1. An electricity generation system for generating electrical energy from potential energy, the system comprising:

  • a support frame having a base and an upper portion;

    an actuator for pumping hydraulic fluid therethrough, the actuator comprising;

    an elongate cylinder having upper and lower ends and a hollow interior chamber open on the upper end and closed on the lower end, the lower end being mounted on the base; and

    an elongate piston rod extending outwardly from the upper end and being sized and configured complimentary to and axially slidable within the interior chamber between a first level and a second level;

    a counterweight of a predetermined mass attached to the piston rod above the upper end;

    a hydraulic assembly mounted on the base for circulating the hydraulic fluid therethrough, the hydraulic assembly comprising;

    an accumulator fluidly connected to the lower end and being configured to receive the hydraulic fluid therefrom and release the hydraulic fluid at a prescribed pressure level;

    a hydraulic turbine fluidly connected to the accumulator and being configured to receive the pressurized hydraulic fluid therefrom such that the hydraulic turbine may be rotated; and

    a generator mechanically connected to and rotatably driven by the hydraulic turbine and being configured to convert rotational motion into electricity;

    a multiple pulley system configured for moving the counterweight towards the upper portion, the multiple pulley system comprising;

    a pair of support frame pulleys rotatably mounted on the upper portion;

    a pair of counterweight pulleys rotatably mounted on the counterweight; and

    a coupling line having first and second ends, the first end being connected to the upper portion, the coupling line being reeved through the counterweight pulleys and the support frame pulleys; and

    an elevating motor mounted on the support frame and connected to the second end, the elevating motor being configured to alternately raise and lower the counterweight between the first and second levels by intermittently winding up and paying out the coupling line to reciprocate the piston rod within the interior chamber such that the hydraulic fluid may be circulated through the hydraulic assembly.
