The dynamics of interacting Brownian particles can be described by a stochastic equation for the density field. I will show how the linearised version of this equation can be used to recover, very simply, certain of Onsager’s results on electrolyte conductivity. In addition I will show how it can analyze the out of equilibrium thermal Casimir effect between parallel plates containing Brownian charges, in particular the case where the plates are held at different temperatures and when an electric field drives a current in one of the plates.
