A method to use hydraulic pressure to power a vehicle includes providing a hydraulic fluid power system having a motor in communication with a hydraulic pump; a hose in communication with the hydraulic pump, the hose having a one way valve; a gear motor in fluid communication with the hose to receive hydraulic fluid therefrom; and an alternator to receive power from the gear motor and to transfer power to a battery for storage; operating the hydraulic pump via the motor such that hydraulic fluid is pumped through the hose to the gear motor; charging the battery with power generated by the gear motor and alternator; and using the battery for one or more components of the vehicle.
