1. A system, comprising: a pump including a manifold;a cylinder formed in the manifold;a piston disposed in the cylinder and configured to pressurize hydraulic fluid;an accumulator fluidly coupled to the piston;a hydraulic motor fluidly coupled to the accumulator; andan alternator coupled to the hydraulic motor, wherein the hydraulic motor is configured to rotate the alternator. 2. The system of claim 1, wherein the cylinder and reservoir comprise an extrusion. 3. The system of claim 1, further comprising a housing that cohouses the hydraulic motor and the alternator. 4. The system of claim 1, further comprising a hydraulic intensifier capable of receiving the hydraulic fluid from the accumulator and delivering the hydraulic fluid to the hydraulic motor. 5. The system of claim 1, wherein the hydraulic fluid comprises magnetorheological fluid (“MR fluid”). 6. The system of claim 5, wherein the MR fluid is capable of inducing an electrical current in an electrical conductor as the MR fluid travels over the electrical conductor. 7. A regenerative suspension device, comprising: a manifold;a cylinder that is coupled to the manifold and an accumulator that is coupled to the manifold, wherein the cylinder receives a piston coupled to a wheel of a vehicle, and wherein the piston transfers a pressurized fluid from the cylinder, through the manifold, and to the accumulator as the wheel of the vehicle encounters variations on a driving surface;a hydraulic motor that is coupled to the manifold and rotates in response to receiving the pressurized fluid from the accumulator; andan alternator that is coupled to the hydraulic motor and receives a rotational energy of the hydraulic motor, wherein said cylinder comprises an extrusion. 8. The regenerative suspension device of claim 7, further comprising a reservoir, wherein the reservoir and the cylinder comprise the extrusion. 9. The regenerative suspension device of claim 7, further comprising a housing that cohouses the hydraulic motor and the alternator. 10. The regenerative suspension device of claim 9, wherein the housing further cohouses the accumulator. 11. The regenerative suspension device of claim 7, further comprising a hydraulic intensifier capable of receiving the pressurized fluid from the accumulator and delivering the pressurized fluid to the hydraulic motor. 12. The regenerative suspension device of claim 7, wherein the pressurized fluid comprises magnetorheological fluid (“MR fluid”). 13. The regenerative suspension device of claim 12, wherein the MR fluid is capable of inducing an electrical current in an electrical conductor as the MR fluid travels over the electrical conductor. 14. A system for charging a power supply of a vehicle comprising: a battery, and a plurality of regenerative suspension devices, wherein each regenerative suspension device comprises:a cylinder configured to pressurize fluid upon compression by a pump within said cylinder,an accumulator functionally situated and configured to receive the fluid pressurized by said pump,a hydraulic motor, andan alternator,wherein said cylinder, said accumulator, and said hydraulic motor are coupled by a manifold,wherein said pressurized fluid rotates said hydraulic motor,wherein said hydraulic motor rotates said alternator, andwherein said alternator charges said battery. 15. The system of claim 14, further comprising a reservoir fluidly coupled to the cylinder, wherein the cylinder and the reservoir comprise an extrusion. 16. The system of claim 14, further comprising a housing that cohouses the hydraulic motor and alternator. 17. The system of claim 14, wherein the housing further cohouses the accumulator. 18. The system of claim 14, further comprising a hydraulic intensifier capable of receiving the pressurized fluid from the accumulator and delivering the pressurized fluid to the hydraulic motor. 19. The system of claim 14, wherein the fluid comprises magnetorheological fluid (“MR fluid”). 20. The system of claim 19, wherein the MR fluid is capable of inducing an electrical current in an electrical conductor as the MR fluid travels over the electrical conductor.
