1. An apparatus for generating energy by utilizing the weight of vehicles moving on a predetermined surface, comprising:

  • one or more bladders containing a fluid;

    a one-way intake value coupled to said bladder for allowing one-way intake of a working fluid into said bladder;

    a one-way exhaust valve coupled to said bladder for allowing one-way exhaust of said working fluid from said bladder;

    a pair of vertically movable, parallel pressure plates comprising an upper plate and a lower plate with said bladder fitted therebetween;

    a pair of treadle plates operably interconnected with said predetermined surface, coupled together hingedly at a hinged point defining a position elevated above said predetermined surface;

    a vertical shaft capable of vertical movement, being pivotally connected to said hinged point of said treadle plates at the uppermost point of said shaft;

    a plurality of connecting links being pivotally connected to said vertical shaft, and which are pivotally fitted to lower levers operably mounted on lower fulcrums, with said lower levers pivotally connected by lower connecting arms with said lower plate;

    a plurality of arms which are pivotally fitted to said connecting links at the lowest portions of said arms and which are pivotally fitted to upper levers at the uppermost portions of said arms, said upper levers being operably mounted on upper fulcrums and pivotally connected to said upper plate by means of a plurality of upper connecting arms;

    compressible spring means fitted to the base of said vertical shaft for slightly resisting downward vertical movement;

    means for storing pressurized working fluid received from said bladder; and

    means for converting at least a portion of said pressurized working fluid into mechanical or electrical energy.
