Japan's Moon Ring: A Solar Belt to Power Earth Remains a Concept
A Japanese firm envisions a 6,800-mile Luna Ring of solar panels around the Moon to supply Earth with continuous power by beaming microwaves/lasers to ground stations; built mostly with robotic construction using lunar soil, it would transcend weather and day/night cycles but faces enormous cost and engineering hurdles, with no funding, timeline, or space-agency backing—it's currently a concept, though related efforts in space-based solar power continue at smaller scales.
