Abstract: An apparatus and method for increasing energy harnessed from a liquid body flowing through a conduit includes a conduit having ascending, connecting and descending sections, valves inside the conduit, a fill unit, and at least one turbine. The valves, located in the ascending and descending portions of the conduit, regulate the flow of the liquid body through the conduit. The fill unit includes at least one of a pump and a siphon for replenishing liquid in the conduit and initiating a constant flow. An optional removably attached extension to the conduit increases the hydraulic head and increases the flow of the liquid body. The extension may include additional turbines. The turbines harness energy from the liquid body flowing with an increased flow rate through the conduit. The harnessed energy is increased by utilizing the atmospheric pressure exerted on the liquid body resulting in an increased constant flow through the conduit.
