QUESTION:

Your Own humans generating electricity by pedaling a device similar to a stationary bicycle. Construct a problem in which you determine the number of people it would take to replace a large electrical generation facility. Among the things to consider are the power output that is reasonable using the legs, rest time, and the need for electricity 24 hours per day. Discuss the practical implications of your results.

QUESTION:

Your Own humans generating electricity by pedaling a device similar to a stationary bicycle. Construct a problem in which you determine the number of people it would take to replace a large electrical generation facility. Among the things to consider are the power output that is reasonable using the legs, rest time, and the need for electricity 24 hours per day. Discuss the practical implications of your results.

ANSWER:

Step-by-step solution Step 1 of 4 Suppose a group of people are pedaling a device similar to a stationary bicycle which can generate electricity. Assuming that they are pedaling at 13-18 km/h for 20 hours a day (4 hours of resting period is given per day), the energy generated by them will be: Here P is the power output of each person and x is the number of people in the group.
