Helium - the second lightest element in the universe with an atomic weight of 4.002602 - is an inert gas that can be cooled to temperatures of -270 Celsius without becoming a solid, making it indispensible in the operation of, among many things, superconducting magnets used in MRI scanners, telescopes and particle accelerators like the Large Hadron Collider. Helium also holds an important place in the defense industry.
It also has some far less profound applications, which consume great quantities of the gas annually - applications such as party balloons and squeak-voice huffing. These latter applications have drawn the ire of researchers.
This month, the Guardian reported that the UK's Rutherford Appleton Laboratory wasted three days and £90,000 (US$ 143,091), when, during an important experiment exploring the structure of matter, they could not obtain a supply of helium. Needless to say, the scientists were in a less-than-celebratory mood.
"We put the stuff into party balloons and let them float off into the upper atmosphere, or we use it to make our voices go squeaky for a laugh. It is very, very stupid. It makes me really angry,” said Oleg Kiricheck, the research team leader.
Cornell University Professor Robert Richardson is also concerned. He believes that, with our current reserves of helium, the price of the element severely discounts its real value. By his estimation, the price of a single party balloon should cost as much as $100. Richardson suggests increasing the price of helium by 20-50% to eliminate excessive waste.
Although helium ranks next to hydrogen as the most abundant element in the universe, here on earth it is a finite commodity. The helium that is here is all we have!
Helium is collected during natural gas and oil drilling. If the gas is not captured, it dissipates into earth's upper atmosphere and is lost forever. The same happens when a party balloon is released into the air, or when it self-deflates, because helium atoms are so small that they can easily move through the balloon's latex shell.
Party balloons do not represent the only wasteful expenditures of helium. Macy's Thanksgiving Day parade typically uses 400 Mcf a year, although there have been recent attempts to recycle some of the helium used in the floats. NASA uses up to 75 MMcf annually to pressurize rocket tanks. The agency has made no attempt to recycle this huge amount of gas. Weather balloons also consume about 140 MMcf of helium per year.
At the present rate of supply depletion, the United States will become an importer of helium from the Middle East and Russia within 10 years, and the world will run out of helium within 30 years. This would have major implications for space travel and exploration, scientific and nuclear research, medical advances and early detection of diseases.
Possible solutions for this problem should address supply, not pricing. A drastic increase in the price of helium as a preservative measure would cause a huge spike in billing for medical procedures, such as MRIs, scientific research, and defense expenditures, as well as party balloons.
These days, it is often unpopular to suggest government intervention; however, the solution to the complete loss of our helium reserves to some rests under the mantle of regulation. To date, the US government has failed miserably! In 1996, an impulsive Congress decided to sell off all the country's strategic helium reserves by 2015. This resulted in a market that was suddenly glutted with cheap helium because supply-and-demand forces were not established to determine price.
The solution to preventing the disappearance of helium from this planet lies in the scientific and medical communities, whose applications for this noble element are far nobler than those of the world at large. They should, first and foremost, monitor their own processes to prevent waste and attempt to recycle helium as much as possible. Researchers, medical professionals, along with the government, could be helpful in setting up conservation programs to bring public attention to the crisis and its consequences and may go a long way to reduce or eliminate the wasteful use of helium.
Once earth's stockpile of helium is diminished or depleted, the next available source is literally on the moon, where it has been determined that rocks have absorbed generous amounts of helium. As unrealistic as the concept is of establishing mining operations on the moon at the present time, the implications of halting research and meteorological projects, space exploration and medical procedures is unfathomable.
