Helium-3 could power fusion reactors and rewrite the global energy ledger—and the Moon is dripping with it. Interlune’s 110-ton-per-hour regolith harvester is almost flight-ready, China just green-lit a nuclear reactor for its south-pole base, and the 1967 Outer Space Treaty has no sheriff.

With a binding Lunar Governance Accord still only a draft, the race is on to grab ice-rich craters, fence them off as “safety zones,” and corner a trillion-dollar resource before the ink dries. 

Art Grindstone untangles the legal loopholes, OPEC-on-the-Moon scenarios, and open-ledger alternatives that could turn a zero-sum land grab into a shared cosmic commons—if we act before the countdown hits 2027.
