够中国用2万年！我国攻克世界级难题，抢先美国打造“无限能源”。

Core Insights - The article discusses China's advancements in controlled nuclear fusion, highlighting significant breakthroughs in technology and energy production [3][11]. Group 1: Technological Breakthroughs - China has achieved a world record with the EAST device, reaching a temperature of 100 million degrees Celsius and maintaining a stable energy gain of over 1.2 times the input energy for 1066 seconds [3]. - The country has developed a fully autonomous supply chain for controlled nuclear fusion, producing superconducting magnets with a magnetic field strength of 21.7 Tesla, surpassing similar products from the U.S. [5]. - The domestic production rate of core components has exceeded 96%, addressing previous reliance on imports due to international restrictions [5]. Group 2: Resource Availability - Deuterium, a key fuel for controlled nuclear fusion, is abundant in seawater, with each liter containing 0.03 grams, providing enough resources for China to sustain energy production for 20,000 years [7]. - The low extraction cost of deuterium positions China to achieve energy self-sufficiency once controlled nuclear fusion is commercialized [7]. Group 3: Global Positioning - China is leading global research in controlled nuclear fusion, with projects like the "Chinese Fusion Engineering Test Reactor" (CFETR) aiming for grid-connected power generation by 2035 [9]. - The U.S. is facing challenges in its fusion efforts due to fragmented technology and reliance on private capital, making it difficult to catch up with China's advancements [9]. Group 4: Implications for Energy Landscape - The breakthroughs in controlled nuclear fusion technology could transform China's energy landscape, potentially eliminating dependence on fossil fuels and enabling zero-carbon energy solutions [11]. - The commitment and resilience of Chinese researchers have been pivotal in overcoming significant challenges in nuclear fusion research, positioning the country as a key player in the future energy market [11].
