Toward Fusion Energy

This book introduces fusion energy as a promising solution for curbing global warming and explains why accelerating its practical use is essential. Designed for beginners—especially undergraduate students—it bridges the gap between introductory and specialized texts. Unlike many existing books that are either too general or heavily mathematical, this book uses clear diagrams and simple arithmetic to explain plasma physics, reactor engineering, and safety. It highlights the ingenuity behind fusion plant components and compares fusion with other power sources through energy conversion efficiency. By presenting key developments in plasma physics and reactor design in an accessible way, this book aims to spark interest in fusion and nurture the next generation of researchers.
