Core Viewpoint - The article argues that nuclear fusion, often touted as the "ultimate energy" solution, is not a viable option for meeting future energy demands, particularly in the context of AI advancements. It highlights the misconceptions surrounding nuclear fusion and presents a critical analysis of its feasibility and practicality [1]. Summary by Sections 01: The Myth of Nuclear Fusion - Nuclear fusion is perceived positively due to three main advantages, but these are misleading and not practical [2]. - The claim that seawater contains abundant fuel for nuclear fusion is deceptive; while deuterium is present, it requires tritium, which is not naturally available and must be produced through complex processes [3]. - The assertion of zero pollution and risk is true, but the low energy output of fusion makes it impractical for power generation [4]. - The energy density of fusion fuel is often confused with its power density; while fusion fuel has high energy density, its power output is significantly lower than that of fission reactors [6]. 02: Fundamental Issues with Nuclear Fusion - The power density of nuclear fusion is 20 times lower than that of nuclear fission, necessitating much larger reactor sizes to produce equivalent energy [7][9]. - The cost of building a nuclear fusion power plant is projected to be at least three times higher than that of a fission plant, with estimates for a fusion reactor reaching up to $150 billion for equivalent output [11]. - The sustainability of fusion fuel is limited, with available resources lasting only a fraction of the time compared to fission fuel, contradicting the notion of "unlimited" energy [16]. 03: Misconceptions Surrounding Nuclear Fusion - The belief that fusion technology is on the verge of commercial viability has persisted for decades, yet significant breakthroughs remain elusive [18]. - The narrative of fusion being a clean and environmentally friendly energy source is politically motivated, but economic feasibility is questionable if the cost of electricity remains high [20]. - The use of complex terminology in fusion discussions often serves to obscure the fundamental issues and lack of practical solutions [21]. 04: Alternative Energy Solutions - Upgraded nuclear fission technologies are presented as safer, more cost-effective, and capable of recycling waste, making them a more reliable energy source for the future [20]. - Renewable energy sources, such as wind and solar, combined with advanced storage solutions, are positioned as complementary to nuclear fission, providing a stable and sustainable energy system [21]. 05: Conclusion - The article emphasizes the need to focus on practical energy solutions rather than relying on the unrealistic promises of nuclear fusion, advocating for advancements in fission technology and renewable energy systems to meet future energy demands [22].
