Fusion is the process which powers the sun and makes all life on earth possible. In Nuclear Fusion process the energy is produced by fusing together light atoms, such as hydrogen, at the extremely high pressures and high temperatures which exist at the center of the sun (15 million ºC). At the high temperatures experienced in the sun, gas becomes plasma. Nuclear fusion is the most basic form of energy in the universe. It is what powers the sun and all of the stars. It is produced by a nuclear reaction in which two atoms of the same lightweight element, usually an isotope of hydrogen, combine into a single molecule of helium, the next heavier element on the periodic table.

“Globally, the greatest challenge for energy is going to be cooling,” says Martin Freer, director of the Birmingham Energy Institute at the University of Birmingham. “With the growth of the middle class in India and China, there will be an associated demand for air conditioning. The United Nations' Intergovernmental Panel on Climate Change suggest that by the middle of the present century, the demand for cooling will outstrip the demand for heating.”
