The article, published on 4th August 2023, delves into the basics of nuclear fusion, offering an accessible breakdown of its fundamental principles and its potential as a clean and efficient energy source. While the benefits of nuclear fusion are evident, the authors pragmatically highlight the significant challenges that must be surmounted before fusion becomes a practical energy solution. This includes the ongoing quest for suitable materials that can withstand the extreme conditions required for fusion reactions.

Obradors and Puig introduce the concept of a tokamak, a vital component in the fusion process, explaining its functioning and its reliance on advanced superconductors, particularly high-temperature ones, to create and control the necessary magnetic fields. The authors draw attention to global efforts in compact fusion research, with a particular emphasis on the groundbreaking initiatives led by the Massachusetts Institute of Technology (MIT). MIT's work stands out as a promising avenue, with projections suggesting substantial advancements within the coming 10 to 20 years.
