[QUOTE="Simon Bridge, post: 5479328, member: 367532"] Welcome to PF; Do you know what "efficiency" means? Where did you get the 25% figure? It is consistent with textbooks - at 20-30% being the usual range quoted. That is very efficient for an engine... though you only get that by climbing fastish: about 50 or so steps per min. (Textbook of Work Physiology: Physiological Bases of Exercise p69, 2003 by Per-Olof Åstrand et al.) [/QUOTE]
