Abstract
We show that for a two-dimensional gas of elastically interacting particles the thermoelectric efficiency reaches the Carnot efficiency in the thermodynamic limit. Numerical simulations, by means of the multi-particle collision dynamics method, show that this result is robust under perturbations. That is, the thermoelectric figure of merit remains large when momentum conservation is broken by weak noise.
