About Poncelet
The poncelet is a rare historical unit equal to 100 kgf·m/s = exactly 980.665 W. Proposed by French engineer Jean-Victor Poncelet (1788-1867) as a metric alternative to the horsepower for French engineering practice - the power to lift 100 kg at 1 m/s against gravity. Used in 19th-century French industrial and military engineering (waterwheels, steam engines, horse-operated machinery) before the watt replaced it. At 980.665 W, it sits between the metric horsepower (735.5 W) and the kilowatt (1,000 W). 1 poncelet = 980.665 W.
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.
