China’s $1 trillion fusion reactor sets new record for sustaining temperatures five times hotter than the sun

The transcript discusses a Chinese tokamak's achievement in setting a new record by sustaining a loop of plasma at 70 million degrees Celsius for over 17 minutes, surpassing previous records. It explains nuclear fusion, a process that powers stars, and its potential benefits, such as not producing greenhouse gases or nuclear waste. The challenges of replicating fusion on Earth, like maintaining high temperatures and controlling plasma, are highlighted. The Chinese tokamak's experiments contribute to the International Thermonuclear Experimental Reactor (ITER) in France, expected to be operational by 2025.
