  2. Helium - Wikipedia

    en.wikipedia.org/wiki/Helium

    Terrestrial helium is a non-renewable resource because once released into the atmosphere, it promptly escapes into space. Its supply is thought to be rapidly diminishing. Its supply is thought to be rapidly diminishing.

  3. Non-renewable resource - Wikipedia

    en.wikipedia.org/wiki/Non-renewable_resource

    A coal mine in Wyoming, United States. Coal, produced over millions of years, is a finite and non-renewable resource on a human time scale.. A non-renewable resource (also called a finite resource) is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption. [1]

  4. Lifting gas - Wikipedia

    en.wikipedia.org/wiki/Lifting_gas

    Although abundant in the universe, helium is very scarce on Earth. The only commercially viable reserves are a few natural gas wells, mostly in the US, that trapped it from the slow alpha decay of radioactive materials within Earth. By human standards, helium is a non-renewable resource that cannot be practically manufactured from other ...

  5. Explainer-What is helium and why is it used in rockets? - AOL

    www.aol.com/news/explainer-helium-why-used...

    Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...

    A global helium shortage has doctors worried about one of the natural gas’s most essential, and perhaps unexpected, uses: MRIs.. Strange as it sounds, the lighter-than-air element that gives ...

  7. Earth’s core is leaking, scientists say - AOL

    www.aol.com/news/earth-core-may-leaking-helium...

    While helium-4 is common on Earth, helium-3 is more readily found elsewhere in the cosmos, which is why scientists were surprised to detect a larger amount of the element than had been previously ...

  8. Helium storage and conservation - Wikipedia

    en.wikipedia.org/wiki/Helium_storage_and...

    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.

  9. Atmospheric mining - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_mining

    3D sketch of a Saturn liquid hydrogen tanker. 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.
