Abstract: The patented invention "System of Producing Electricity Through Water and Air Pressure" with Patent No.1-2005-000208 issued on May 12, 2009, is a vertical structure made of steel and with precise height and diameter to produce a required power output is now innovated and described as Variable On-Site Hydropower. Previously, the two cylindrical tanks (external, cylindrical water container and internal, cylindrical air pressure container) were used to contain water and air pressure to rotate a turbine which is coupled to a generator shaft to produce electricity. The two tanks are replaced with five (5) cylindrical tanks: Cistern, Water Chamber, Air Pressure Chamber, Reactor Tank and Water Recycling Tank for the same purpose. The previous Abstract stated that "The present invention concerns a system that will cause water and air pressure stored in separate cylindrical containers rotate a turbine to produce power. Combined to function interdependently, the system includes the construction of a cylindrical water container which is made of particular materials to hold and withstand the required volume of water; the cylindrical air pressure container which is also made of particular materials, is built inside the cylindrical water container to push the water upward after exiting the turbine. A water inlet on top of the cylindrical air pressure container, serves as a water intake controller from the cylindrical water container going down a diaphragm chamber. Said diaphragm chamber being connected to said water inlet at the upper end thereof and a pressurized water tank at the bottom end, stores and releases water and air pressure. The pressurized water tank, being defined by the shape of a cone, has a sediment collector pipe disposed at the bottom end of said pressurized water tank as passage for the sediments down said cylindrical water container. At the sides of said pressurized water tank are penstocks having turbines at the bottom end thereof wherein said turbines rotate and produce power as pressurized water passes through said turbines. Said power is transmitted through generator by a shaft and into a substation." The Abstract, however, of the Variable On-Site Hydropower (VOSH) will not only cause water and air pressure rotate a turbine to produce power but also has adjustable systems to be able to intensify its water and air pressure. These are contained in cylindrical Cistern, Water Chamber, Air Pressure Chamber, Reactor Tank and Water Recycling Tank to obtain a required higher power output. VOSH uses Water Recycling pipes instead of the external tank (cylindrical water container) for the purpose of water circulation from the Water Recycling Tank located at the base of VOSH structure up to the summit of the Cistern as the water receptor on top of the structure. The Water Chamber, jointly task with the pneumatic-activated valve to deliver water to the Reactor Tank is the replacement of the diaphragm chamber of the system of producing electricity through water and air pressure. The Air Pressure Chamber, which holds pressurized air, and the Reactor Tank perform as receivers of water coming from VOSH's Water Chambers. The Air Pressure Chamber and the Reactor Tank replaced the Pressurized Water Tank and the Cylindrical Air Pressure Container in the original design of the System of Producing Electricity Through Water and Air Pressure. Situated underneath the Reactor Tank's flooring are Penstocks having turbines at the bottom end, previously placed at the sides of said Pressurized Water Tank. The sediment collector pipe in the system of producing electricity through water and air pressure is replaced by sediment tank and sediment discharge duct fixed underneath the Water Recycling tank. The rationale for the innovation is to put more thrust on the descending surge of water that passes through a penstock causing the rotation of the turbine and of the generator shaft to achieve the desired revolution per minute (RPM). More thrusts on the water will result to obtaining higher power output of the generator which will be transmitted to a power substation.
