We point out that partcile spectra with power-law tail lead to an increased energy and entropy per particle. This way even a massless plasma may give E/N = 1 GeV at T = 175 MeV temperature, alike thermal hadronic fits to RHIC experiment. In this case E/NT = 6 instead of 3.LaTeX, revtex4, prc, 16 pagesHigh Energy Physics - Phenomenologytext
