1. A device for generating rotational energy for hydraulic fluids comprising:

  • at least one hydraulic cylinder, the at least one hydraulic cylinder comprising at least two chambers, wherein each of the at least two chambers are in fluid communication with the other; and

    an accumulator system comprising;

    at least two accumulators configured to receive the hydraulic fluid from the at least one hydraulic cylinder;

    a valve adapted to receive the hydraulic fluid from the at least two accumulators;

    at least one hydraulic motor adapted to receive the hydraulic fluid from the valve, wherein the hydraulic motor is configured to rotate by the displaced hydraulic fluid creating torque;

    a reservoir adapted to receive the hydraulic fluid from the at least one hydraulic motor and return the hydraulic fluid to the at least one hydraulic cylinder;

    a platform attachable to the at least one hydraulic cylinder at a first connection point and a second connection point, wherein movement of the platform from a first position to a second position causes one of the at least two chambers to displace a hydraulic fluid to the other chamber; and

    a housing having at least one axle adapted to receive at least one wheel.
