Embodiments described herein include a method for converting free-piston linear motion to rotary motion, comprising: providing a free-piston generator or motor/generator that has at least one piston having two compression heads; and, for each piston, a surface is provided on each compression head defining a helical channel, wherein the piston is rotated in a single direction due to the force imparted to the piston as compressed air in an air box is forced through the helical channel.
