Me a bit. Lots more calcs like Ben's in the reference below about where
all these energy matters fit in the big picture more particularly for e
cars than bikes, hence my earlier posting of it on entrans site. Long
book though. Perhaps not relevant for anyone who really enjoys pushing
the pedals around. So apologies for mentioning it on this list.

Regards, Norm.

A moderately active person with a weight of 65 kg consumes food with a
chemical energy content of about 2600 "Calories" per day. A "Calorie,"
in food circles, is actually 1000 chemist's calories (1 kcal). 

2600 "Calories" per day is about 3 kWh per day. Most of this energy
eventually escapes from the body as heat, so one function of a typical
person is to act as a space heater with an output of a little over 100W,
a medium-power lightbulb. 

Put 10 people in a small cold room, and you can switch off the 1 kW
convection heater.

Thanks Ben ...
