Question

Quizplus · Accepted Answer

Nuclear fusion currently requires very high temperatures (tens of millions of degrees Celsius) to sustain the reactions, which is a major technical challenge for controlling and using it as a power source. While scientists have made progress in developing fusion reactor technology, there are still significant engineering hurdles that need to be overcome to make it commercially viable.
