Go in-depth with CSU experts on The Conversation.
First, a conversation starter.
- Balloons, sure.
Helium's not only very light, it's also very stable.
And it doesn't react with other materials.
One of the most important uses of helium
is as a liquid in magnetic resonance imaging or MRI.
That's because helium can remain a liquid
at very, very low temperatures.
Liquid helium keeps the magnets in an MRI
cold enough to generate the enormous
magnetic fields needed for high-resolution images.
Without helium, the energy cost
to do that would be huge.
The same principle makes it vital
in making the semiconductors in your cell phone
and in nuclear magnetic resonance research,
which is what I do.
But our supplies of helium are very limited.
To conserve our precious helium resource,
at CSU we've started to recover the helium that we use.
We're already recovering about 50%
and we're trying to bump it
to as much as 90% recovery.
