Startup Raises $15 Million to Mine Moon for Nuclear Fusion Fuel
- Company named Interlune raised $15 million to mine helium-3 from the moon
- Helium-3 is a rare helium isotope that could power Earth for a year with just 25 tonnes
- Earth's atmosphere doesn't contain enough helium-3 to meet energy demands
- Mining the moon is the only way to acquire enough helium-3 fuel
- If successful, helium-3 from the moon would power Earth with high-energy fuel
