🚀 Opening: 3 Companies Competing for the Moon's "Dream Fuel"

The lunar regolith holds a secret weapon accumulated over 4 billion years of solar wind — Helium-3 (He-3). An aneutronic fusion fuel that produces almost no neutrons, it is virtually nonexistent on Earth but exists in hundreds of thousands of tons on the Moon.

As of 2026, three pioneering companies are entering He-3 mining through different technological paths. This post provides an in-depth comparison of their technologies, energy efficiency, and commercialization roadmaps.

🔮 Conclusion: Who Will Mine the Moon's He-3 First?

Interlune is furthest ahead with its NASA contract and proven technology. If Prospect Moon succeeds in 2028, it will create a precedent for commercialization.

Black Moon Energy takes a conservative but stable approach, increasing long-term survival probability.

Magna Petra is the most innovative but riskiest bet. If its non-destructive method is proven, it could be a game-changer.

However, all these companies operate under one precondition — D-³He aneutronic fusion reactors must be commercialized. When that day will come, no one knows.

In the next post, we will conduct a deep-dive analysis of the leader Interlune's Prospect Moon technology.
