Resumen
Mechanical-hydraulic device to transform the force into electrical energy, which is specially designed to take advantage of the energy that a moving element transmits to the ground, due to its own weight, such as a vehicle when driving on the road. Characterized by being constituted from a sturdy plate, preferably of a metallic nature, intended to be located in the mouth of a ditch or transverse channel established in said road or transit area in question, through means that maintain said sheet slightly raised with respect to the general plane of the pavement and allowing a slight decrease thereof due to the effect of moving vehicles or elements on it, it being provided that said sheet incorporates on its underside and preferably in correspondence with its line longitudinal and average, a plurality of push steps that act on respective pinion is fixed to a common and longitudinal joint, duly connected, through one of its ends, to the axis of a magnet and/or alternator, so that the reciprocating movement of the sheet to the passage of the vehicles becomes a revolving movement of the cited axis, which in turn is finally converted into electrical energy supplied to an accumulator connected to the magnet and/or alternator.
