MALE PROFESSOR: An often-heard joke about fusion is that a nuclear fusion plant has been "just decades away" from being created for several decades now.

MALE PROFESSOR: Nuclear fusion research is still ongoing, strong as ever in fact.But we still don't have a full scale fusion plant to point to. 

MALE PROFESSOR: And there's a rather big logistical problem as well: how to get the helium-3 off the Moon.

请问老师，But we still don't have a full scale fusion plant to point to是不是等于But we still don't have a full scale fusion plant which we refer to( or mention)？
