Helium-3 is a pipe dream. There is no practical source to get any quantity of it, so its usefulness as a fuel and energy source is basically nil. That article talked about the moon as a source for thousands of years worth of energy... except it would require a moon base far larger than any current plans could achieve in even a hundred years. The moon base would then have to collect tons of dust from the surface of the moon, and heat it to extremely high temperatures, and then seperate the Helium-3 isotopes from anything else that comes out. Then it would have to be shipped back to Earth. Overall, to see it become an energy source, we would need a space elevator to reduce the costs of shipping supplies up to the moon, and retrieving Helium-3 from the moon, and a substantial base on the moon, amounting to a factory... one that will also need a very powerful and precice radar station, and the capability to deflect any incoming meteorites or the ability to absorb the impact... unless you built the majority of the base underneath the surface, which would take even longer and cost even more. To address energy concerns now, it's simply not an option.

Oh, and Renegade... Helium-3 fusion is usually understood to be with deuterium, and Hydrogen fusion is usually either four protons fusing or deuterium/tritium fusing. The difference in mass between Helium-3/deuterium and deuterium/tritium is negligable, and technically the Helium-3 would mass slightly less because it has an extra proton rather than a neutron. But the mass isn't the issue, it's the charge. To get two nuclei to fuse, they have to overcome the EM energy forcing them apart, until the strong nuclear interaction takes hold, and the new nucleus is formed (with a lot of energy). The helium fusion would take a little more energy to cause the collisions compared to the deuterium/tritium fusion, and both would take a lot less than four protons. As a kind of analogy, try forcing two north poles of magnets together; that's deuterium/tritium. Now, try the same with one magnet being about twice the strength; that's Helium-3/deuterium. And finally, take four magnets, and try to force them all together; that's four protons.
