For his science fair project, John decided to experiment with renewable energy sources. He hoped that his work will solve all of our energy problems. He decided to power a generator with an electric motor. He thought once the generator was up to speed, he could just flip a switch and the generator could supply the electricity that powered the electric motor. John was for sure he made a historical discovery, he found an alternative to fossil fuels. His energy source was purely renewable. Why did his experiment fail once he put it to the test?

If the whole apparatus made audible sounds, it would also lose energy to that.
