There's the rub, if I could answer that I would be rich and famous.

Nuclear fusion.
Nuclear fusion is based on the helium nucleus synthesis from two hydrogen atoms at very high temperatures.
I think you mean "Cold Fusion" It is the (currently) hypothetical nuclear fusion reaction which happens at ambient temperatures?
The sun's energy comes from nuclear fusion, where hydrogen atoms combine to form helium atoms, releasing energy in the process. This nuclear fusion reaction in the sun's core is what produces sunlight and heat.
Nuclear fusion generally requires high temperatures and pressure to occur. In the Sun, fusion happens at temperatures of millions of degrees. While researchers are working on developing ways to achieve fusion at cooler temperatures on Earth, current technology requires high temperatures to overcome the repulsion between positively charged atomic nuclei.
10,000,000 and up.
Nuclear fusion releases huge amounts of energy. It occurs when the nuclei of elements are fused together at high temperatures and high pressure. Fusion energy is used to produce energy for some of the Earth's cities.
The sun is mainly composed of hydrogen and helium heated to extreme temperatures by nuclear fusion.
Nuclear fusion naturally takes place in the core of stars, where high temperatures and pressures allow hydrogen atoms to combine and release energy.
Nuclear fusion requires very high temperatures and immense pressures to start and continue. The problems with a nuclear fusion reactor would be:- 1) the high temperatures would melt the container: therefore, the reaction would have to be stored in a vacuum suspended by a magnetic field and the reactor would have to be continually cooled. 2) nuclear fusion occurs naturally in stars such as our sun: unless the fusion reaction was limited in size in some way, it would be likely that our planet is vapourised by the reaction.
Gravity plays a crucial role in nuclear fusion by compressing and heating the stellar core to the high temperatures and pressures needed for fusion to occur. Higher temperatures and pressures increase the likelihood of atomic nuclei overcoming their mutual repulsion and fusing together. These conditions are found in the cores of stars, where gravity provides the necessary confinement and energy to sustain nuclear fusion reactions.
