Abstract
Abstract A generator is driven by a miniature hydraulic turbine which, in turn, is driven by water flowing to, through or from the water system of a residential or commercial building. Electricity generated by the generator is stored in storage batteries for emergency or supplemental use. A distribution panel is operable to give a readout of the amount of stored electricity. The readout can be obtained by pushing a button on the distribution panel and such readout directly and immediately informs the reader of the number of hours a specific appliance can be operated by the stored electricity.
