Humanity has recently turned its attention to various atoms in its search for a pure, lasting, and limitless source of energy. The mechanism that drives the sun and stars, nuclear fusion, may hold the key to finding the solution. Scientists have been working nonstop to harness nuclear fusion for energy. 

The story of nuclear fusion dates back to the early 20th century, when British physicist Arthur Eddington proposed that the sun and stars produce their energy from a process called nuclear fusion, involving fusing hydrogen atoms to release massive amounts of energy. In the 1930s, the theoretical proof was proven by Hans Bethe, who had mathematically written the mechanism by which stars generate energy through fusion.

However, the first significant breakthrough in achieving nuclear fusion was not until the mid-20th century, with the development of the hydrogen bomb. This weapon combined traditional fission and fusion reactions to produce devastating amounts of heat energy. However, similarly to fission, harnessing fusion for a more peaceful purpose proved to be much more difficult.

Nuclear fusion is the atomic process of fusing two atomic nuclei. The nuclei, typically light in mass, involve isotopes of hydrogen like deuterium and tritium (hydrogen atoms with extra neutrons), to create a heavier atom, releasing extreme amounts of energy in the process of fusion.

Currently, the core method of achieving nuclear fusion involves heating atoms to incredibly high temperatures and pressures, to overcome the repulsion between atomic nuclei, aiding them to close the distance to bind together. Even though the initial amount of hydrogen may seem small, the energy released is extremely high, due to the formula E=mc2, where energy is equal to the mass times the speed of light squared; therefore, allowing even mere kilograms of hydrogen to release enough energy to destroy cities.

One of the most promising methods for achieving controlled and sustained nuclear fusion is magnetic confinement fusion. In these power plants, a heated plasma of hydrogen isotopes is contained in a magnetic field, maintaining the high temperature and pressure necessary for nuclear fusion to occur. Another approach is inertial confinement fusion, which involves compressing a pellet of fuel with lasers or ion beams to create the required temperature for fusion. 
Numerous scientists, companies, and research institutions are developing and investing heavily in nuclear fusion research, utilizing many different creative approaches and innovative technologies to overcome the remaining difficulties.

If we are successful, the potential benefits of nuclear fusion are immense. Nuclear fusion uses virtually limitless fuel, produces minimal waste, and emits no greenhouse gas. Nuclear fusion has the potential to change the global energy landscape in its entirety, providing a clean and efficient source of power to solve the world's energy needs while reducing the risks of climate change. Although challenges remain to reach this goal, the progress made in recent years is enough to bring optimism. As of now, nuclear fusion stands as a beacon of hope for a cleaner and more sustainable future.
