Systems and devices for storing mechanical energy in a spring motor or the like are described. In one implementation, an energy storage device includes an elastic rope, a spool and a control mechanism. The elastic rope is reversibly deformable from a relaxed state to a stretched state for storing mechanical energy. The spool is coupled to the elastic rope, and is configured to maintain the elastic rope in the stretched state while the elastic rope is wound around the spool. The control mechanism is coupled to the spool and is configured to allow the spool to rotate in response to the elastic rope relaxing from the stretched state to the relaxed state for retrieval of stored mechanical energy. In some implementations, the elastic rope may be formed from an elastomer wrapped with a fiber made from carbon nanotubes or other synthetic strengthening material. |
