Dynamical nonlinear systems provide a new approach to the old problem of increasing the efficiency of thermoelectric machines. Here we discuss stylized models of classical dynamics, including non interacting complex molecules in an ergodic billiard, a disordered hardpoint gas and systems with broken time-reversal symmetry where the Curzon-Ahlborn limit for efficiency at maximum power can be overcome . The main focus will be on the physical mechanisms, unveiled by these dynamical models, which lead to high thermoelectricefficiency approaching the Carnot limit.
