地球上造小型核反应堆“愚蠢至极”，马斯克：太阳才是“免费终极核反应堆”

Core Viewpoint - Elon Musk criticizes the efforts to build small nuclear fusion reactors on Earth, calling them "extremely foolish" and emphasizes that the Sun is the ultimate "free fusion reactor" [3][6] Group 1: Musk's Perspective - Musk argues that investing in small fusion reactors is a waste of resources, urging companies to stop funding these "pet science projects" [3][6] - He uses a striking analogy to highlight the Sun's energy dominance, stating that even if four Jupiters were burned, the Sun would still account for nearly 100% of energy production in the solar system [3][4] Group 2: Silicon Valley's Investment Trend - In stark contrast to Musk's views, major tech companies like Nvidia and Google are heavily investing in nuclear fusion technology, aiming to leverage AI to accelerate its commercialization [6][7] - Commonwealth Fusion Systems recently announced an investment of $863 million, with Nvidia among the investors, indicating strong financial backing for fusion projects [7] - Google's AI subsidiary, DeepMind, is collaborating with Commonwealth Fusion Systems to utilize AI in developing grid-compatible fusion energy solutions [7] Group 3: Government Support and Future Plans - The U.S. government is actively supporting fusion technology, with the Department of Energy releasing a new "fusion roadmap" aimed at integrating fusion energy into the U.S. energy structure by the early 2030s [7] - The International Atomic Energy Agency (IAEA) notes that global fusion projects are entering a critical phase aimed at unlocking safe, abundant, and zero-carbon energy [7]
