Fracking for helium in Arizona.
Quote:
Though helium is the second most common element in the universe, the gas is hard to find in commercial quantities here on planet Earth. Exception: northeastern Arizona. The region supplied the U.S. with some of the richest deposits of helium in the 1960s and 1970s, and could do so again.
The world now faces a helium shortage, thanks to an ill-advised federal sale of its dwindling stockpiles begun in 1996. Helium cools MRI scanners, particle accelerators, and the chips in your smartphone. It cleans rocket tanks, keeps deep-sea divers breathing, and may yet fill our skies with airships. (Hydrogen, not helium, blew up the Hindenburg.)
