摘要： Dams are a useful source of energy. An embodiment of a dam according to the present invention includes precast segments configured to be coupled together to form a dam optionally used to generate energy. An embodiment includes encasing an existing dam structure using interconnected precast segments. An underpinning system may penetrate the existing dam structure and be employed to assist in maintaining position of the dam or segmental components. A further embodiment includes encasing a main energy generation component using interconnected precast segments formed from a composite material including electrically conducting fibers, an electric circuit configured to measure and report the electrical resistance using a transmitter or transceiver to a dam stress/strain monitoring server. The electrical circuit may be powered directly or indirectly by available power supplied by the main energy generation component.

摘要： A water reservoir system for generating, accumulating, storing, and releasing electrical energy comprises a reservoir wall built in a shallow body of water such as a sea or an ocean with a height exceeding the outside water level by about 10-25 m, thereby defining an interior of the water reservoir. Excess electrical energy from other renewable sources of electricity such as wind, solar power, or supplied by a local power grid is used to operate water pumps to fill the interior of the water reservoir with water during times of peak supply of electricity. Water is drained from the water reservoir to the outside body of water and generates electrical energy by flowing over a plurality of water turbines, thereby generating electricity and supplementing electrical power for the local power grid during times of high demand. Additional interior sources of renewable energy may be used to supplement external sources of electrical power in operating the system of the invention.
