A Japanese company, Shimizu Corporation, has proposed an ambitious concept known as the “Luna Ring”—a huge belt of solar panels stretching around the Moon’s equator to generate energy and beam it back to Earth using microwaves or lasers.
The idea is based on real advantages of the lunar environment, including the absence of atmosphere and weather, which could allow more efficient solar energy collection. If such a system were ever built, it could theoretically produce vast amounts of clean energy.
However, this remains a conceptual proposal, not an active or approved project. Major challenges—such as construction on the Moon, energy transmission efficiency, cost, and safety—are still far beyond current capabilities.
