수소 저장 혁명: 청정 에너지의 잃어버린 연결고리 찾기

2024년 말, 미국 콜로라도에서 국립재생에너지연구소(NREL)와 GKN Hydrogen이 세계 최초의 500kg 수소 금속수소화물 ‘메가탱크’를 가동했습니다. 일본의 LH2 운반선 스이소 프론티어는 2022년에 호주에서 일본으로 액화수소를 운송하는 데 성공했습니다. Hydrogenious LOHC Technologies는 독일 도르마겐에 연간 약 1,800톤의 수소를 벤질톨루엔 LOHC 시스템에 저장하는 세계 최대 규모의

  • Are OpenAI's multibillion-dollar AI deals fueling a market bubble?
    October 12, 2025, 1:19 PM EDT. OpenAI's multibillion-dollar deals with Nvidia and AMD have reignited concerns about an AI stock-market bubble. Critics warn of vendor-financing-style risk and a circular cash flow that might amplify hype around growth projections. Valuations for AI players have surged—OpenAI near $500B and others climbing rapidly—while reported revenue trails heavy losses. Market moves around Nvidia and Oracle after the announcements show how sentiment is driven by deal news. There’s also a big capex boom among the hyperscalers—Meta, Alphabet, Microsoft and Amazon—spending on hardware to push model performance. Whether the outcome is sustainable depends on turning forecast growth into real profitability, not just lofty valuations and speculation.
  • AMD's Instinct MI450 to use TSMC's 2nm N2, edging Nvidia Rubin GPUs
    October 12, 2025, 1:17 PM EDT. AMD’s Instinct MI450-series accelerators, based on CDNA 5, will be built on TSMC’s N2 2nm-class process and debut in H2 next year. This marks AMD’s first use of a leading-edge node for AI GPUs, potentially giving it an edge over Nvidia’s Rubin GPUs on N3. Lisa Su highlighted the collaborative, village-like approach to assembling the system. N2 promises ~10–15% higher performance at the same power (or ~25–30% lower power) and ~15% greater transistor density over N3E, aided by GAA transistors and DTCO. Nvidia’s Rubin-based NVL144 will offer higher FP4 performance, but AMD’s Helios rack-scale with 72 MI450 GPUs should feature up to 31TB of HBM4 and 1,400 TB/s bandwidth vs Nvidia’s 21TB and 936 TB/s. Real-world results depend on interconnects like UALink.
  • Cities Push Back Against Flock Safety License Plate Cameras
    October 12, 2025, 1:16 PM EDT. Cities are pushing back against the nationwide spread of Flock Safety license-plate cameras, challenging the company’s contracts and its law-enforcement reach. Critics warn the devices create surveillance databases that go beyond simple plate reads, with features like a Vehicle Fingerprint potentially tracking cars without plates. In Colorado, Illinois, and Texas, several agreements have been canceled or scrutinized amid questions of legality and access by federal agencies. Evanston, IL, forced Flock to remove 19 cameras after regulators found U.S. Customs and Border Protection access violated state law, prompting cease‑and‑desist actions and partial re-installations. As debates intensify over privacy, civil-liberties concerns and the proper limits of surveillance tech in policing, municipalities are re-evaluating partnerships with the startup.
  • Tesla Model Y Performance Gains with Unplugged Aero Kit: More Downforce, Less Drag
    October 12, 2025, 1:14 PM EDT. The Tesla Model Y Performance gains enhanced handling and appearance thanks to Unplugged Performance's new aero kit. The kit claims a 2.4% drag reduction and improved net downforce for better grip and highway stability, without promising a range increase beyond the stock 306 miles. It comprises five components: front lip splitter, front aero canards, high-efficiency rear fins, high-efficiency rear diffuser extension, and high-efficiency trunk spoiler—all available individually or as a complete set. Full aero kit price is $2,195; adding satin or gloss mirror covers brings it to $2,595. Individual parts range from $295 for the rear fins to $475 for the high-efficiency part. Finished to OEM standards and CFD modeling, the kit also claims better crosswind tracking.
  • Class of AI: Advice for Students Entering a Workforce Shaped by Artificial Intelligence
    October 12, 2025, 1:13 PM EDT. AI isn’t a distant fantasy—it’s here and reshaping entry‑level work. Tools like ChatGPT and Copilot can draft reports, analyze research, and build slides in minutes. But they’re a supplement, not a replacement. The message is clear: develop AI literacy and learn to prompt, refine outputs, and spot errors. Use AI to automate routine tasks so you can focus on creative and strategic work, and to prove yourself by adding real value. Experts like Jennifer Woods and Jade Walters emphasize that AI will evolve and become integral; the trick is to leverage it without letting it erode your own voice. So lean into AI, practice responsible use, and build competencies that will outpace the automation you’ll encounter.
