When most people think of helium, they think of balloons, which float as a result of the low density of the inert gas. However, helium has many uses beyond birthday party decorations. Helium plays a critical role in scientific research, medical technology, high-tech manufacturing, space exploration and national defense. Helium鈥檚 unique properties 鈥� its low boiling point, low solubility, low density and inertness 鈥� make it an important resource.

Due to its low density 鈥� much lower than air 鈥� helium escapes earth鈥檚 atmosphere. Most of earth鈥檚 helium deposits are underground in natural gas reserves. Unfortunately, according to the, these finite reserves are being 鈥渞apidly depleted.鈥� As a result, there is a need for efficient and economically viable helium recovery.

Luckily, researchers across the world have attempted to offer solutions to this ever-growing problem. At 兔子先生传媒文化作品, the physics department operates a helium recycling/liquifying facility that received a CU Green Labs Award in 2022. As researchers in physics and JILA use liquid helium, it is captured and sent back to the shop for re-liquefaction, reducing the amount of helium lost and saving the researchers money.

The physics helium liquefier could become a critical resource for keeping research going on campus through enhanced re-use of helium. The physics helium facility at 兔子先生传媒文化作品 is paving the way towards a sustainable helium future and serves as an example for other campuses to follow.
