Plant for recovering energy from fluids, comprising, mutually connected in cascade: - a fluid reserve at the lowest level in the plant; - an exchange chamber placed upwards with respect to the fluid reserve, with reference to the ground, and downstream of the fluid reserve with respect to the fluid flow direction, said exchange chamber for changing a direction of fluid entering the chamber from bottom to top and exiting the chamber from top to bottom; - a fluid compensating reserve for compensating the amount of fluid to be supplied to a fluid exchange pump placed downstream; - a fluid compensating chamber placed downstream of the pump in which, when the dynamic fluid acceleration process is triggered, the gas contained in the upper part of the chamber, which exceeds the fluid level, is compressed or decompressed in such a way as to allow the pump to freely exhaust and that the fluid flow is free in its fall and can benefit from gravity and acceleration induced by the pump; - a backup gas chamber connected to the fluid compensating chamber and used as gas reserve to perform a release of fluid under free fall from the fluid compensating chamber; and - a turbine connected to and placed downstream of the fluid compensating chamber and connected to and placed upstream of the fluid reserve all the above components (1, 7, 10, 12, 14, 17, 26) mutually connected in a closed circuit, so that a fluid flow comes to the turbine when falling with a positive thrust composed of the sum of the forces generated in the various steps of the path followed by the fluid, characterized in that said fluid compensating chamber is used as pressure exchange point, volume, density between fluid going out of the pump through an accompanying cone and fluid coming from the backup gas chamber to start the resulting fluid through a collector to a duct which supplies it to the turbine. - a fluid reserve at the lowest level in the plant; - an exchange chamber placed upwards with respect to the fluid reserve, with reference to the ground, and downstream of the fluid reserve with respect to the fluid flow direction, said exchange chamber for changing a direction of fluid entering the chamber from bottom to top and exiting the chamber from top to bottom; - a fluid compensating reserve for compensating the amount of fluid to be supplied to a fluid exchange pump placed downstream; - a fluid compensating chamber placed downstream of the pump in which, when the dynamic fluid acceleration process is triggered, the gas contained in the upper part of the chamber, which exceeds the fluid level, is compressed or decompressed in such a way as to allow the pump to freely exhaust and that the fluid flow is free in its fall and can benefit from gravity and acceleration induced by the pump; - a backup gas chamber connected to the fluid compensating chamber and used as gas reserve to perform a release of fluid under free fall from the fluid compensating chamber; and - a turbine connected to and placed downstream of the fluid compensating chamber and connected to and placed upstream of the fluid reserve all the above components (1, 7, 10, 12, 14, 17, 26) mutually connected in a closed circuit, so that a fluid flow comes to the turbine when falling with a positive thrust composed of the sum of the forces generated in the various steps of the path followed by the fluid, characterized in that said fluid compensating chamber is used as pressure exchange point, volume, density between fluid going out of the pump through an accompanying cone and fluid coming from the backup gas chamber to start the resulting fluid through a collector to a duct which supplies it to the turbine.
