FIELD OF THE INVENTION [0001] This invention is in the field of electric power generating systems that use compressed gas and, more particularly, to systems using a rotary gravity compressor to compress air. BACKGROUND OF THE INVENTION [0002] Electrical power is generated by a number of different processes throughout the United States and the world. For example, coal, natural gas or oil can be burned, or nuclear power can be used, to generate steam to drive a steam turbine to drive an electrical generator to produce electricity. These types of plants are well known, and vary in design details, but they all involve the use of a depletable fuel and raise environmental concerns because of byproducts that such plants generate that pollute the environment. [0003] Because of concerns over depletion of natural resources, as well as environmental concerns, efforts have been made to generate electricity through cleaner (or "greener") processes using alternative power sources or power generating schemes that do not deplete limited natural resources or create harmful byproducts. For example, efforts have been made to generate electricity through solar and wind power and hydroelectric power has been used for some time when conditions are right for its use. [0004] Other efforts have been directed to ways that power can be generated during off-peak times and stored for use during peak demand conditions, thus minimizing the need for new power plants and increased capital spending. [0005] As energy consumption increases throughout the world, especially with developing countries like China consuming more and more energy, and with concerns about pollution and limited natural resources becoming more and more of a concern, there is a need for new and improved methods of generating electrical power that do not deplete limited natural resources, that do not pollute or at least are more environmentally friendly, and that are still economical. It is this need to which the present invention is directed. SUMMARY OF THE INVENTION [0006] The present invention is generally directed to a rotary gravity compressor with a rotating shaft held between two support walls that is driven by a drive gear mechanism (which may be a hydraulic system). Multiple cylinders are affixed to and juxtaposed about the rotating shaft at different angles relative to rotation of the shaft. Each of the cylinders has two bases at its opposite ends, each of which has an intake valve and an outtake valve for controlling flow of gas into and out of the cylinder, respectively, and the outtake valves are connected to an air outtake pipe with multiple air connections. A piston is movable within each cylinder between the two bases as a result of gravity due to rotation of the shaft and movement of the piston in a downward direction creates compressed air within the cylinder which is released from the cylinder through a bottom outtake valve when the piston has reached full compression while uncompressed air is introduced into the cylinder through a top intake valve as the piston moves toward the bottom base. [0007] In a first, separate group of aspects of the present invention, bearings are located on the pistons to lessen friction, a compression seal is used to assist in compression of gas as the piston moves downwardly, shock absorbing devices are used to lessen shock as the piston reaches maximum compression and locking devices are used to hold the piston in place until it is released. [0008] In a second, separate group of aspects of the present invention, a rotary gravity compressor is used in a system or method for generating power in which compressed air from the air outtake pipe is used to generate work or power an air turbine or a generator or is stored in an air tank that is then used to power an air turbine or a generator or a pneumatic tool. [0009] Accordingly, it is a primary object of the present invention to provide improved compressed air power generating systems using a rotary gravity compressor. [0010] This and further objects and advantages will be apparent to those skilled in the art in connection with the drawings and the detailed description of the invention set forth below.
