How close are we to powering the world with nuclear fusion? - George Zaidan (2024x52)

: 27, 2024

Stars have cores hot and dense enough to force atomic nuclei together, forming larger, heavier nuclei in a process known as fusion. In this process, the mass of the end products is slightly less than the mass of the initial atoms. But that “lost” mass doesn’t disappear — it’s converted to energy ... a lot of energy. So, can we harness this energy to power the world? George Zaidan investigates. Lesson by George Zaidan, directed by Igor Ćorić, Artrake Studio.
