The Process of Nuclear Fusion
Nuclear fusion is the process of combining two atoms to form a single, heavier atom. Unlike nuclear fission, fusion brings atoms together and releases an incredible amount of energy. It requires extremely high temperatures and pressures to overcome the repulsive force between protons. In stars like our sun, protons collide at high speeds, forming new atoms and releasing energy.
Potential of Nuclear Fusion as Energy Source
Nuclear fusion has the potential to be a clean and virtually limitless source of energy on Earth. Scientists are exploring ways to replicate fusion reactions in controlled environments. One approach is using magnetic confinement fusion, where powerful magnetic fields confine and compress a hot plasma to initiate fusion. Another approach is inertial confinement fusion, involving lasers to compress fuel and achieve fusion. Overcoming technical challenges could lead to a sustainable energy source with no harmful byproducts.
