Japanese Firm Proposes 'Luna Ring' Moon-Based Solar Power System
Shimizu Corporation proposes building an 11,000-kilometer belt of solar panels around the Moon's equator by 2035, using autonomous robots and AI to mine lunar soil and construct arrays. The ring would beam energy to Earth via microwaves and lasers, potentially generating 13,000 terawatts of continuous clean power.
Why it matters
A moon-based solar power system could fundamentally transform global energy production by providing unlimited clean power unaffected by weather or time of day, potentially eliminating dependence on fossil fuels. However, the trillion-dollar cost and technological complexity raise critical questions about resource allocation, who controls space resources, and whether such mega-projects represent genuine climate solutions or distractions from more immediate earthbound options.

Where do you stand?
Should space-based energy infrastructure be developed as an international commons with shared benefits and governance, or through private/national competition that could concentrate control of critical energy supplies?
Is investing trillions in speculative mega-projects like Luna Ring a responsible climate strategy, or should those resources prioritize scaling proven renewable technologies on Earth right now?
How should humanity manage the practical risks—orbital debris, maintenance logistics, and equipment failure—in a system generating 13,000 terawatts that societies depend on for survival?
