🌍 Breaking Science & Clean Energy Update!

Fusion energy just hit a major milestone ⚡🌞
China’s EAST “Artificial Sun” has reportedly held stable plasma at densities beyond the Greenwald limit — a key barrier in tokamak fusion research 🔥🧲

🏛️ Context: The Greenwald limit is a known density threshold where tokamak plasma usually becomes unstable. Going beyond it with stability suggests higher-density fusion may be more achievable — bringing future fusion power plants a step closer ⚙️🌍

📘 Why It Matters (UPSC GS Paper 3 – Science & Tech | Energy Security)

✴️ EAST = Experimental Advanced Superconducting Tokamak (“Artificial Sun”)
🌡️ Breakthrough: stable plasma beyond Greenwald limit
🧠 Greenwald limit: density threshold linked to instability in tokamaks
⚡ Fusion basics: light nuclei combine → huge energy (clean energy potential)
🧲 Tokamak: magnetic confinement in a doughnut-shaped chamber
🌍 Global relevance: fusion progress strengthens clean tech leadership + R&D race
🇮🇳 India angle: India’s fusion journey includes ADITYA and SST-1 at IPR, Gujarat
