Researchers at the Massachusetts Institute of Technology revealed seven studies that suggest a compact nuclear fusion reactor called Sparc they have been working on should work.
The process of creating nuclear fusion is a particularly challenging one. It requires producing plasma at temperatures of at least 100 million degrees Celsius (180 million degrees Fahrenheit). That level of heat, seven times hotter than the very center of the sun, is considered the fusion threshold.
The Sparc reactor is the most promising development yet in not just proving that reaching the fusion threshold is possible, but actually harnessing the reaction and generating a seemingly endless supply of carbon-free energy.
