We show, however, that this is not possible due to the length and time scales involved, which depend exponentially on the total energy of the system. The implementation suggested by Campisi et alii implies equilibration times greater than the age of the universe for systems with more than a few dozen particles.","authors_text":"Marc Mel\\'endez, Pep Espa\\~nol, William G.
