Abstract: A method for generating electrical energy through the fall of a weight upon a hydraulic fluid (reference sign H) is characterised in that it employs the kinetic energy of a weight (11) which is accelerated by the force of gravity when falling inside a tube (12) which contains a hydraulic fluid which is expelled through a discharge pipe (14) to a gravity box (22) in which blades (21) are contained to rotate a shaft (20) which transfers mechanical energy to an elastic coupling (19) which absorbs shocks and transmits a stable rotation to the alternator (17) which generates electrical energy for the electrical grid and to recharge a battery (10) by cables (18) which also power the motor.
