A superconductor is a material that will conduct electricity without any resistance. This property would allow the transfer of energy without resistive heat loss enabling greater efficiencies in power transfer. Within electronic devices, this permits operating at lower voltages, higher speeds and without bulky cooling equipment. Achieving superconductivity generally requires cooling metals to near absolute zero which is not convenient for casual users. Until now, Magnesium diboride (MgB2) has been one of the "warmest" superconductors at a balmy 39 degrees Kelvin. Researchers at the Max Planck Institute in Germany demonstrated room temperature superconductivity by compressing hydrogen compounds called silane - produced by bonding a silicon atom with four hydrogen atoms.
