马斯克给核聚变泼冷水：愚蠢且浪费

Core Viewpoint - Elon Musk criticizes the construction of small nuclear fusion reactors, labeling it as a foolish and wasteful endeavor, suggesting that solar energy is a more viable and cost-effective alternative [1][2]. Group 1: Cost and Efficiency - Musk argues that the costs associated with building small nuclear fusion reactors far exceed those of utilizing solar energy directly [2]. - He highlights the inefficiency of replicating the sun's nuclear fusion process on Earth, emphasizing that solar energy is abundant, free, and more efficient [1][2]. Group 2: Timeline and Commercialization - Musk points out that nuclear fusion is still a long way from commercialization, estimating it could take around 23 years for practical applications to be realized [2]. - He advocates for focusing on mature technologies rather than investing in the uncertain future of nuclear fusion [2]. Group 3: Alternative Energy Solutions - Musk proposes the "solar AI satellite plan," which aims to harness solar energy from space, avoiding land use and minimizing energy loss due to weather conditions [2]. - He believes this approach represents the most economical, efficient, and clean energy utilization method available [2]. Group 4: Investment Trends - Despite the rapid growth in investments in nuclear fusion, with global funding increasing significantly each year, Musk's stance diverges by promoting solar and energy storage solutions instead [4]. - The stock prices of domestic companies related to nuclear fusion have surged in the past two years, particularly this year, indicating a strong market interest [4].
