核聚变能源开启“中国速度”? “人造太阳”正从蓝图走向现实

Core Viewpoint - The article discusses the launch of the BEST research plan by the Chinese Academy of Sciences, aimed at developing controlled nuclear fusion technology, often referred to as the "artificial sun," which promises to provide a nearly limitless source of clean energy and potentially enable interstellar travel in the future [4][11]. Group 1: Introduction to Controlled Nuclear Fusion - Controlled nuclear fusion can replace fossil fuels, providing a sustainable and clean energy source [4]. - The process simulates the nuclear fusion reactions occurring in the sun, continuously releasing vast amounts of energy, thus being termed humanity's "ultimate energy" [4]. Group 2: Advantages of Controlled Nuclear Fusion - Abundant Fuel Supply: The primary fuels for controlled nuclear fusion, deuterium and tritium, are plentiful on Earth. One liter of seawater can yield deuterium equivalent to the energy released from burning 300 liters of gasoline [5]. - Environmental Benefits: The byproducts of controlled nuclear fusion are helium and neutrons, which do not emit harmful gases and have minimal radioactive pollution, making it environmentally friendly [5]. - High Safety Standards: The fusion process occurs in a vacuum container, with the plasma density significantly lower than air, reducing the risk of explosions or leaks [6]. Group 3: Development of Fusion Technology in China - China has designed and constructed several controlled nuclear fusion devices, including EAST, BEST, and CRAFT, which are pivotal to the country's nuclear fusion efforts [7][8]. - The BEST project is set to be completed by the end of 2027, with plans to demonstrate fusion energy generation [11]. Group 4: Future Implications - Successful implementation of nuclear fusion energy could enable humanity to travel to other planets, making interstellar travel a possibility [12]. - The advancements in fusion technology reflect China's strong capabilities in independent innovation within high-tech fields [13].
