  M.W.Evans tried to relate the electromagnetic field strength to the torsion
of a Riemann-Cartan spacetime. We show that this ansatz is untenable for at
least two reasons: (i) Geometry: Torsion is related to the (external)
translation group and cannot be linked to an internal group, like the U(1)
group of electrodynamics. (ii) Electrodynamics: The electromagnetic field
strength as a 2-form carries 6 independent components, whereas Evans'
electromagnetic construct F^\a is a vector-valued 2-form with 24 independent
components. This doesn't match. One of these reasons is already enough to
disprove the ansatz of Evans.
