1. A guide vane for fully reversible turbomachinery, the guide vane comprising:
a planar structure including:
an asymmetrical first edge configured to turn rotational flow exiting an impeller of the fully reversible turbomachinery into axial flow;
a symmetrical second edge opposite of the asymmetrical first edge;
an upper planar surface extending from the asymmetrical first edge to the symmetrical second edge; and
a lower planar surface opposite the upper planar surface, the lower planar surface extending from the asymmetrical first edge to the symmetrical second edge.
