The Joint European Torus (JET) already reached the world fusion energy record back in December 2021, but as if that were not enough, it has done it yet again, two years later, during December 2023 with 69 megajoules using a mere 0.2 milligrams of fuel, beating the previous record of 59 megajoules. This is roughly the energy needed for a hairdryer to work for 10 hours nonstop. The importance of this new feat stems from the evident new knowledge that the fusion community has acquired in recent times that has allowed for such a steady advancement in the field.

The DIII-D National Fusion Facility, located in San Diego, California, is the largest magnetic fusion research facility in the United States and is operated by General Atomics for the US Department of Energy. This facility plays an important role in optimizing the tokamak approach to fusion energy production since the mid-1980s and provides valuable data for the engineering design phase of ITER.

DIII-D has recently been in the news because has completed a two-year research campaign that resulted in a record-breaking 1,600 hours of plasma research and 140 groundbreaking studies, leading to many transformative advancements for delivering cost-effective fusion energy.
