If only the market was there for it.

If its the fuel source some claim it to be, I suspect a market would grow pretty quickly among developed nations and reactors were built.
As I understand it, Helium 3 can't even be used to produce weapons.

No one’s built a practical fusion reactor yet; ITER is trying to make the dueterium/trittium reaction work. If they or someone else succeeds then work can begin on the more advanced He3 variant. The fact that He3 can’t be used to make an H-bomb is actually a boon to it’s future as a fuel. If it was in fact dangerous it would only lead to concern about it falling into the wrong hands - an undesirable trait in the “fuel of the future”.
