Ever since when I was young, I loved Superman. And the reason for it is not what you think it is. Because although its agility, his superhuman strength, and his intellect all fascinated me and was incredibly fun to think about, the real reason why I was so captivated and fascinated with Superman was because of where he got his energy from.He didn't get it from a radioactive spider like Spider-Man. He wasn't born as a Norse god like Thor or Loki, but he got it from the yellow sun above us. And that fascinate ...

Summary of Key Points from the Conference Call on Nuclear Fusion Industry Overview - The focus of the conference call was on the **nuclear fusion industry**, which is recognized for having the highest power intensity among all power generation technologies [1][2]. Core Insights and Arguments - **Current Stage of Development**: Nuclear fusion technology is still in its early stages, with expectations to start generating power by **2035** and achieving economic viability by **2045** [1][3]. - **Types of Fusion**: The expert discussed four major types of nuclear fusion: 1. Deuterium-tritium (D-T) fusion 2. Deuterium-deuterium (D-D) fusion 3. Deuterium-helium3 (D-He3) fusion 4. Hydrogen-boron (p-B11) fusion - Currently, the focus is on D-T fusion, but D-He3 and p-B11 are seen as potential next-generation options due to their advantages in energy conversion ratios and safety [3][4]. - **Safety and Technical Barriers**: Nuclear fusion is considered inherently safe due to strict conditions required for the reaction. However, there are significant technical barriers, including high-temperature ignition and material durability against radiation damage [2][5]. Key Projects and Developments - **Global Projects**: Countries worldwide are actively promoting nuclear fusion research. Notable projects include: - **BEST project** in Hefei, China, aiming for net energy gain (Q > 1) and expected to be commissioned in **2028**. - **SPARC project** in the US, utilizing high-temperature superconductors to reduce equipment size and costs, expected to start commissioning in **2026** [4]. - **Investment Opportunities**: Successful operation of these projects could benefit stocks related to high-temperature superconductors and uranium-related stocks due to increased nuclear plant construction [4]. Commercialization and Challenges - **Commercialization Progress**: The pace of commercialization is accelerating, with increasing financing and development of new technologies. However, challenges remain, including: 1. High costs of raw materials (e.g., tritium and helium-3 priced at **USD 20 billion per ton**). 2. Technical barriers related to achieving the necessary high temperatures for fusion reactions [5] [4]. Additional Important Insights - **Breakthroughs in R&D**: Recent advancements in research and development may expedite the progress of nuclear fusion technology, which has been under exploration since the **1950s** [2][3]. - **Market Implications**: The expected growth in nuclear fusion technology could lead to significant market shifts, particularly benefiting companies involved in related technologies and materials [4][5].
Google's data center energy use doubled in four years
