  Experimental evidence of superconductors with critical temperatures above
$373\:K$ is presented. In a family of different compounds we demonstrate the
superconductor state, the transition to normal state above $387\:K$, an
intermediate $242\:K$ superconductor, susceptibility up to $350\:K$, $I-V$
curves at $4.2\:K$ in magnetic field of $12\:T$ and current up to $60\:A$,
$300\:K$ Josephson Junctions and Shapiro steps with radiation of $5\:GHz$ to
$21\:THz$, $300\:K$ tapes tests with high currents up to $3000\:A$ and many
$THz$ images of coins and washers. Due to a pending patent, the exact chemical
characterization and technological processes for these materials are
temporarily withheld and will be presented elsewhere.
