During this time, 300 trillion fusion reactions per second occurred in a volume of approximately 1 cubic meter. The plasma had a central magnetic field strength of 5.7 tesla and it carried 1.4 million amps of electrical current.<\/p>\n<p><div class=\"video-container\"><iframe loading=\"lazy\" src=\"https:\/\/www.youtube.com\/embed\/nkMM61e8Ajw?rel=0\" width=\"853\" height=\"480\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/div>\n<\/p>\n<p style=\"text-align: justify;\">Nuclear fusion has the potential to produce nearly unlimited, clean, safe and carbon-free energy. To achieve this end, a<strong> successful fusion requires the product of three ingredients: a plasma\u2019s particle density, confinement time and temperature<\/strong>. When these ingredients reach a certain value, the so-called \u201ctriple product\u201d, the energy released in a reactor exceeds the energy required to keep the reaction going.<\/p>\n<p style=\"text-align: justify;\">The pressure, which is the product of density and temperature, is a key factor in this reaction since it affects two of these ingredients and the amount of power produced increases with the square of it. Therefore, <strong>doubling the pressure leads to a fourfold increase in energy production<\/strong>.<\/p>\n<p style=\"text-align: justify;\">Nowadays, there is still a long way off to get nuclear fusion plants. <strong>These experiments and achievements give scientists more evidences about how move forward<\/strong>.
