South Korea's nuclear fusion program hit 100 million degrees Celcius for about 30 seconds before being shut down over hardware limitations. Unlike existing nuclear-fission power, the non-radioactive fusion energy production process simulates the sun's energy production.
The power of the sun in the palm of our hands?? There are still decades until humans can genuinely tap into fusion energy. The process creates plasma that must be contained which currently has no specific solution. But this is a big step toward the clean energy that may sustain earth 100 years from now.
