GENERAL KNOWLEDGE

Detailed explanation-1: -To make fusion happen, the atoms of hydrogen must be heated to very high temperatures (100 million degrees) so they are ionized (forming a plasma) and have sufficient energy to fuse, and then be held together i.e. confined, long enough for fusion to occur.

Detailed explanation-2: -Hydrogen fusion is the most abundant form of energy production in the universe. At the centre of our Sun and the stars, hydrogen is fused using the force of gravitation – at a density more than 70 times the density of steel. Fusion is thus the source of all light and heat on earth.

Detailed explanation-3: -Fusion offers a potential long-term energy source that uses abundant fuel supplies and does not produce greenhouse gases or long-lived radioactive waste.

Detailed explanation-4: -No carbon emissions. The only by-products of fusion reactions are small amounts of helium, an inert gas which can be safely released without harming the environment. Abundant fuels. Energy efficiency.
