Abstract: An airflow power station preferably comprises a windmill engine rotatable by wind including a main shaft and a rotational speed sensor, a compressed-air tank, a compressor charging the tank, an electric generator, a flywheel conveying rotation to the compressor and to the generator, and two pneumo-cylinders with pistons and sensors sensing their initial and ending positions. Each piston is coupled with a rod hingedly associated with a clutch controllably engaging and disengaging the piston with the flywheel. Each pneumo-cylinder is divided into an inner and an outer chamber, pneumatically communicating with the tank via an intake valve controllably supplying compressed air and a pneumo-regulator controllably switching the airflow ‘on’ and ‘off’ depending on the rotational speed of main shaft. Each pneumo-cylinder includes a reverse spring disposed in the inner chamber thereof, compressed during a work stroke of the piston and released upon return of the piston into its initial position.
