Claim 26:
27. A method of energy storage in a multi-weight gravity-based energy storage system for providing continuity of power input and/or output to the system without interruption or discontinuity across the full energy capacity thereof, the method comprising providing a multi-weight gravity-based energy storage system as defined in claim 1 and operating the energy storage system so as to cause the raising and lowering of successive weights according to a power input/output requirement for the system and cause the system to slow the rate of raising or lowering of a weight as it approaches an extremity of its path and start another weight moving so as to compensate for the reduction in power input/output resulting from the first weight slowing and stopping at the end of its path, whereby the input/output from the system can be provided at required power on a continuous basis for the duration of the raising or lowering of at least two successive weights.
