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 Foot-Pounds per Second
One foot-pound per second (ft·lbf/s) ≈ 1.3558 W - the natural power unit in the foot-pound-second (FPS) system. Since 1 mechanical horsepower = exactly 550 ft·lbf/s, the conversion 1 ft·lbf/s = 1/550 hp is exact. Used in FPS structural and fluid dynamics: beam deflection power, pump and turbine output, and ballistic energy-transfer calculations. 19th-century American industry rated waterwheel output in ft·lbf/s before horsepower standardisation. 1 ft·lbf/s = 1.35582 W.
