Atmospheric mining is the process of extracting valuable materials or other non-renewable resources from the atmosphere. Due to the abundance of molecular hydrogen and helium in the outer planets of the Solar System, advances in technology may eventually make mining their atmospheres a favorable alternative to mining terrestrial surfaces.
Helium storage and conservation is a process of maintaining supplies of helium and preventing wasteful loss. Helium is commercially produced as a byproduct of natural gas extraction. Until the mid-1990s, the United States Bureau of Mines operated a large scale helium storage facility to support government requirements for helium.
Map showing helium-rich gas fields and helium processing plants in the United States, 2012. From USGS. Helium production in the United States totaled 73 million cubic meters in 2014. The US was the world's largest helium producer, providing 40 percent of world supply. In addition, the US federal government sold 30 million cubic meters from storage.
Gas-rich meteorites are meteorites with high levels of primordial gases, such as helium, neon, argon, krypton, xenon and sometimes other elements. [1] Though these gases are present "in virtually all meteorites," [2] the Fayetteville meteorite has ~2,000,000 x10 −8 cc STP/g helium, [3] or ~2% helium by volume equivalent.
Pure helium-3 gas boils at 3.19 K compared with helium-4 at 4.23 K, and its critical point is also lower at 3.35 K, compared with helium-4 at 5.2 K. Helium-3 has less than half the density of helium-4 when it is at its boiling point: 59 g/L compared to 125 g/L of helium-4 at a pressure of one atmosphere.
As Pulsar Helium inches closer to building Minnesota's first helium drilling operation near the Iron Range, lawmakers and other officials are scrambling to make sure the government can make money ...
It banned the export of helium, for which the US was the only important source, thus forcing foreign airships to use hydrogen lift gas. [1] The Act empowered the United States Department of the Interior and United States Bureau of Mines with the jurisdiction for the experimentation, production , repurification, and research of the lighter than ...
Donald Trump mocked Canadian Prime Minister Justin Trudeau after his top minister’s surprise resignation following a clash on how to handle the president-elect’s looming tariffs.
