  Recent work has shown the existence of a relativistic effect present in a
single component non-equilibrium fluid, corresponding to a heat flux due to an
electric field. The treatment in that work was limited to a four-dimensional
Minkowksi space-time in which the Boltzmann equation was treated in a special
relativistic approach. The more complete framework of general relativity can be
introduced to kinetic theory in order to describe transport processes
associated to electromagnetic fields. In this context the original Kaluza's
formalism is a promising approach. The present work contains a kinetic theory
basis for Kaluza's magnetohydrodynamics and gives a novel description for the
establishment of thermodynamic forces beyond the special relativistic
description.
