Abstract
The present invention provides a variable mass elevator apparatus and method of operation, wherein the apparatus comprises an electronic scale, an elevator car, a traction sheave, a control computer, a mass storage area, a mass, a mass conveyor, a floor control panel outside of the elevator. When a passenger desires to operate the elevator, the passenger steps on the electronic scale and chooses a floor on the floor control panel, wherein the floor control panel has buttons for each floor. The electronic scale relays the weight of the passenger to the control computer, and the floor control panel relays the desired floor to the control computer. The control computer instructs a mass conveyer to couple a mass corresponding to the weight of the passenger to the elevator cable to act as a counterweight and equalize the potential energy of the elevator according to the desired floor of the passenger and the weight of the passenger.
