Abstract:

Provided is an energy storage system configured to accumulate energy for subsequent discharge. 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).

Abstract:

Provided is a method for developing a software product. The method can be implemented by stakeholders or by a service. Further, software can implement the method to provide project metrics before and during the development of the software product. The method identifies elements of the software product for development that have associated economic values for multiple time periods. The multiple time periods indicate the time to develop and then implement the software product. The elements can have dependencies that require the development of the elements as strands. Consequently, the strands also have economic values that are adjusted to permit the identification of the elements of the software product to develop.
