The energy of the Sun, like that of all other stars, comes from a nuclear reaction known as nuclear fusion. We could say that researching fusion on Earth is, quite literally, an attempt to \u2018bottle a star\u2019 and harness it for our own use.<\/p>\n\n\n\n

To understand it, it is useful to compare it with nuclear fission, which is the technology used in today\u2019s nuclear power stations. Whilst fission involves \u2018splitting\u2019 very heavy atoms to release energy, fusion is the reverse process: it consists of joining two very light atomic nuclei to form a single, heavier nucleus. A huge amount of energy is released during this joining process.<\/p>\n\n\n\n

The \u2018Holy Grail\u2019 of energy<\/strong><\/p>\n\n\n\n

Fusion reactions produce an extraordinarily high amount of energy (about four times that of fission). For this reason, scientists around the world are working to replicate this reaction in a controlled manner on Earth.<\/p>\n\n\n\n

If successful, fusion will become the basis for the reactors of the future, capable of providing a virtually unlimited supply of clean (greenhouse gas-free), safe, and affordable energy to meet global energy demand. A true turning point for the future of our planet.<\/p>\n\n\n\n
