A recently filed patent (Publication Number: US20240035451A1) outlines a method and system for storing and generating electricity using elevator cages and blocks. The method involves moving blocks between rows in an upper section and a lower section of a frame to store potential energy and generate electricity. The elevator cages, equipped with electric motor-generators, move the blocks vertically to convert potential energy into electricity. The system ensures a constant distribution of load on the frame's foundation by synchronizing the movement of elevator cages on the same or opposite sides of the frame.

The energy storage and delivery system described in the patent consist of a frame with multiple rows, elevator shafts, and elevator cages coupled to electric motor-generators. The elevator cages move blocks vertically between rows in the upper and lower sections of the frame to store and generate electricity continuously. The system includes a trolley for horizontally moving blocks towards the elevator cages and ensures synchronized movement of elevator cages to maximize energy generation. The patent also highlights the importance of maintaining a consistent load distribution on the frame's foundation for efficient operation. Overall, the method and system proposed in the patent offer a novel approach to energy storage and generation using elevator technology, potentially providing a sustainable and reliable source of electricity.
