| 摘要 |
This invention relates to a mechanical energy storage system, incorporating upper and lower reservoirs supported in a rigid frame. Metal balls are initially stored in the upper reservoir, a form of storage with potential energy that can be converted to kinetic energy. The balls are selectively released from the upper reservoir. The balls are then guided by a plurality of ramps, and said balls are then deposited in the lower reservoir. The invention further relates to renewable energy, such as solar energy, as a means of returning the balls from the lower to the upper reservoir. A further object is that the invention will continue to operate during those periods of time when solar energy is unavailable, without relying on backup power from battery packs or from power coming directly from a utility company.
