Abstract: A pneumatic generator cycle system includes a table, a plurality of cylinders, a carried, and a pneumatic generator. The cylinders exhaust air from the air outlet of the cylinders by weight of the carrier and the carried object, and cause the tablet to slope towards location of the carried object when the moving carried moves to the location of one of the cylinders. Simultaneously, pneumatic generator generates electricity via importing air to the air inlet of the pneumatic generator, and air flow through the outlet of the generator to the inlet of the cylinder, finally back to the cylinder exhausted the air before. The tablet is restored to balanced status due to previous process, and the tablet is raised to keep the carrier moving to the next cylinder.
