No. 3245: HELIUM, THE UP-LIFTING ELEMENT
HOUSTON, TEXAS -
Today, Helium, a noble gas. The University of Houston presents this series about the machines that make our civilization run, and the people whose ingenuity created them.
Helium is the second most abundant element in the universe. Helium is composed of two electrons, two protons, and usually two neutrons. It is a colorless, odorless, inert gas. Helium is a byproduct of both fusion and fission. In 1868, Helium was first detected in the sun's spectrogram. Its name is derived from the Greek word, 'helios' meaning sun.
In 1895, Sir William Ramsay isolated helium. Sir Ramsay also discovered argon, neon, krypton, xenon, and radon, the noble gasses, called noble for their unique properties. They do not combine, they resist forming compounds, and cannot combust. They are regal, alone. Sir Ramsay received the Nobel Prize for adding these noble gasses to our knowledge of the elements.
Helium's mass is 2nd only to Hydrogen. Its atomic number is 2. Its boiling point is nearly absolute zero. Like Hydrogen, Helium is lighter than Nitrogen and Oxygen, the main gases in our atmosphere. This makes them buoyant, lighter-than-air. Helium is so light, that when it escapes that party balloon, it migrates upwards, beyond even the space station. Earth's gravity is not strong enough to keep it inside our atmosphere.
In 1903, a Kansas gas well produced a geyser that would not burn. Helium was found outside of the laboratory. Despite its rarity on Earth, Helium is concentrated in large quantities under the American Great Plains. For millions of years inside the Earth's mantle, natural radioactivity bombarded gas reservoirs stripping away elements, protons, neutrons to the barest, leaving Helium trapped inside gas pockets.
These gas concentrations enabled the United States to have a world monopoly on Helium. The 1925 Helium Act set up the National Helium Reserve in Texas, making Amarillo the Helium Capital for the World. The Act banned the export of Helium. The U.S. would not sell this strategic element to anyone, not the British, not the French, and not the Nazis. Only US airships could use Helium with the advantage of its safety. The Hindenburg fiery crash is known to everyone. But, it would not have happened, if the Germans could have used Helium instead of explosive Hydrogen.
Today's Helium shortages are not its availability. We lose more than 99% by not separating it during natural gas production. The Helium still mixed in the stove gas escapes when we boil water for our coffee. Helium has two possibilities. Use it and lose it. Or, just lose it. Modernizing gas production for Helium could eliminate shortages. This will be useful for deploying modernized airships for delivering global air cargo with clean and green sustainable lighter-than-air technology. Creating an alternate future using a noble gas for a noble purpose.
I'm Don Hartsell, for the University of Houston, and interested in the way inventive minds work.
