Engineer: Some people argue that the world' s energy problems could be solved by mining the Moon for helium-3, which could be used for fuel in fusion reactors  But this is nonsense  Even if it were possible to mine the Moon for helium-3, the technology needed to build viable fusion reactors that could use such fuel is at least 50 years away
If the world' s energy problems are not solved before then, it will be too late to solve those problems
mining the Moon for helium-3 is not a possible solution to the world's energy problems
