While we are all waiting for the Avatar 3, here's a little research into element that James Cameron has already used not just once, but twice: the unobtainium. It was the precious rare superconductor that earthlings wanted to mine from Na'vi lands in the first Avatar, but the meaning of 'unobtainium' is not limited to just that. Space whale brain liquid amrita from the Avatar 2 counts as unobtainium as well, and I have a slight suspicion that we might see another unobtainium variety from Cameron in the third part. So, it's time to finally answer some questions regarding unobtainium: what is it, when and why did it appear, and what types of it can you encounter in the wild of the modern science fiction.
