Are We Running Out of Helium?
If you’ve been following on the news lately, you’ve likely heard about the possible helium supply crunch. The radioactive element is not a renewable resource, and it is expensive. But did you know that scientists need helium? In a recent article by David Kramer, he explored the potential helium shortage for scientific experimentation. Listed below are some of the ways that scientists need helium.
helium is a nonrenewable resource
Helium is used in various applications, including rocket propulsion systems, lifting gas in blimps, a coolant in MRI machines, and pressurized breathing mixtures. Because of its a very low boiling point, it is often used in liquid form as a coolant. It also plays a vital role in cryogenics, rocket science, and laser pointers. However, most gas is wasted in its current state as a safe lifting gas.
While helium production is steadily increasing, its supply is not. According to the International Atomic Energy Agency, the world has a relatively modest supply of helium, and the demand for it is growing. According to the International Atomic Energy Agency, the U.S. consumes about 56 million cubic meters annually. It supplies just one-third of the world’s supply. Its price remains at $15-18 per liter, and the global shortage is not anticipated until 2023 when the next helium crisis occurs.
Despite being nonrenewable, helium is also precious for military purposes. Since it has a low freezing point, helium is used in purging liquid hydrogen and oxygen. This gas does not freeze and can displace fuels safely. It has been used to extinguish fires in emergencies, including natural disasters. In addition to military uses, helium has a high price tag.
It is a radioactive element
The question of why helium is a radioactive element is a recurrent one among scientists. Its properties are both fascinating and mysterious. Helium is one of the most abundant chemical elements. The helium atom has a spherically symmetric nucleus. The electron cloud is quite similar to its nucleus. However, more complicated nuclei may not have spherically symmetric nuclei.
Helium is a radioactive element, making it a significant chemical and technological material. It can be extracted from natural gas. Helium’s mass in our atmosphere is about 5.2 parts per million. However, this concentration remains relatively constant. This is because most of the helium in our atmosphere escapes into space. It is found in some minerals as a byproduct of the radioactive decay of uranium and thorium.
Though the universe is populated with helium, its supply is quickly diminishing. New helium cannot be produced in a lab. Instead, it forms in the form of radioactive alpha decay in rocks. When this happens, helium starts as a heavier element and splits into two smaller, lighter atoms. In turn, these two lighter atoms are called helium. The resulting radioactive element is helium.
It is a nonrenewable resource
While helium is the second-lightest element on the Periodic Table and the second-most abundant material in the universe, the amount of helium in the Earth’s atmosphere is negligible. Its natural abundance results from the radioactive decay of Earth’s crust. Consequently, it is not practical to collect helium in its natural state. As a result, most commercial helium comes from natural gas deposits, in particular, U.S. and foreign countries.
Helium is used in many applications, including welding. This inert gas shields hot metals from oxidation and other reactions. Unfortunately, the world’s helium supply is near exhaustion, which could have far-reaching consequences. Scientists blame a 1996 law in the United States that made it too cheap to recycle. Although it has a long shelf-life, helium is not a renewable resource means that it will eventually run out.
The long-term supply of helium is dependent on global reserves and plants. For example, the U.S. currently has 4,250 million cubic meters of measured helium reserves. At the same time, the rest is classified as probable or possible. Considering that U.S. and worldwide consumption is about 40 million cubic meters per year, helium reserves would last for about 300 years at the current rate of use. But this scenario is far from a guarantee.
It is expensive
As an element with the lowest boiling point, helium is used in MRI machines and superconducting magnets. It is also used in semiconductor technology. However, the cost of helium is relatively high, and alternative methods are not suitable for all situations. On the other hand, it can be easily recycled indefinitely, making it a good option in certain circumstances. MRI machines rely on helium, but it is not as cheap as some think.
The price of helium varies worldwide, and the supply chain may be the culprit for the price increase. Last year, the U.S. government auctioned its crude helium, forcing prices to jump by nearly thirteen percent. This increase was passed on to customers worldwide and lowered prices in many countries.
Helium is derived from radioactive rocks in the Earth’s crust and is a byproduct of the gas industry. The APS has urged Congress to allow scientists access to the remaining helium supply in the country. However, the organization did not demand exclusive access.
In a letter to congressional leaders on 4 May, APS leaders cited a recent survey of its members to highlight the need to avoid dependence on foreign sources. However, the organization also stressed that price controls are necessary to ensure the supply of helium remains stable. While this would not solve the underlying problem of high costs, it would help maintain a stable market.
It is not readily accessible
The fact that helium is not readily available on Earth does not mean that it does not exist. This rare gas is trapped in various minerals and accumulates in sizeable naturally-formed gas reservoirs. One such resource is the National Helium Reserve.
The process of producing commercially valuable quantities of helium requires thousands of years. For this reason, scientists must search for natural pockets of helium. Until then, the limited availability of helium means that its extraction from the Earth’s crust remains a challenge.
This element is produced deep inside the Earth’s crust. It is created naturally when the radioactive decay of uranium and thorium in the Earth’s crust results in helium production.
As the Earth’s atmosphere expands and contracts, the helium rises to the surface. It combines with air and eventually reaches space. But what makes helium so valuable? Here are a few facts you might not know about this rare gas.
It is a factor in moving magnets
One factor that affects the performance of moving magnets is the amount of liquid helium required to keep them at a constant temperature. For example, a very recent study revealed that about 2,000 cylinders of liquid helium are required to run an MRI magnet for a year. While that amount is still significant, newer versions of the technology require only 300 to 400 liters of helium per magnet.
In addition to being a factor in moving magnets, helium is a critical component for NMR experiments.
The shortage of this gas makes the science of MRI more complex. The shortage has prevented the installation of some instruments, which was delayed due to helium shortages. However, in recent years, a new recycling system has been implemented at the Victoria University of Wellington. This new recycling system has reduced the overall need for helium.
The low boiling point of helium makes it a suitable refrigerant for superconducting magnets. Liquid helium makes superconductors, which are critical components of many MRI machines. Because it produces more required magnetic fields, helium makes MRI scans clearer. It is also widely used in heat transfer, accounting for almost ten percent of the helium supply.
It is used in rockets
Helium is a popular fuel in rockets, but it also has other uses. It is used as an inert-gas atmosphere for welding metals, a coolant in cryogenics, and a lifting gas for balloons. It has also been used for high-pressure breathing operations. Scientists have studied its properties to determine how it is found in meteorites. Interestingly, it is rare in the bloodstream.
The sun produces helium and hydrogen in its atmosphere, but these two elements are not used as rocket fuel. Instead, they are used as fuel tanks and are much colder than liquid hydrogen. Liquid helium is very dense so it would require the same safety precautions as liquid hydrogen.
Since compressed helium has a density of 332 kg/m3, helium tanks could be much smaller than those for oxygen.
The HELIUM project has developed a concept for a near-space European laboratory. In addition, the project has developed life support systems for pilots and a concept for orbiting research at 36 km. The balloon launch system could soon allow tourists to travel to space, although the first passengers will likely be scientists.
In addition to this, a new project called ALTAIR is developing blueprints for a remote-controlled aircraft that can take off and land with sub-200-kilogram payloads.
It is used in party balloons
Why is helium used in party balloons? Although hydrogen is the lightest element in the universe, it is also a highly combustible gas. Consequently, helium is a better substitute for hydrogen as it is non-combustible and does not burn efficiently. Also, it is relatively rare on Earth. Most helium is derived from the radioactive decay of uranium. Once released, helium floats off into space.
The noble gas helium has a surprising variety of applications. Aside from party balloons, helium is used in everything from diving mixtures to high-tech equipment. It is even used in aircraft, airbags, and medical devices. It has been used in party balloons for over 100 years and is essential to modern life. Helium is the second most abundant element in the universe.
Because helium is so tiny, the gas in a helium balloon diffuses through the material of the balloon. Even if a balloon knot is tied around it, some of the gas still gets inside. The pressure inside and outside of a helium balloon balances out once it reaches equilibrium. In hot weather, the gas expands, and the balloon deflates. But this really does not mean that it will not pop in your party balloons.
