A rotational power system (RPS) that utilizes environmental air to produce continuous rotation of a circular object such as a tire or wheel. The RPS has an air intake assembly having at least one air intake member. The intake member has an outer side edge with at least one opening into which an air intake valve is inserted, with a valve plunger extending outward from the valve. The intake member also has two side surfaces with a second side surface having an opening, and an internal cavity within which an air intake interface is located. Proximate to the air intake member is an air intake extension member having an opening, a cover with an air outlet bore, a side member with perimeter teeth, a connecting rod, and a circular structure onto which the intake assembly and the at least one intake member are attached. Connected via an air hose to the intake member is an air tank, and an air heater is connected to and receives air from the air tank. A turbine has an outer edge with concave members, an inner frame, a center opening and an axle extending through the center opening and attached to a first wheel located adjacent to the turbine. As a tire and wheel rolls on the ground surface, the tire and wheel interfaces with the extending valve plungers forcing each plunger down and causing air to enter via the air intake member and then directed through the air tank and air heater, the heated air is directed to the turbine thereby causing the turbine to rotate about the axle and the heated air to be directed back to the tire and wheel causing the tire and wheel to rotate.

A vehicle structure with unitary casing for an attritable gas turbine engine comprising a vehicle structure forming a unitary casing having a casing wall opposite the vehicle structure; a bypass duct formed between the casing wall and the vehicle structure, wherein the unitary casing is configured to receive a core of the attritable gas turbine engine.

A tractor-trailer is disclosed, with associated apparatuses. A tractor may include a tractor air duct disposed underneath a cab. The tractor air duct may extend between a front opening at a front of the tractor and a rear opening at a rear of the tractor. A trailer may include a duct system that receives airflow from the rear opening of the tractor air duct and directs the airflow to a location behind a cargo compartment. An air distributor may be disposed behind the cargo compartment. An air distributor may include a fairing with openings, so that airflow from the duct system enters a space between the cargo compartment and the fairing, and exits the openings behind the trailer.

A mechanical power system provides torque without using a heat engine where fossil-fuel engines have conventionally been used, by replacing the fossil-fuel burning engine with a rotary pneumatic motor and feeding pressure-regulated compressed gas to the rotary pneumatic motor. The rotary pneumatic motor can be used anywhere, and requires preferably compressed nitrogen in a non-liquid state. Automotive, marine and electrical generating applications are adaptable, and auxiliary power is available for emergencies where a supply of compressed gas has been exhausted. A screw-type compressor can be electrically powered to supply compressed gas to the pneumatic motor where tanks of compressed gas have been exhausted. An electrical generating power plant includes an array of solar panels for generating direct current (DC) and a DC/AC converter for converting the DC to alternating current (AC) and outputting a portion of the AC via a power plant output port to supply an AC load.
