Splitting atoms or joining them: the fundamental battle for clean energy
In short: Explore the core mechanics of nuclear fission and fusion. This animated guide explains how splitting heavy atoms compares to the process powering the stars, and why achieving controlled fusion remains a scientific challenge.
The video breaks down the distinct processes of nuclear fission and fusion. Fission involves splitting heavy atoms, such as uranium-235, to release enormous energy through chain reactions triggered by neutrons. In contrast, fusion combines hydrogen isotopes under extreme heat and pressure, the same mechanism that powers the Sun and other stars.
Beyond the basic mechanics, the presentation compares the two methods across several critical factors, including fuel types, required temperatures, and energy output. Notably, fusion is capable of producing 3 to 5 times more energy than fission, yet scientists have not yet achieved controlled fusion on Earth.
