Query: Comment on "Logarithmic Oscillators: Ideal Hamiltonian Thermostats"
  [arXiv 1203.5968]   Campisi, Zhan, Talkner and H\"anggi have recently proposed a novel
Hamiltonian thermostat which they claim may be used both in simulations and
experiments [arXiv:1203.5968v4]. 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.
