U.S. scientists create metallic hydrogen, a possible superconductor, ending quest
By Julie Steenhuysen,Reuters 15 hours ago

CHICAGO (Reuters) - U.S. scientists have succeeded in squeezing hydrogen so intensely that it has turned into a metal, creating an entirely new material that might be used as a highly efficient electricity conductor at room temperatures.

The discovery, published in the journal Science on Thursday, provides the first confirmation of a theory proposed in 1935 by physicists Hillard Bell Huntington and Eugene Wigner that hydrogen, normally a gas, could occur in a metallic state if exposed to extreme pressure.

Several teams have been racing to develop metallic hydrogen, which is highly prized because of its potential as a superconductor, a material that is extremely efficient at conducting electricity....

Sounds like a purdy dang expensive conductor.

And there's this question: "A key question is whether the pressurized hydrogen maintains its metallic properties at room temperature"
