The fact that there are these cities of silicon in our pockets is amazing: https://images.app.goo.gl/qnNSArgbfxPHTyqk7
Also, what happens to an iPhone if you bring it near an ultrasound source with a carefully chosen frequency?
Re ultrasonics - for some MEMS devices yes this can absolutely break things, but because the devices are so small, the resonant frequencies can often be in the hundreds of KHz or even MHz and most ultrasound transducers only produce sub 100khz frequencies

But if you mean any kind of presence/impact than even companies quite far away can be found. You can find products made by companies across the globe literally in the device you are using right now. In my opinion that means a lot more than having a storefront by chance near by.
Still, an interesting find, worth looking into.
I love it when articles have random units of measurements like that!
1 liter of liquid helium expands to .74m^3 of gaseous helium at room temperature. A 16" party balloon has .042 m^3 of space, so requires .05 liters of liquid helium.
So one MRI machine can hold ~30,000 balloons worth of helium and leaks about 39 balloons per day.
Note: This is not to suggest helium that is used for balloons is being redirected from MRI machines. As the article states, helium is captured almost exclusively as a byproduct of natural gas mining and any excess helium not worth capturing is just vented off. Reducing demand for helium by eliminating party balloons would have no affect on the amount of helium that is released from the ground.
Regardless of helium supplies, party balloons are problematic because they tend to escape and contaminate the environment with rubber and plastic. I frequently see empty mylar balloons floating in the ocean.
(I do agree we should conserve it rather than use it for frivolous purposes.)
Interestingly enough, Google told me there are only 14 gasses that are lighter than air. They are:
* acetylene
* ammonia
* carbon monoxide
* diborane
* ethylene
* helium
* hydrogen
* hydrogen cyanide
* hydrogen fluoride
* methane
* methyl lithium
* neon
* nitrogen
* water vapor
Wiki lists most of them at https://en.wikipedia.org/wiki/Lifting_gas , although it leaves out ethylene, methyl lithium, and diborane for some reason. It also doesn't explicitly list carbon monoxide, but talks about it under "coal gas."
Of those, only hydrogen and helium are even vaguely suitable for party balloons, due primarily to their nasty chemical properties and/or expense.

There's a uniquely British phenomenon where large areas are given in terms of Wales. I think it's probably down to our national inability to decide if we're metric or imperial.
There's a right way and a wrong way to deal with quantities. This is a right way:

That's not really a random unit of measurement. It's the only use of helium the audience can be expected to be familiar with.
Also, I can't imagine the seller would be like "hmm, this guy wants to buy gas rights on 87,000 hectares of land for $1. Sounds like a good deal!" without thinking maybe there was something special and investigated for themselves first.
On the other hand, I understand that it is a significant cost driver for industry.
In the 90s, Congress ordered that the strategic helium reserve sell off most of its helium. That tanked the price, which meant it was affordable for party balloons. It also hurt the business of natural gas producers also producing helium.
But helium can also leak irrecoverably out the atmosphere. We should try to hold on to some of it.
It's so cheap that it's commonly used as a welding cover gas as a way to reduce electricity cost and to squeeze more work out of cheaper, lower power equipment. Recycling in the form of capture of storage boil-off, or even collection/retention of helium that can be safely vented from legacy equipment costs substantially more than just throwing it away forever.
But it's useful in ways that nothing else is. MRI is the biggest example, and the largest consumer of helium. There's a whole niche of magnetics that needs helium until science comes up with better magnetics, if that's possible.
Something that doesn't get a lot of detailed attention is leak detection, because there's nothing else that leaks nearly as well (hydrogen molecules are larger than helium atoms!), not to mention safely, as helium. A leaking vacuum jacket means substantial loss of insulation and increased boil-off. Leaking storage of gases is always dangerous - either it's flammable, or poisonous, or an asphyxiant because it's not oxygen, or it is oxygen and everything else is on fire. The process of using helium used for leak detection involves introducing helium into a vessel and looking for helium on the other side. The leak detector itself is a portable mass spectrometer. Leak detection and repair is an extremely rare skill set at any meaningful level of quality, depends on extremely specialized equipment, and it's as expensive as it sounds. If there was a better option, this leak detection niche for helium would be an academic novelty.
Anyway, if this helium source is what it claims to be, it's significant - about 60 years of current production.

With this news I guess it's not as precious as it was last month...
How can someone sell the gas rights for just $1? Whatever they find must be worth more, no? Is there a tax involved when someone extracts resources?
I don't know anything about South African law, but in my home (Alaska) these rights are typically put up for public auction, and yes, there is a further "severance tax" levied on any production that may eventually occur. The (relatively low) auction price is just to lock in exclusivity, generally for a limited length of time. One reason that the initial leases are low is that the actual amount of gas or oil on the property is generally unknown until you get out there and start drilling holes, or at least doing some seismic mapping.
If you find oil or gas and wind up producing it, you then have to pay taxes on that, but if there's nothing there, you haven't wasted your money.
Not all states have a severance tax, though.
That can change if it turns out the actual resources are more valuable, easier to extract, or the liabilities can be resolved with significant investment. Sometimes people throw millions at things too, and don’t really break even. We can’t really see their books here, so we don’t know.
