You should study Deuterium much further than the student research paper you linked. The theoretical problems they discuss there don't actually exist.

Again and for the last time: H-3 isn't abundant on the moon or on the earth. Even if it were abundant on the moon, we have zero way of harvesting it. Because of the low concentrations of helium-3, any lunar mining equipment would need to process extremely large amounts of regolith (over 150 million tonnes of regolith to obtain one ton of helium 3)

We can MAKE it out of tritium.... But the amount of tritium production needed far outstrips any benefit.

There's no magic bullets in energy production, s0n.
