Why Do We Need to Think of Renewable Energy?

People in the present world are looking to cater to their energy requirements using renewable energy sources. It is affordable, clean, effectively infinite and domestic. Green energy does not produce any emissions like in fossil fuel burning and everyone will get the opportunity to experience clean water and air as a result of that. In addition, some parts of the world stimulate local economies from the profit that they get from green energy production.

The United States is gifted with some of the best wind resources in the world. Scientists have predicted that this amount is enough to cater 10 times the existing power needs of the country. Wind energy is also recognized as one of the most cost-effective energy generation sources. The cost associated with implementing a wind farm is low when compared to new installations of gas, coal and nuclear power. The low cost of materials such as neodymium magnet that are used in the production of wind turbines has played a major role in the above-mentioned fact. This has even given life to over 400 wind power manufacturing plants within the country.

Having mentioned the importance of wind power, it is also important to consider the wind power manufacturing process as well. Energy is made out of the wind with the help of wind turbines. Usually, these turbines are located about 200 feet above the ground level. These turbines are used to harness the wind and convert them into energy.

When the wind blows, the blades in the n52 magnets turbine are rotated. These blades are connected to a drive shaft that is connected to a generator at the other end. This generator is responsible for the energy generation process. Electricity is generated in the form of alternating current and it can be connected to the national grid without any problem.

During the year 2012, around 2% of the energy requirements in the United States were achieved using wind power. It was able to provide energy for more than 8.7 million homes. When it comes to Australia, wind power was responsible for catering to about 15% of the samarium cobalt magnet needs because of carbon taxes and other restrictions. These percentages are expected to rise within the near future as a rise in demand.

Too Many Wind Turbines Causes “Dirty Air”

The plethora of wind farms added to the U.S. power grid in recent years clearly indicates the rapidly growing demand for wind power. But it is important to know what number is the limit. The scientists believe that with so many turbines running, they might start to lose power instead of generating as they begin to steal the wind created by each other.

This is similar to the experience that is faced by the sailboat captains. If the sailing is done directly downward of another boat, then there is a slowdown. This phenomenon is known as “dirty air”. The reason behind it is that the lead boat tends to create a stormy twister of air behind it when the wind spills as the boat sails. If there is “dirty air” it means there is less power. In a similar fashion the blades of wind turbines produce dirty.

Scientists have designed computer replications to understand what happens at huge wind farms. It is reported that if the wind power is to be increased to supply a major fraction of the energy demand of the world, then these “dirty air” effects will be a matter of concern but exactly how much it will matter is still unknown. This scenario has almost become a riddle for the atmospheric scientists. One must ask when the wind is so “dirty” then what is the point in building an additional turbine?

In order to reach the capacity point, vast wind farms have to be present with thousands of square miles full of turbines and custom magnets. Currently, there are 45,000 big turbines in the U.S. and that is not at all problematic.

According to the calculations of the atmospheric scientist Mark Jacobson, millions of turbines are required to get a serious amount of wind. As more and more wind farms will be set up, the complications will definitely increase. Currently, wind fulfills about 3.5 percent of the electricity requirement in the U.S. According to the wind association, the goal is to raise that to 20 percent by the year 2030. This implies that 75,000 more rare earth magnets wind turbines are required. Therefore, it is important to place the machines at a reasonable distance, to avoid this phenomenon.

The Effects of Extracting Rare-earth Metals in China

The process of extracting rare-earth metals is very disruptive to the environment. The rare earth elements are mined using the open pit mining technique which involves the opening of the surface of the earth using heavy equipment and machinery. During the refining process, there are a lot of byproducts let out into the atmosphere thus polluting it. Extracting rare earth elements is a complex process that involves the use of various acids, solvents, and other chemical-based materials. There are enormous water and energy consumption during the entire process. The entire procedure can produce large amounts of waste water, waste gas and other forms of waste residue.

On February 10, 2019, the Ministry of Industry and Information Technology of China issued the Cleaner Production Technology Promotion Plan for the Rare Earth Industry. According to the Plan, China aims to speed up the industrial application and promotion of the process of separation of low-carbon and low-sodium free ammonia nitrogen rare earth oxide and purification technology along with finalizing the demonstration of the industrial application of rare earth magnets. This is done in order to reduce the acid-base requirement in rare-earth melting and the separation process thus improving the comprehensive use of the rare-earth resources by 2020.

The Chinese government has insisted that the relevant departments should speed up the implementation and promotion of the rare earth advanced clean production technology application for the betterment of the environment. The industrial-technological level of China, in the process of rare earth mining, smelting and separating have made prompt progress in this sector. The implementation of this plan can save 120,000 tons of hydrochloric acid, 373,000 tons of sodium hydroxide or 50,000 tons of ammonia per year. The implementation of the Cleaner Production Technology Promotion Plan for the Rare Earth Industry is a priority for the country’s government.

Disc Technology Highlights a New Frontier

The concept isn’t new but rather formalized as an accepted scientific principle in 2007 with the Nobel Prize being awarded to a European team who discovered Magnetoresistance. The concept forms around the idea that weak changes in magnetic properties develop large variations in electrical resistance. This discovery helped with the popularization of iPods as the first true reliable and long battery lasting handheld technology the world has ever seen.

The Possibilities

The ability to create such a reaction, weak variations in magnetic properties and extreme fluctuations in electrical resistance enabled engineers to establish long play battery life cycles, internal to the hardware specifications set forth by Apple. Other digital devices soon followed suit, and the Magnetoresistance enables greater flexibility in sensitive reading tools, voice coil motors, and calibrations, reducing error potential not only in handheld entertainment platforms but also in medical procedures and prosthetics.

This unique ability allows the neo magnets tools to draw data from hard drives and other similar memory functions. The decrease in utilized power sources brought changes to miniaturization, developments that make the 80s insertion of the Sony Walkman look completely blasé and uneventful. The developments have become standard in the industry in only seven years inserting its potential into the latest pairings with rare earth magnet operations.


Establishing Physics in Everyday Real Life

The Magnetoresistance revolution has become so widespread in popular technology that the industry relies on it for its storage and generative properties. Every popular culture device of the past five years utilizes the process, and it is most grandly inserted deep into industrial technologies as well. Processing speeds have increased a hundredfold in such a short time, while layered data description has sped up to allow streaming capabilities on even the most bargain-basement laptop.

Every piece of technology relies on the process, as miniaturization is the path chosen for advancements in science.

China And Neodymium Industry

For a considerable length of time organization after organization has discussed America's green future. But then, no planning was made to secure the materials we require as a country to make that future an actuality. Presently, that we have left upon that way, we find that the materials we need are not secure. American handling was stopped in light of the fact that we could get them shoddy from China, and the EPA does not need any employments in America that don't include a white lab coat and working in a clean room.

The truth of concentrating minerals and metals from the world's outside oblige forethought to minimize ecological harm. We require more individuals to imagine the new clean techniques for mineral and metal extraction, and less individuals sitting behind work areas devising approaches to close American organizations.

The cost of rare earth metals utilized within lasers and plasma Tvs have multiplied in the most recent two weeks as China tightens control of mining, creation and fares. 97 percent of the 17 components known as rare earths hail from China, and China is flexing its rare earths muscle by cutting fares, boosting costs and starting concern around abroad clients including the US Military.
The majority of the rare earth components are found in gathering 3 of the occasional table: they incorporate the components Scandium; Yttrium; Lanthanum; Cerium; Praseodymium; Neodymium; Promethium; Samarium; Europium; Gadolinium; Terbium; Dysprosium; Holmium; Erbium; Thulium; Ytterbium; Lutetium.

Despite the fact that this emergency has been blending for a few years, however just as of late has the US Congress presented bills, HR 6160 and Sb3521, to address the effect a lack of these materials will have on our economy and our military readiness.

Bills don't prepare rare earths, mining operations produce rare earth magnets. What's more, on the off chance that we begin mining operations now it will a few years before we could handle a small amount of our current interest.
The expense of only one of the rare earths, dysprosium oxide, a key part in magnets, lasers, and in addition atomic reactors, has climbed from $700 to $1,470 a kilogram since the start of June of this current year. The composite cost of eight rare earths has surged to $203.60 a kilogram on June 13, from $92.84 in March 2011, and from $11.59 in 2007.

The cost of each gadget that uses a battery is going to climb and rather significantly, as makers pass the expanded expenses of assembling on to customers.
Rare earths are additionally utilized as a part of autos and resistance provisions. Truth be told, 20 to 25 pounds of rare earth components are found in every last half and half auto made. Rare earth metals are utilized within other cutting edge merchandise, for example, cellular telephone handsets, wind turbines and weapons direction frameworks, and, in laptops, even screen Tvs, and for medicinal supplies, for example, MRI checks.
