Current uses for helium
Copied from: https://desertmountainenergy.com/helium/
Hard Drives:
Replacing the air in a hard drive with helium (seven times less dense than air) the disks inside create less turbulence as they spin, meaning more discs can be packed into less space and use less power.
Data Centers:
Helium-filled high-capacity hard drives are now used to power industry’s largest data centers, including Netflix video streaming.
MRI Machines:
Liquid helium is necessary to keep the superconducting magnets cool in an MRI machine. This is due to a superconducting magnet’s interesting quantum properties – kept near absolute zero temperature, it will never lose any of its magnetic potential.
Space Exploration:
Helium is also critical to the space industry, used in SpaceX fuel tanks to launch re-usable rockets for satellites and space exploration
Particle Accelerators:
The same concept is utilized in the Large Hadron Super Collider to accelerate particles to near the speed of light.
Google Loon:
Google is launching a network of helium-balloon carried nodes to bring internet to every corner of the world.
Satellites:
Helium is critical to keeping satellite instruments cool.
Deep Sea Diving:
Helium is also used as a gas to breathe in deep-sea diving.
