Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.

The term “at least” prior to a number or series of numbers (e.g. “at least two”) is understood to include the number adjacent to the term “at least,” and all subsequent numbers or integers that could logically be included, as clear from context. When “at least” is present before a series of numbers or a range, it is understood that “at least” can modify each of the numbers in the series or range.

Aspect 23: The motor vehicle of aspect 22, wherein the container is a cylindrical or rectangular based prism, cuboid or parallelepiped and comprises one or a plurality of surfaces that define an interior volume.
Aspect 24: The motor vehicle of aspect 22, wherein the container is a rectangular based prism, cuboid or parallelepiped and comprises six surfaces defining an interior volume, wherein the two lateral surfaces are parallel sidewalls and at least one surface is movable, such that the movable surface allows access to and from the interior volume.
Aspect 25: The motor vehicle of aspect 24, wherein the movable surface is movable about at least one edge on the container, such that the movable surface moves radially downward or upward about the at least one edge.
Aspect 26: The motor vehicle of any of aspects 22 through 25, wherein the container comprises fiberglass, plastic, or metal.
Aspect 27: The motor vehicle of aspect 22, wherein the motor is cylindrically shaped and comprises an internal component, capable of rotating internally about a longitudinal axis of the motor, and wherein the first and/or second coolant lines are positioned parallel to the longitudinal axis of the motor along a line adjacent to a circumference of the motor.
Aspect 28: The motor vehicle of any of aspects 19 through 27, wherein the motor is cylindrically shaped with two oppositely facing sides, wherein the first and second coolant lines are proximate to one of the oppositely facing sides of the motor, and wherein the hydraulic pump is positioned adjacent to or substantially adjacent to the other oppositely facing sides.
Aspect 29: The motor vehicle of any of aspects 19 through 28, wherein the hydraulic pump is positioned physically adjacent to the motor but are free of operable contact.
Aspect 30: The motor vehicle of any of aspects 19 through 29, wherein the container is from about 12 inches in length, about 12 inches in width, and about 24 inches in height.
Aspect 31: The motor vehicle of any of aspects 19 through 29, wherein the container is from about 8 inches in height, width and length to about 36 inches in height, width and length.
Aspect 32: The motor vehicle of any of aspects 19 through 29, wherein the system operates at no more than about 220 degrees Fahrenheit.
Aspect 33: The motor vehicle of any of aspects 19 through 30, wherein the system operates from about 140 to about 220 degrees Fahrenheit.
Aspect 34: The motor vehicle of any of aspects 19 through 33, wherein the system further comprises an insulating material wrapping around the motor and the hydraulic pump, and wherein the insulating material comprises a sound absorption coefficient of from about 0.3 to about 1.0.
Aspect 35: The motor vehicle of any of aspects 19 through 34, wherein the system further comprises a controller operably linked to the motor and the hydraulic pump and a coolant reservoir.
Aspect 36: The motor vehicle of any of aspects 19 through 35, wherein the system further comprises an inverter in operable connection to the motor through one or a plurality of cables or wires.
Aspect 37: A method of operating the system of aspect 17 comprising:
Aspect 38: The method of aspect 37 further comprising:
Aspect 39: A method of manufacturing the system of any of aspects 1 through 18 comprising affixing the first and second coolant lines to the motor.
Aspect 40: A method of manufacturing the motor vehicle of aspect 19 comprising installing the system into the motor vehicle.
