The Dawn of a New Energy Era. Energy is now considered part and parcel for modern life, after oxygen and food , energy is third most important thing for human being in this planet.In the quest for sustainable and limitless energy, scientists have long looked to the stars for inspiration. The sun, with its boundless energy, operates on the principle of nuclear fusion a process that has the potential to revolutionize how we power our world. Recently, a significant breakthrough in fusion research has brought us closer to replicating this stellar process on Earth. This achievement, marked by the first successful net energy gain from a controlled fusion reaction, heralds a new era in energy production, promising a future of clean, virtually limitless power. Nuclear fusion is the process that powers the sun and other stars. It involves the merging of two light atomic nuclei to form a heavier nucleus, releasing a tremendous amount of energy in the process.
