Abstract: A rotor system comprising at least a rotor adapted to rotate with respect to a stator, the rotor system further comprising a densifier adapted to densify gas of an upstream volume by an average density rise of at least about 1%, wherein the cross-section area of the volume is the rotor sweeping area and the depth of the volume is at least about one millimeter.
