This invention relates to a new and useful improvements of an earlier scheme patented by this inventor (Canadian Patent No. 1,245,992, issued December 6, 1988) for generating electricity using gravitational energy. T he improved scheme uses a set of massive underground spinning wheels, wherein each wheel is geared to a large driving wheel requiring a lower input torque , which wheel is then fitted with a mechanism to receive and transmit gravitational torque pulses from a passing vehicle to keep the wheels in motion. The above transmission mechanism consists of a stepping board, a cylindrical rod and a movable striking head with a toothed jaw attached to the lower end of the cylindrical rod by a hinge fitted with a torsional spring. The upper end of the cylindrical rod which protrudes above the ground surface is rigidly connecte d to the moving end of the stepping board and both are kept in their initial upwa rd position by means of a "recocking" compression spring. Also, the upper jaw o f the striking head which initially remains closed and attached with the cylindric al rod due to the spring pressure, is designed to rest on a set of matching teeth. The electricity is generated by using each spinning wheel in combination with an appropriate gear system to act as the prime mover of an alternator.
