A floating reservoir for storing the same fluid as that on which it floats has a floating brim 7, flexible foldable walls 6 and a bottom equipped with floatation elements 5. As the reservoir fills the bottom is pushed down thereby maintaining a constant surface level difference between the fluid inside and outside the reservoir. Preferably the floating reservoir is part of a pumped storage system which may also have a pump, turbine-generator and a control and measurement system. The reservoir may be filled by a pump driven by a motor or a wind turbine. (Fig 4) Fluid is released from the reservoir to drive a turbine-generator to produce electricity. Preferably the floating brim is hollow and when the reservoir is in the collapsed state the foldable walls reside completely within the brim. |
