We present a mini-review of some of the most “spectacular” effects appearing in the dynamics of granular gases where the dissipative nature of the collisions leads to a rich phenomenology, exhibiting striking differences with equilibrium gases. Among these differences, the focus will be on the illustrative examples of “Maxwell Demon”-like experiment, modification of Fourier’s law, non-equipartition of energy and non-Gaussianity of the velocity distributions.
