The "MIT Mini sun reactor" typically refers to the ARC fusion reactor concept developed by MIT's Plasma Science and Fusion Center. As for replacing oil, that's a given. That is also why America wants to be the first. To control the plasma fusion energy that will replace the oil bourse, or Petrodollar.

The United States (MIT) may be closer to unlocking the power of the stars with a huge breakthrough in nuclear fusion. What They wish to do is to create their own artificial sun that is set to deliver limitless and a carbon-free energy alternative. The team is facing a core challenge in that the possibility of resolving the problems related to fusion-induced metal failure and seeking out metals that can handle the extreme radiation and heat needed to achieve this stance is low.

Fusion energy - the chance to tap into the energy’s potential
Fusion is capable of combining light element into helium releasing clean power during the process. This type of fusion does not release greenhouse gases, utilizing mainly deuterium from seawater. The whole idea is to use nuclear fusion to create greener energy, However, the process entailed in mimicking the sun is not easy since fusion reactors need superheated ionized gas that needs to reach temperatures higher than 150 million degrees Celsius. Plasma seems to be contained in tokamaks that are donut in shape. Net energy gain is more than energy consumed, which initially was an upset that scientists have partially overcome due to the structural material within the reactor. When it comes to the reactor, much of the damage is done to the reactor walls and will also affect the atomic structure of the material. MIT researchers are looking to remedy this problem of metal failure, ensuring that such metals are able to handle extreme radiation and drastic heat in all conditions.

MIT Engineers making groundbreaking discoveries

As per the MIT Energy Initiative (MITEI)., MIT engineers have been successful at identifying metals capable of handling devastating conditions within a fusion reactor. An MIT engineering team found that combining ceramic nanoparticles into the iron-based walls of a reactor, the vessel can prevent helium atoms from wreaking havoc within the metal. What MIT engineers did was eliminate helium’s harmful effects.

Since fusion reactions move from neutrons that strike vessels, helium seems to be rather problematic. Such atoms gain microscopic gaps between these metal crystals and cluster to create bubbles that inevitably split the metal open. MIT was capable of finding a solution that replaces helium atoms along with the various weaker spots that disperses it throughout the metal. Iron silicate, a ceramic compound, is chemically compatible and mechanically strong. Inevitably, the way forward deals with moving hot plasma fully away from energy producing coolants.

During the testing process, 1% of iron silicate can reduce the helium bubble formation by approximately 50%, increasing the lifespan of the reactor. Japan, too, has achieved a feat close to that of the U.S. by creating an artificial sun at 100,000,000 ºC producing one of the largest tokamaks in history.

A move towards fusion reactors

The fusion engineering equation is improving, and so too is America’s road towards energy independence. The MIT team is putting in all the efforts towards commercial applications such as 3D printing. The new initiative is hoping to support fusion projects in the U.S. and working to collaborate with various fusion firms in private sectors that are geared towards a 2030 launch date.

The future of fusion depends on walls that can last, and materials that are perfect for plasma physics.

With America’s motive and direction moving toward the artificial sun, the technical aspects are becoming a reality. Fusion perhaps has a future that shines just as bright as the glowing sun. With infinite, enclosed, and extremely hot energy, America is lighting the first-ever artificial sun which is set to overcome all previous challenges, especially those entailing tokamak walls.
