1. A gas compressor, comprising:
a cylindrical drum having a first end and a second end opposite the first end, the second end affixed to a shaft configured to rotate the drum, the drum including a compression channel assembly configured to rotate with the drum and defining a plurality of compression channels, each compression channel extending outwardly from an opening at a centralized common pressure zone toward an area adjacent an interior surface of the drum; and
a return assembly configured not to rotate with the drum and having at least one liquid inlet, a fluid outlet, a gas inlet and tubing connecting the liquid inlet and the gas inlet to the fluid outlet, the at least one liquid inlet extending into an annular lake formed within the drum when the drum is rotated and configured to draw liquid from the annular lake, the tubing configured to channel the liquid toward the gas inlet where the liquid is mixed with incoming gas and channeled to the fluid outlet;
wherein fluid entering the centralized common pressure zone is forced into the opening of each compression channel, wherein gas in the fluid within each compression channel is compressed as it travels from the centralized common pressure zone toward the area adjacent the interior surface, wherein at least some of the pressurized gas is separated from the liquid in the fluid prior to leaving the compression channel assembly, and wherein the liquid is returned to the annular lake.
