A rotary vane/expansion device having a housing, a rotor with a shaft having an axis, a plurality of telescoping vanes extending radially outwardly from the axis to rotationally contact the inner wall of the housing. There is a movable housing which rests on a track. There are two sets of drive pistons. One drives the piston (and housing) in one direction which is in a plane perpendicular to the axis of the shaft. The second drive piston drives the housing along the track in the opposite direction so that the amount of compression can be controlled. The outer edges of the vanes are provided with pin rollers to reduce wear. Telescoping vanes are also disclosed. The cross-section of the housing in a plane perpendicular to the axis has an ovoidal shape. This can also be used to obtain fresh water from salt water. Salt water is placed in a tank with heating coils in it. The tank has an overhead dome with a trough to catch condensed water. The hot compressed air is passed through the heating conduit to heat the water, causing steam to rise in a dome covering the tank. The air is passed back through the expander side, and the expanded cool air flows through the cooling panel in the dome to condense the steam, which is collected in a trough.
