We’re running out of helium!

It is the second-lightest element in the Universe, has the lowest boiling-point of any gas and is commonly used through the world to inflate party balloons.  MRI scanners are cooled by the gas in liquid form, and anti-terrorist authorities rely on helium for their radiation monitors, liquid helium is critical for cooling infrared detectors, nuclear reactors and the machinery of wind tunnels. The space industry uses it in sensitive satellite equipment and spacecraft, and NASA uses helium in huge quantities to purge the potentially explosive fuel from its rockets.

Helium is also a non-renewable resource and the world’s reserves of the precious gas are about to run out, a shortage that is likely to have far-reaching repercussions.  There is no way of manufacturing it artificially.

Congress passed a law in 1996 stipulating that the US National Helium Reserve, which is kept in a disused underground gas field near Amarillo, Texas – by far the biggest store of helium in the world – must all be sold off by 2015.

Proud to say I’m a “Liberal”

“If by a “Liberal” they mean someone who looks ahead and not behind, someone who welcomes new ideas without rigid reactions, someone who cares about the welfare of the people — their health, their housing, their schools, their jobs, their civil rights, and their civil liberties — someone who believes we can break through the stalemate and suspicions that grip us in our policies abroad, if that is what they mean by a “Liberal,” then I’m proud to say I’m a “Liberal.”

~ John F. Kennedy, 1960
