NOVELTY - The system (10) has a turbine (40) connected to a reservoir (20) by a tube (50), and another tube (60) connecting the turbine to another reservoir (30). A pump (80) pumps water from the latter reservoir to the former reservoir. A solar panel provides electric energy to the pump. The electric energy from the solar panel powers the pump to pump fluid e.g. water (100), from the latter reservoir to the former reservoir, such that the fluid travels through the former tube into and through the turbine to generate electricity, where the fluid is cycled repeatedly through the reservoirs.    USE - Electricity generating system for being attached to an electrical system in a building (claimed) using an economic and environmental-friendly energy source and gravity via a hydroelectric power plant for generating electricity. Can also be used in a hill, a mountain, or an architectural center piece.    ADVANTAGE - The system allows for consistent, uniform power to be provided as the system can take over to provide energy when an energy source fails. The system includes a sensor that senses when additional electricity is needed. The system can serve as a supplemental energy source which is only turned on occasionally, so that there is less strain on the primary energy source and on the environment. The system can be scaled to produce varying amounts of electricity depending on the size of the pipes or tubes, which may comprise penstock, and the speed of the water. The speed and the power of the water is greatly increased as the opening in the first reservoir is about times the size of the opening in the turbine, so that the turbine is rotated faster, thus producing more electricity.    DETAILED DESCRIPTION - The system has a generator coupled to the turbine.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic block diagram of an apparatus for generating electricity.
