The word 'helium' is correct and usable in written English.
You can use it to refer to a chemical element with the symbol He and atomic number 2. For example, "Helium is the second lightest element and is used in various industrial and medical applications."
At its most extreme the ban's absurdity was exposed on the BBC comedy mock-news show The Day Today when Steve Coogan, playing a Sinn Féin spokesman, sucked in helium before an interview in order "to subtract credibility from his statements".
We can't get enough of it, but then we will never tire of squeaky-voiced girls who seem to have OD'd on helium just as the nation apparently has an endless capacity to enjoy big-voiced belters.
Recordings included: a cat purring in Brooklyn; office banter in Kosovo; 10-pin bowling in Cardiff; square dancing in Berlin; a steam train in Australia; two lads from Yorkshire talking on helium; clarinet practising in Ayrshire; the sound of the Dutch coast; the dawn chorus in Sefton; doing the laundry in Bangkok; a bootleg clip of a concert in Brighton; and swearing from a traffic jam on the M6.
This will allow astronomers to examine the evolution of galaxies, the formation of planets and the synthesis of chemical elements from the primeval hydrogen and helium that constituted the primitive universe.
Other, slower-burning stars have their light analysed to see how much helium they contain, and thus how long they have been fusing hydrogen to helium to power themselves.The result is a list of 17,000 habstars still quite a lot, but far fewer than if the search were carried out exhaustively.
When flying, only 60% of its lift comes from the helium that inflates it.
The inner two appear, from their densities, to have a lot of water or methane or ammonia in them (or any mixture of the three), along with hydrogen and helium.
Although the helium coolant presents fewer corrosion problems than supercritical water, creating core materials and fuel casings that can withstand the high temperatures involved is a daunting task.
Manufacturers of electronic components love it because they can flood their fabrication tables with helium and it will prevent any other gases or impurities from lodging on the chips.
Natural gas is cooled to the point at which all other gases in the mixture have become liquid and only gaseous helium remains.Its attractions are many.
Such airships will, however, be much cheaper to launch and maintain than satellites and can do things that satellites cannot.Each 75-metre-long airship will be controlled autonomously, and will contain nearly 37,000 cubic metres of helium to keep it and its 1.4-tonne payload aloft, says Michael Molen, Sanswire's chief executive.
