1. A system for generating electricity comprising
at least one structure defining an upper support surface and a lower support surface;
a plurality of cranes adapted to move a plurality of bodies from the upper support surface to the lower support surface, and vice versa;
wherein each crane is provided with
a hook adapted to grasp a body of said plurality of bodies;
and a motor/generator connected to the hook, adapted to transform into electricity the kinetic energy of a body grasped by the hook, which moves, in particular substantially vertically, under the effect of gravity towards the lower support surface;
wherein said motor/generator is adapted to act as a motor to move a body grasped by the hook upwards;
wherein each crane is provided with
a guide, or bridge, which extends above the upper support surface and above the lower support surface;
and a carriage constrained to the guide; the carriage being adapted to slide along the guide;
wherein the hook is constrained to the carriage;
wherein the guide, or bridge, is adapted to guide the movement of the carriage parallel to an axis (X), which is perpendicular to a horizontal axis (Z), the axis (X) and the horizontal axis (Z) being perpendicular to a vertical axis (Y);
wherein each crane is provided with a first motor to move the carriage and the hook along said guide from the upper support surface to the lower support surface, and vice versa;
wherein for each crane a second motor is provided to move the respective crane along the horizontal axis (Z), so as to move the hook above the upper support surface;
wherein at least one rail is provided;
and wherein each crane is constrained to said at least one rail and is adapted to slide with respect thereto by means of said second motor to move the hook above the upper support surface.
