What is the largest use of helium?
Could you possibly explain to me, in a straightforward manner, the primary application for helium? I'm quite curious about this element and its diverse usages, but I'm particularly interested in knowing which one stands out as the most significant. Could you also elaborate on why it's considered the largest use? It would be great if you could provide some insights into its economic impact and any potential future trends related to its usage. Thank you in advance for taking the time to answer my inquiry.
