Abstract: genetic energy from the irregularities of road shock forces usually absorbed by the Automotive Shock Absorber, in a moving auto powered vehicle is recovered and conververed usable to D.C.  Power.   The "D.C. POWER GENERATING AUTOMOTIVE SHOCK ABSORBER" adds new functuality to present day automotive shock absorbers:     1. It has the improved ability to generate D.C. Power using the the "up and down "action of the shock when the autobile is mobile.     2. With the "D.C. POWER GENERATING AUTOMOTIVE SHOCK ABSORBER" all components for operatiion including the generator are contained within the invention.     3. The "D.C. POWER GENERATING AUTOMOTIVE SHOCK ABSORBER" fits the same size and profile of the existing art. This enables "D.C. POWER GENERATING AUTOMOTIVE SHOCK  ABSORBER" to bolt on-to vehicles and generate power D.C. Current for lights, radio, charging the battery as well as charging external devices such as cell phones, etc. in cars, trucks, RV's, motorcycles, scooters and bicycles.     4. The "D.C. POWER GENERATING AUTOMOTIVE SHOCK ABSORBER" can be bolted on-to older vehicles right on through to the latest electric and hybred automobiles. This means the "D.C. POWER GENERATING  AUTOMOTIVE SHOCK ABSORBER" has no barriers in terms of being introduced and installed into vehicles and the the market place.     In a motor vehicle, a shock absorber is used to dampen the forces of the road shocks, and to control the vehicles load from bouncing dramatically. The energy absorbed is normally displaced in the form of heat into the surrounding. The kinetic energy of the sudden vertical movement is mostly absorbed by the coil spring which provides most of the work. To absorb the shock force. The shock absorber mates with the spring to provide resistance to the shock force, and to prevent the vehicle body from suddenly bouncing back. When the shock is absorbed, the coil spring expands back slowly while being retained and controlled by the mating shock absorber, The absorber fluids bleeds through a number of orifices at a desired flow rate to provide controlled resisting force against the expansion force. The present invention replaces the working fluids (though it must be lubricated) by means of a calibrated double helical drive screw which works in harmony with a calibrated coil spring. The estimated electric power generated by the invented system shall vary depending on the road conditions, driving speed, vehicle load, driving style ... etc, the electric power generated can be used to drive electrical components of the vehicle that normally consumes energy from the electric, gasoline, or diesel fueled engine. The radiator fan, the electric lighting system and many other electric and electronic devices, accessories and controls may be operated by the electric energy generated by the system. In the case of of an electric driven vehicle, the power generated by the invention can be used to reduce the draw down rate of the electric battery, thus increasing the cruising distance of the vehicle while still using the same initial battery charge.
