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 Nanowatts
A nanowatt (nW) is 10⁻⁹ W - the power scale of ultra-low-power embedded systems. Cardiac pacemakers deliver sensing pulses at nanowatt levels to preserve 7-10 year battery life. RFID tags harvest ~10-200 nW from reader fields. Solar cells in wristwatches and calculators operate on ambient indoor light yielding tens of nanowatts. A standard AA cell (13,500 J) discharged at 1 nW would last over 400 years. Neuromorphic chips target 10-100 nW per neuron-equivalent circuit. 1 nW = 10⁻⁹ W.
