马斯克：建造核聚变反应堆“愚蠢至极”

Core Viewpoint - Elon Musk publicly criticized nuclear fusion power, stating that building small nuclear fusion reactors on Earth is economically foolish, as the sun itself is a massive, free nuclear fusion reactor capable of meeting all energy needs in the solar system [1][6]. Group 1: Solar Energy Advocacy - Musk has previously predicted that solar energy will become the most important energy source for human civilization [3][8]. - In a 2023 podcast, Musk mentioned that a solar panel measuring 100 miles by 100 miles could meet the entire electricity demand of the United States [3][8]. - Musk's latest plan involves deploying 100 GW of solar-powered AI satellites annually, which would equate to about a quarter of the total electricity consumption of the U.S. [3][8]. Group 2: Space Energy Solutions - Musk emphasized that as computing clusters grow, the demand for power and cooling will exceed what ground infrastructure can support [3][8]. - To achieve a sustained computing capacity of 200 GW to 300 GW, large and expensive power plants would need to be built, as a typical nuclear power plant generates about 1 GW [3][8]. - In space, continuous solar energy can be utilized without the need for batteries, as sunlight is always available, and solar panels would be cheaper due to the absence of glass or frames, with cooling achieved through radiation [3][8]. Group 3: Tesla's Solar Business - Tesla's solar business is undergoing a revival, with the company announcing the production of new solar panels at its Buffalo, New York factory, with the first products expected to be delivered in Q1 2026 [4][9]. - Last year, Tesla's solar installation volume hit a low point, leading the company to stop publicly reporting related data [4][9].
