Last year, physicists at the University of Rochester demonstrated room temperature superconductivity in a sample of carbonaceous hydrogen sulfide at about 15 degrees Centigrade.
But there was also a problem: the demonstration took place at huge pressures — 267 gigapascals, about two thirds of the pressure at the center of the Earth. The researchers achieved this in tiny quantities of material inside a diamond anvil that crushed its contents with mind-boggling forces. These forces allow new exotic lattice structures to from and in some cases even new molecules and these made superconduction possible.
