Question

A person in good physical condition can put out 100 W of useful power for several hours at a stretch, perhaps by pedaling a mechanism that drives an electric generator. Neglecting any problems of generator efficiency and practical considerations such as resting time:

(a) How many people would it take to run a 2.00 kW electric clothes dryer?

b) How many people would it take to replace a large electric power plant that generates 700 MW?
