China may have just built the most ambitious solar project in history. Stretching across 400 kilometres of the Kubuqi Desert in Inner Mongolia, a continuous corridor of solar panels now runs three miles wide across what was, not long ago, a sandblasted wasteland responsible for choking Beijing with dust storms every spring. Visible from space and holding a Guinness World Record, the project is so large that it already dwarfs most countries' entire solar capacity. But what makes it remarkable is not just the scale. The panels are also greening the desert beneath them, reducing evaporation, breaking wind, and allowing vegetation to return to land that had been barren for decades. China is calling it the Great Solar Wall, and it is only about halfway done.
