Abstract: 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.
