Scientists at the Korean Superconducting Tokamak Advanced Research (KSTAR) facility ahve managed to break their own record, set in 2019, by holding a plasma ion temperature of over 100 million degrees for 20 seconds.
The previous record, which was 8 seconds, was set by the same research group and crushed the previous record of 100 million degrees for 1.5 seconds.
A “superconducting fusion device” was used to achieve such high temperature. The problem is that this state is hard to maintain, even once it’s reached, but the intense temperatures are enough to actually separate ions from electrons. This mimics conditions thought to be present within our own Sun.
The point to this?
One of the goals is to harness the power of fusion energy. If this works, it could completely revolutionize how the world gets its power and, if it proves to be a clean and sustainable energy source, it may be just what we need to end our reliance on fossil fuels on a massive scale.
