Eremets and Troyan (Nature Mater. 10, 927-931 (2011)) claim that they produced the conducting liquid hydrogen state at 270 GPa and 295 K. Their evidence consists of disappearance of Raman signals, visual observations, and measurements of electrical conductivity in diamond anvil cells (DAC). However, there is no proof that the reported observations are due to transformations in hydrogen.
