Abstract:
1. A method for producing power comprising the steps of: providing a piece of playground equipment equipped with a mechanism for compressing air from an ambient source when children set said equipment in motion; transmitting said compressed air to a storage tank via a pipeline extending from said mechanism to said storage tank; storing said compressed air within said storage tank until the air pressure within said tank reaches a pre-set level; opening an on-off valve located on said storage tank when said air pressure reaches said pre-set level; releasing said compressed air from said storage tank; passing said compressed air through a filter unit to an air motor; actuating said air motor; generating electricity from an electric generator coupled to said air motor via a gear train assembly; producing an electric current with said electric generator through cables extending from said generator to a battery; charging said battery with said electric current, wherein said charged battery provides power to operate appliances; wherein said playground equipment is a swing comprising a pneumatic rotary actuator for generating means for compressing said ambient air when said swing is swung.
