Home made helium miner? Posted by 1 year ago. Home made helium miner? Would it be possible to build a helium miner at home? You would need a dedicated antenna, but are there any other limitations? Is this supported by the devs? Is the 'LongFi' mentioned on the website a hardware thing or can it be recreated using software. Our large 14.9 cubic foot Balloon Time helium tank fills up to 50 9-inch latex balloons, or 27 18-inch foil balloons. Our small 8.9 cubic foot helium tank fills up to 30 9-inch latex balloons, or 16 18-inch foil balloons. Transporting helium balloons is also quite a hassle-you can find yourself batting them away from your face as they fly around the back seat of your car. The cheaper and more convenient option is to rent a helium tank or purchase a disposable helium tank and fill the balloons with helium at your home or at the party's location.

When we think of uses for helium, most everyone immediately thinks of party balloons, blimps, and high-pitched voices. However, the uses for helium go far beyond just a few novelties. (Never inhale helium, by the way. It can kill you.) In fact, without helium, we may have never had our supermarket checkouts, iPhones, or even the ability to detect tricky cancers.
Below are the different uses for helium that you probably didn’t know existed.And if you need helium for your retail chain or store, why not get a free helium quote from us?
1. The Internet
The tech industry has a lot of interesting uses for helium, including providing you the ability to read this very article. The fiber optic cables that deliver Internet access and cable television to your home and company are manufactured inside of a pure helium atmosphere so that air-bubbles cannot get trapped inside the cable. And while we’re on the topic…
2. Your iPhone
Inside that tablet on your coffee table, smartphone in your pocket, and computer on your desk is a semiconductor chip; a small wafer that houses a set of circuits, which transfer and point electrical currents throughout a device in order to perform specific functions. Helium is used four different ways in the semiconductor manufacturing process: in a specialized cooling process, as a dilutant gas for plasma etching, as a carrier gas for deposition processes, and as a leak detector. All modern electronics, including video games, televisions, and even solar panels rely on semiconductors and therefore, helium.
3. Apollo 13
All of the space shuttle missions, actually. Liquid hydrogen and oxygen are used for the rocket fuel, but helium is needed to clean the fuel tanks out once they’re emptied. Since helium is inert, it will not react and combust with any remaining traces of oxygen that might still be left behind in the tank. It also will not freeze in the pipes like any other liquid would if used to clean the tanks.
4. The Large Hadron Collider
Science has countless uses for helium, but this one’s the biggest. The Large Hadron Collider (LHC) relies on massive quantities of superfluid helium in order to operate. In a three-stage process that takes weeks to complete, nearly 100 tons of helium are cooled to -456.34°F (that’s colder than outer space) so that the giant magnets that the LHC uses to help shoot particles around the 17-mile loop don’t overheat. No helium, no God particle!
5. Nuclear reactors
The energy industry is exploring different uses for helium as well. Next-generation nuclear reactors, or “Pebble Bed reactors,” are high-temperature reactors that are said to be safer and are more affordable than traditional nuclear reactors. The reactor produces heat by using turbines to pass helium gas through the core, which contains a bed of tennis ball-sized “pebbles” made of uranium.
6. SCUBA
SCUBA divers don’t descend underwater with just oxygen on their backs. To create an artificial atmosphere for the diver, that “oxygen tank” is actually a mixture of 80% helium and 20% oxygen. The addition of helium in a high pressure environment makes it easier for the diver to breathe in the air.
7. Emphysema
Some of the most critical uses for helium are in the medical industry. Helium is combined with oxygen for the treatment of asthma, emphysema, and other respiratory problems because the combination gets to the lungs much quicker than oxygen treatment alone. Helium’s also needed for…
8. MRIs
Without helium, hospitals cannot produce MRI scans. The MRI, or “magnetic resonance imaging” uses an extremely powerful magnet to produce detailed images of internal body structures. The high-powered magnet has to be cooled down in order to operate, and with a low boiling point of -452.2°F, helium is the perfect gas for the task.
9. Computer hard drives
Believe it or not, one of the uses for helium is to help your computer remember your files. The first helium-filled hard drives came out in 2012 and were proven to be lighter, faster, and cooler than regular air-filled hard drives. The gas drives have a proven 50% higher storage capacity while using 23% less power, and 10,000 hard drives can be produced on a single tank of helium. In fact, helium performs so much better, that Hitachi Global has stated that it will not even make traditional, air-filled hard drives anymore.
10. Lasers
Although most have since been replaced by diode lasers, low power helium-neon gas lasers were the original red beams used to scan bar codes at the checkout in stores and supermarkets. The original laser pointers also used helium-neon lasers.
11. Ship inspection
Among the more critical uses for helium is leak detection. Since it diffuses through solids three times faster than air, the notoriously hard to contain helium gas is used to detect leaks in the hulls of ships, air-conditioning systems in cars, and high-pressure equipment like vacuums and cryogenic systems.
12. Arc welding
Helium is used in arc welding as a shielding gas because it is non-reactive and allows for a consistent weld at a higher heat transfer, which translates to a higher work speed. Many times, helium is blended with argon gas and the mixture can be adjusted based on the heat, shape of the weld, and speed required by the job. Pure helium is mostly used for seam welding.
13. Microscopes

One of the newer scientific uses for helium is in microscopes. New helium-icon microscopes are being used instead of traditional scanning electron microscopes because of their ability to produce images with much better resolution.
14. Your steering wheel
Hopefully you’ve never needed it, but that airbag in your car actually uses helium gas because of its ability to diffuse quickly. This allows that airbag to inflate nearly instantaneously upon impact.
15. Suicide
Unfortunately, people have figured out that one of the uses for helium is as an effective means of committing suicide. Helium is lighter than air, so inhaling it displaces the oxygen in the lungs. If enough helium is inhaled, the oxygen needed to breathe is pushed out and the individual faces an embolism, rapid suffocation, or even exploding lungs. This is why, despite the funny voices, a person should never inhale helium from a tank or a balloon. And the same goes for helium burping, too.

Rather than combining drugs with the plastic bag, it is also possible to cause unconsciousness using gas. The method is to fill the bag with gas, so that rather than breathing in oxygen, the gas is inhaled instead. This does not interfere with the body's unconscious desire to breathe, but the gas inhaled has no oxygen.
Since the gas being breathed in has no oxygen, what is breathed out has no carbon dioxide. This combats the problem of breathing in air with high CO2 concentration where the body starts to get alarmed.
According to Nitschke & Stewart1, and the Alt Suicide Holiday website2, breathing in a gas with no oxygen content should render unconsciousness in a matter of seconds. Estimates for time to death with this method were not easy to find, although it would seem less than 10 minutes. 20 minutes of gas is said by Nitschke & Stewart to be more than enough to ensure death. Death should be relatively painless, although before being rendered unconscious there will be brief panic knowing that the body is not breathing in air. On discovery, the body will look like death was peaceful.
Tasteless, odourless and non irritating gasses are sensible for this method. Helium, argon and nitrogen all fulfil those requirements, and are readily available to purchase (helium especially).
The method works by running a pipe from the gas container into the bag, filling it with the gas, breathing out fully (important), then placing the bag, emptied of oxygen then filled with gas, around the head, ensuring the bag is sealed to the neck with elastic. The pipe from the gas container must keep flowing into the bag to ensure the gas concentrations are maintained, and a gas flow regulator can be helpful to ensure the gas flows in at a good rate.
A few deep breaths in and out are all that is required to cause unconsciousness (can be up to two minutes though), with death following in around 13 minutes, although can take up to 40 minutes. An 8.8 cubic feet tank of helium should be enough to achieve this, although a bigger 14.9 cubic feet tank better. It is possible to join up two smaller tanks but that adds complication and risk of failure.
It is probably also possible to use a small tent that can be sealed. Ideally pushing out all the air whilst inside it, making sure most air is pushed out before sealing the tent, then filling it up with helium, argon or nitrogen. However, this method might require using more gas, and does not seem to be discussed in suicide literature and forums as the preferred way of performing this method.
Nitschke & Stewart1 in the Peaceful Pill Handbook describe in great detail how to create a reliable 'exit' bag to use with this method. They also discuss recommended gas flows into the bag, how much gas is required and how to regulate the gas flow, thus maximising the chances of swift unconsciousness and the gas lasting long enough to ensure death. Their forum also have numerous discussions on this subject. Helium flow control kits, and gauge & hose kits, are available for sale from the Peaceful Pill Handbook website under 'Buy now'.
Alt Suicide Holiday2 also have extensive information on this method, together with some reports from people who had difficulty using this method, and possible explanations on where they went wrong.
Whilst this method would seem highly effective, certain details must be done right otherwise brain damage is possible. It would be highly advisable for anyone considering this method to consult the videos and text in the Peaceful Pill Handbook first, and check the information on Alt Suicide Holiday.
It is important to be able to breathe freely for this method, as swift unconsciousness relies on taking deep breaths of the gas. Anyone with severe respiratory problems (e.g. emphysema or lung cancer) should not consider this method. Likewise, this method does require some preparation and co-ordination to carry out effectively. It may thus not suit someone who lacks manual dexterity or has no mobility.
This method causes swift unconsciousness so is not recommended for suicidal gestures. There is very little time for a change of mind.
Dangers of this method are permanent brain damage if it is interrupted before completion, as once the brain is starved of oxygen, brain damage starts to occur. It is therefore important that there is no chance of discovery whilst using this method.
Another vital factor is to ensure there is sufficient gas (see above) to ensure death, and that there is no chance of tearing/removing the bag over the head (or tent) whilst unconscious (which might happen if the bag is not fixed snugly and, say, if the attempt is carried out sitting, and unconsciousness results in falling off the chair and the bag becoming dislodged).
