Perpetual Motion Machine [closed]
7
An engineer tests a new generator by attaching it to a motor-powered cart. The generator operates such that the cart's batteries charge when the cart's wheels turn. Assume the following true observations. Starting from a location, the cart travels Y meters in Z seconds, where Y and Z are non-zero, non-negative numbers. The engineer may power the car using one single motor, which is remote controlled. No human beings are pushing the cart or otherwise applying a force to it. The motor's battery levels are higher after the Z seconds have passed. The readings are accurate. The engineer has not altered the laws of physics and is on planet Earth. Has the engineer somehow successfully built a perpetual motion machine, or is there some other explanation?
