Fusion's Break-Even Moment Is Real. It's Not Power Yet
In December 2022 the National Ignition Facility turned 2.05 MJ of laser energy into 3.15 MJ of fusion, a real breakeven. That is science, not a power plant yet.

Science & Space
Space missions, clean energy, and breakthroughs that sound like science fiction until they ship.
Space missions, clean energy breakthroughs, and discoveries that sound like science fiction until they ship. Savviest covers science that matters — launch windows, energy transitions, environmental research, and the physics that changes how we understand the world. We report the findings and the caveats, and we do not confuse a press release with a result.
What we cover

What Doubling the Population Would Do to City Noise
World population hits its 10-billion peak in the mid-2080s, not a doubling. But the hypothetical of a doubled city is still a useful lens: WHO evidence shows a 2x urban population could drive noise exposure and its disease burden sharply upward, on top of the 73,000 premature deaths a year noise already causes in Europe.
