Human to Electrical Power: Large banks of batteries captured all of this energy from the 42 bicyclists pedaling 12 hours a day for 4 days. At the end of 4 days and hundreds of Amp drinks, a meter had kept track of the total amount of energy generated. Remember, it amounted to 42 athletic bicyclists pedaling 12 hours a day for four days. That multiplies out to be equivalent to 2,016 hours of one bicyclist pedaling.

The electric meter reads 38 kilowatt-hours, which can be interpreted as 38 kilowatts for one hour (like an air conditioner running for one hour) or 1 kilowatt (like a toaster) running for 38 hours. At a cost of about 8 cents per kilowatt-hour, all of this effort produced only 3 dollars of electricity! Yes, only 3 dollars of electricity.
