The Great Helium Shortage
The supply of helium, an inert element with the lowest boiling point of any known substance, has now become so erratic that scientists are calling for a ban on all but the most essential uses – which could mean no more helium-filled party balloons. “The scarcity of helium is a really serious issue. I can imagine that in 50 years’ time our children will be saying ‘I can’t believe they used such a precious material to fill balloons,’” said Peter Wothers of Cambridge University.
“There is a finite supply of this lighter-than-air gas on Earth so if we keep using it for non-essential things like party balloons, where we’re just letting it float off into space, we could be in for some serious problems in around 30 to 50 years’ time,” Dr Wothers said.
The shortage has mainly affected research centres studying the brain using magnetoencephalography (MEG) scanners, which are similar to the MRI machines used in hospitals but need to be topped up regularly with liquid helium (helium super-cooled to minus 269C, just four degrees above the lowest possible temperature, absolute zero).
We at bbrooks take the information found in this January 1013 article from The Independent/UK very seriously. As of March 2013, we will no longer be fulfilling requests for balloons.
