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 Exawatts
An exawatt (EW) is 10¹⁸ W. The Sun's total luminosity is 3.828 × 10²⁶ W = 3.828 × 10⁸ EW. Earth intercepts ~0.174 EW of solar power. Gamma-ray burst peak luminosities reach 10⁶-10¹ EW, making them the most powerful transients in the universe. Soft gamma-repeater (magnetar) giant flares briefly reach ~10⁵ EW. Proposed multi-exawatt laser projects (IZEST initiative) aim to compress kilojoules into attosecond pulses for QED vacuum physics. Global human civilisation consumes ~1.8 × 10⁻² EW (18 TW). 1 EW = 10¹⁸ W.
