  The form and application of the Lanczos potential for Bianchi spacetime are
studied. The Lanczos potential is found in some specific cases then the general
case studied. It leads to two coupled first order partial differential
equations which although they so far have not been solved in general can be
solved for many configurations. The application is to cosmic energetics: in
other words to the study of the energy of the gravitational and other fields in
the Universe.
