1. A system for electricity generation from a plurality of wheeled vehicles moving along a road, the system comprising:

  • a flap, hingedly connected at a first end at a road level to a frame, and having two states;

    (i) a protruding state, in which the flap is inclined upwards and a second end of the flap is above road level, and (ii) a level state, in which the flap is on a level with the road, wherein the flap is arranged to be moved from the protruding state to the level state by vehicles moving across the flap and pushing down the second end of the flap,a rack and a pinion, the rack being vertical and jointedly connected by a bar to the second end of the flap, and the pinion being mounted on an input axis and arranged to turn upon vertical movement of the rack due to the vertical pushing down of the second end of the flap by passing vehicles,a transmission connected to the input axis and arranged to transmit only rotations thereof due to downward movements of the rack to an output axis, and de-couple the input axis from the output axis upon rotations of the former resulting from upward movements of the rack, to accumulate rotations in one direction, and a flywheel connected to the output axis and arranged to receive the transmitted rotations from the transmission, and operate an alternator over a belt to produce electricity from the accumulated rotation of the flywheel.
