Hvad bruger den amerikanske regering helium til?
National Helium Reserve, også kendt som Federal Helium Reserve, er en strategisk reserve i USA med over 1 milliard kubikmeter (109 m3) heliumgas. Heliumet opbevares i Cliffside Storage Facility ca. 19 km nordvest for Amarillo, Texas, i en naturlig geologisk gaslagringsformation, Bush Dome-reservoiret. Reservatet blev oprettet med vedtagelsen af Helium Act of 1925. Den strategiske forsyning leverede ædelgassen til luftskibe og blev i 1950'erne en vigtig kilde til kølemiddel under den kolde krig og rumkapløbet.

The helium is stored at the Cliffside Storage Facility about 12 miles (19 km) northwest of Amarillo, Texas, in a natural geologic gas storage formation, the Bush Dome reservoir. The reserve was established with the enactment of the Helium Act of 1925. The strategic supply provisioned the noble gas for airships, and in the 1950s became an important source of coolant during the Cold War and Space Race.
