- An ‘artificial sun’ achieved a record-breaking fusion experiment, bringing us closer to clean, limitless energy (newsbreak.com)
In a groundbreaking development for clean energy, the fusion reactor WEST has achieved a critical milestone in the quest for a sustainable and practically limitless power source. The facility managed to sustain super-heated plasma for an unprecedented six minutes, marking a significant step forward in fusion energy research. This achievement is a precursor to the anticipated capabilities of the larger and more advanced ITER fusion reactor, which aims to extend the duration of sustained plasma to several hours.
Fusion energy, which emulates the process that powers our sun, has the potential to revolutionize how the world generates power. By fusing hydrogen atoms under extreme temperatures and pressures, fusion reactors like WEST can produce energy almost four million times more efficiently per kilogram of fuel than traditional fossil fuels, without the harmful emissions that come with current energy production methods.
In this latest experiment, WEST not only sustained plasma for longer than ever before but also increased the energy output from fusion by 15% compared to previous attempts. This improvement is partially due to a significant update in the reactor’s design, where scientists replaced carbon walls with those made of tungsten. Tungsten was chosen for its durability and its capacity to withstand the extreme heat generated in fusion reactions without absorbing tritium, a radioactive isotope of hydrogen used as fuel in the process.
The successful integration of tungsten and the development of a diagnostic tool to better understand how this material interacts with the plasma are crucial advancements. These innovations address one of the main challenges in fusion energy production: containing the plasma long enough and in a manner efficient enough to generate substantial amounts of energy.
The progress at WEST represents a beacon of hope for the future of energy production, illuminating the path towards a cleaner, more sustainable, and essentially inexhaustible power source. As the global community continues to grapple with the dire consequences of climate change and the depletion of fossil fuels, the successful development of fusion energy could unlock unparalleled opportunities for reducing our carbon footprint and securing energy independence.
