Gas driven motor

A gas driven motor comprising:

• a housing defining a circulation chamber and a shutter chamber, wherein the housing includes an intake port and an exhaust port;
• a drive axle positioned along a pair of parallel circulation chamber walls and rotatably attached thereto, wherein the drive axle is perpendicular to the pair of parallel circulation chamber walls;
• a vane having an attached edge, a leading edge parallel with and opposite to the attached edge, and a pair of vane side edges, wherein
• the pair of side edges are parallel with respect to one another and form a matching curve with respect to one another, wherein
• the vane includes a curved surface defined by the pair of side edges, wherein
• the vane is mechanically coupled with the drive axle along the attached edge, and wherein
• the vane is configured to rotate through the circulation chamber along an axis of rotation in response to an application of a gas flow;
• and
• a shutter having a sealing edge, a pivoting edge parallel with and opposite to the sealing edge and a pair of shutter side edges, wherein
• the shutter is positioned along a pair of parallel shutter chamber walls and pivotally attached thereto, wherein
• the shutter pivotally extends into the circulation chamber in a first position, and wherein,
• the shutter pivotally retracts into the shutter chamber in a second position.
