CaptainPanic Posted March 29, 2011 Share Posted March 29, 2011 (edited) You probably want power, not energy? 100-400 W http://en.wikipedia.org/wiki/Human-powered_transport#Available_muscle_power http://hypertextbook.com/facts/2003/WeiLiangMok.shtml http://www.alternative-energy-news.info/pedal-a-watt-stationary-bicycle-generator/ Edited March 29, 2011 by CaptainPanic Link to comment Share on other sites More sharing options...
swansont Posted March 29, 2011 Share Posted March 29, 2011 Are you asking for energy the body produces or the mechanical work being done? i.e. are you looking at what you can do with the energy, or how many Calories the person is burning? Because no heat engine is 100% efficient. The range of values CaptainPanic cites are for mechanical work; the thermal output will be around 4 times higher.

TonyMcC Posted March 29, 2011 Share Posted March 29, 2011 An electrically assisted bicycle uses a 200W motor which has no difficulty in maintaining 15 mph along the flat. This falls nicely within the limits given by CaptainPanic. Link to comment Share on other sites More sharing options...

That's an important point since a 200W electric bicycle doesn't come with an 800W heater but a pedal-powered bicycle does. Link to comment Share on other sites More sharing options...
