This is the third of three posts about helium, and the potential for a world shortage of this unique and wonderful element.
In Part 1, I talked a little bit about why helium is a nonrenewable resource. In Part 2, I tried to achieve a layman’s understanding of the world’s helium markets, and the various reasons why they’ve suddenly become unstable in the past 15 years (after decades of remarkable stability).
This is the last post of the three; it’s more of a list than an essay like the previous posts. Today I’m going to try to outline some of the many wonderful uses that make helium special, and make the case that a total depletion of the Earth’s helium reserves (both helium-4 [4He] and helium-3 [3He] ) would be a tragedy.
We stand to lose much more than party balloons and squeaky voices if we run out of helium.
