate at petawatt peak power via chirped pulse amplification (CPA, 2018 Nobel Prize in Physics): China's SULF demonstrated 10 PW in 2019; ELI-NP targets 10 PW. These PW pulses last femtoseconds and create plasma temperatures of billions of kelvin in laboratory targets. Gamma-ray bursts radiate 10²⁴-10²⁷ W at peak - thousands to billions of times the petawatt scale. 1 PW = 10¹⁵ 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.
