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 Boiler Horsepower
One boiler horsepower (BHP) ≈ 9,810 W = 33,475 BTU/h - the power to evaporate 34.5 lb of water per hour at 212°F, standardised by ASME for rating steam boilers. A small office building needs 10-50 BHP; a hospital or large plant 200-2,000 BHP. Critically, 1 BHP is ~13.1× larger than 1 mechanical horsepower (746 W) - a dangerous confusion when specifying heating equipment. 1 BHP ≈ 9,810.6 W.
