Patent ID: 8561747

Claim:
An electrical generating power plant, comprising: at least one DC power source for generating direct current (DC); a DC/AC converter for converting the DC to alternating current (AC) and outputting a portion of the AC via a power plant output port to supply an AC load; an array of electrical storage cells electrically connected to said at least one DC power source, and output stored DC power to the DC/AC converter under certain conditions; a supply of compressed nitrogen gas; gas compressor connected to and powered by the DC/AC converter for compressing said nitrogen gas to a high pressure, non-liquid state; high pressure tanks connected by a high pressure conduit to the compressor for receiving the high pressure nitrogen gas in the high pressure, non-liquid state; a rotary pneumatic motor (RPM) connected to the compressor and high pressure tanks via the high pressure conduit; an alternator/generator mechanically connected to the RPM by a drive shaft in order to generate AC when the RPM is driven by said high pressure nitrogen gas; and low pressure tanks in fluid communication with the RPM at one end via a low pressure conduit, and in fluid communication to the compressor at its other end via a low pressure conduit forming a closed loop for compression/decompression of the nitrogen gas as an energy carrier to drive the RPM to generate and output AC by the alternator generator, provided to an output port of the plant.
