From this week's lab you learned that the change in gravitational potential energy of a falling body can be captured and stored as a rotational kinetic energy of a spinning disk. This gave you the idea of a regenerative driver for an elevator in a tall building. When an elevator goes down the corresponding change in the gravitational potential energy of the elevator is transformed into the rotational kinetic energy of a solid disk-shape flywheel which can be extracted and...
