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.

The invention relates to a system for the ionisation of water by electrolysis, for swimming pools, operating by means of mechanical kinetic energy of the water driven from the filtration system of a swimming pool. The invention relates to a system for the ionisation of water of swimming pools or tanks by electrolysis. Said pools or tanks must be provided with a water circulation system. The system can be easily installed in all types of swimming pool without affecting the original character thereof, and uses an autonomous and safe source of energy, the electric power being generated by the kinetic energy accumulated in the water, produced by the driving system for the filtration of the swimming pool water. This energy is used both for the generation of electricity used in the production of ions by electrolysis, and as a source for indicating operation. Kinetic energy is also used as a source of energy for the element for actuating the electrode cleaner.

A control device estimates a flow rate and an effective height difference of a fluid machine based on a characteristic detectable with regard to a rotating electrical machine and correlating with the flow rate and the effective height difference of the fluid machine. A total flow rate in a pipe system is estimated based on these values estimated by the control device and a flow resistance characteristic line, and cooperative control of the fluid machine and the flow rate control valve is performed such that the estimated value of the total flow rate becomes close to a target flow rate of the total flow rate in the pipe system.
