Even more so. But thereās a risk of explosion if youād fool around while smoking. Itās not THAT bad, as it is used in some deep-diving breathing mix instead of helium.
Isaac Asimov was writing about the depletion of helium all the way back in 1977 in āThe Vanishing Element,ā his essay for American Airlinesā on-board magazine The American Way. It keeps coming up as a subject every few years, and sometimes Congress even does something. Seems itās never enough.
Hmm, thatās a bit of an issue. Big bottles are expensive (but bottles of any gas are expensive), lecture bottles are stratospheric-overpriced. But hydrogen is way easier than helium to make; in small scale, a drain cleaner with aluminium foil will do the job. Military, for filling of artillery observation balloons, uses ferrosilicon with sodium hydroxide; that may be an expedient way for higher volumes. Or an electrolyzer; there are many plans online for production of HHO, which is hydrogen-oxygen mixture, which is lighter than air (but stoichiometric and very explosive, more so than hydrogen on its own, and not so light as hydrogen alone). A high-power electrolyzer producing separate oxygen and hydrogen should be doable by modding the design with suitable membranes.
For one balloon or two Iād go the Drano+foil way. For more, for one time job, Iād go with ferrosilicon or similar material. For more regular use, Iād build the electrolyzer or buy an off-the-shelf unit from some alternative energy vendor, there are quite many that sell hydrogen generators.
Itās not quite that simple. The US National Helium Reserve is the source of 30% of the helium sold worldwide right now, so if/when it shuts down there will at the least be a significant effect on market prices. Meanwhile, industrial demand for helium has skyrocketed in the last few decades, and helium extraction mainly comes from natural gasāwhich, as Iām sure weāre all aware by now, is nonrenewable.
Itās like oil. No oneās saying that weāre going to turn the helium tap tomorrow and find that the global tank is empty; rather, itās going to get steadily more expensive as the remaining supplies become harder and harder to access, and (in the long run, if nothing changes) weāll reach a point where extraction stops because nobody can afford to pay for it anymore. There will be blips in the graph when someone opens a major new natural gas field and supplies jump, but the price will continue to trend upward unless we find a major new source.
Of course, the reason they used hydrogen on the Hindenberg in the first place is because back then Texas oilfields were the only major source of helium.
The Republican Congress decided selling off the reserve would be nice symbolism because the reserve originated as a way to keep American military airships flying, and so they get to kill a program that has outlived itās original purpose. Netting some cash to offset the deficit didnāt hurt either. The problem is that this was a myopic view that ignores how helium is important for lots more than just party balloons and the Goodyear blimp.
I was wondering if there is enough helium density in the solar wind that we could just make some sort of (relatively) low speed orbital Bussard collector and skim it off that.
Imagine itās a pretty impractical project though.
If you mean the website, to my knowledge they arenāt particularly responsible. If you mean āpoliticoā generically, youāre absolutely right. Putting the word at the start of the sentence makes it a bit ambiguous .
Also, I retract my Republican comment, as looking back the desire to kill the reserve has been bipartisan. The commentary here is pretty representative of the calls Iāve seen to kill the reserve:
A program that doesnāt now, and probably never, accomplished its initial goal? Check. An expenditure that should have been deemed unnecessary circa 1930 but has nonetheless stuck around beyond the lifespan of most of the Greatest Generation? Check. A function that never had any business being under the purview of the federal government instead of the private sector? Check. A program that has risen, zombie-style from its grave every time someone tries to kill it? Check. A service that crowded out private sector replacements with below-market rates subsidized by taxpayers and then justified its continued existence by complaining the private sector had not jumped to replace it at a loss? Check.
