A pumped storage electricity generating system that includes a water feed line for introducing water into a pressure vessel. Water flow valves communicate with the pressure vessel to control introduction of water into the pressure vessel. A push plate is mounted for movement in the pressure vessel. A single motor, for example, hydraulic radial piston motors, may be adapted for reciprocating the push plate linearly between a first direction wherein water is drawn into the pressure vessel through the water flow valves and a second direction wherein water is conveyed downstream through the water discharge line under pressure to the hydroelectric turbine. Other embodiments are double-acting and convey water to the turbine on each stroke.

A thermal utilization system is capable of producing power, storing energy via a chemical or and a hydropower-elevation means. It also capable of transport fluid as vapor over obstacles and terrains, as well as desalinate water. It may in some embodiments do all or some of these tasks simultaneously and with the same amount of energy. It may run with any source of energy including renewable energy sources such as solar energy, and wind. The system may use that energy to run a heat engine and, at the same time, stores that energy via chemical separation. When energy is needed, the system may withdraw the chemical substances and lets them interact to claim the energy back, and then use it to run a heat engine and desalinate water. Some parts of the system can be used for cooling and heating. The system may be configured to be an air conditioner unit or a refrigerator that has an internal back up energy storage.

A sluice gate for a hydropower station, a method of operating a sluice gate and a hydropower station. The sluice gate includes rollers via which the sluice gate can be movably mounted on rails and a sealing surface having a seal with which an upstream water can be sealed off from a downstream water. Lubricant lines are provided through which lubricant can be fed to the rollers and lubricant return lines are connected to the rollers. Via the lubricant return lines, used lubricant can be guided from the rollers to one or more collection locations in order to be able to collect and properly dispose of used lubricant.
