**How a Science Journalist Is Analyzing Fusion Reactor Data—Why Its Output Doubles Every 18 Months and What It Means for the Future** In a world racing toward clean energy, a breakthrough fusion prototype is generating intense interest. A science journalist is closely tracking its progression: starting at 75 megawatts, with output doubling every 18 months. With a target of 1,200 megawatts, the question turns urgent: how long will it take to exceed this milestone? Understanding this timeline reveals more than numbers—it offers insight into one of the most promising pathways to limitless, carbon-free power. ### Why Fusion Reactor Growth Is Trending Now The fusion energy sector has made headlines globally, driven by rising climate concerns and escalating investments in next-generation technologies. For decades, clean energy innovation depended on solar and wind—intermittent sources requiring large land footprints and storage systems. Fusion, by contrast, offers plasma-based energy generation with fuel abundancy and minimal waste, positioning it as a transformative alternative. Backed by public and private funding, prototypes are now demonstrating recent leaps, including consistent output doubling cycles. This momentum is now visible in US energy policy discussions, venture capital interest, and media coverage—fusors and officials alike are watching closely as progress accelerates.
