This system is a power storage device that uses off-peak electricity to raise a lead weight to the top floor of a building and store the energy. When needed, the weight is lowered to convert the potential energy into electricity, acting as a generator. The weight does not fall all at once but descends slowly over a long period of time, providing a speed reducer when necessary. The weight's gravity does not rotate the speed reducer; instead, all of it becomes a force that rotates the generator, and the weight's potential energy is not consumed by the speed reducer but is entirely converted into electrical energy. [Solution] When a piston pushes against the surface of the sand in an hourglass, the descent speed will not increase no matter how heavy the piston is. The force of the piston does not act on the sand, but all of it becomes the force that rotates the generator connected to the piston, and the potential energy lost as the piston descends is not consumed by the speed reducer but is all converted into electrical energy.
