I remember hoping as a kid that Helium would explode like Hydrogen (both low atomic number, both start with H, both in balloons) and I tried to make that happen. Turns out it’s inert.

Ohmygodno – hydrogen in toy balloons? If one were accidentally* ignited, it might, I dunno, knock over a leaf or something.

*Accidentally. Yeah, right. Kids with hydrogen-filled balloons and “accidental ignition”.

@Eric: Yes, while the fresh stuff is cheaper, people will use that rather than recycled helium so I doubt many labs use recycled He. At some point in the future it will be economically viable to purify and recycle He. I think the biggest problems with the idea people have to raise the He prices are (1) if scientists pay that higher price then there’s less money for research and (2) raising the prices does not address the future scarcity issue because we have no facilities for long-term storage of He extracted today and since He is essentially a byproduct of oil extraction, we can’t really say “let’s keep that He in the ground and tap it later”.

Isn’t Helium is used to baloons to fly? Man I like it and think all the kids are.

why won’t somebody think of the chipmunk voices

@MadScientist: I also had the initial thought that, in principle, it is easy to purify helium so that it can be reused in medical applications. (That it has a much lower boiling point than anything else is a major plus.) But it’s not 100% effective (helium will slip out in places where other molecules won’t, which is why one of its uses is as a leak detector), and if recycling costs more than using fresh gas, people will go for the fresh stuff.

@gwen: It’s somewhat inexpensive because at the moment there’s actually a huge amount being extracted. The stuff just oozes out of oil fields primarily in the USA. Helium is an alpha particle that picks up electrons so it’s actually a product of nuclear decay; US oil fields just happen to have trapped an awful lot of the stuff. Anyway, what does come out during oil extraction simply has to be compressed and sold. There are no facilities to store huge amounts of helium for use in the distant future; since there is no hoarding, the current large supply keeps the gas somewhat affordable.

Hydrogen is a perfectly good balloon gas and is used throughout most of the developing world – of course you have to take some precautions with the stuff and my bet is that there’ll always be some moron who deliberately puts a light to a hydrogen balloon.

Even if party helium is recovered from medical facilities, helium is fairly easily purified to the level required by the big magnets – it’s not as if the ‘recycled’ helium is not useful to science.

My personal favorite is to increase the number of fast breeder reactors to produce more helium and reprocess more power reactor fuel, but I doubt that’ll be done. Nope – my bet is that we see helium supplies go down. Some clever person’s got to think of a helium-free method of cooling low-temperature superconducting supermagnets.

Someone had that idea at a rally in Armenia recently.

We should totally switch to hydrogen for kid’s balloons! What could go wrong? Just keep the candles at least 100 feet away.

I wondered about that too. It seems to be remarkably inexpensive for such an important gas. Especially since we can’t make it. Yet?
