One embodiment includes an indirect energy storage assembly configured to accept energy input from a direct storage assembly. The indirect energy storage assembly includes a converter for lifting a mass, a speed reducer coupled to the converter for increasing torque provided, and a mass coupled to the speed reducer for generating potential energy when raised. In one embodiment, the direct energy storage assembly produces energy based on descent of a mass, the descent controlled by operation of a speed increaser coupled to a generator. In one example, the speed increaser provides an input:output ratio of at least 1:100. The speed increaser can be configured based on parameters of the generator (e.g., speed and torque).
