Here’s a first look at the are the unobtainium, the mineral mankind is looking for on the planet Pandora in the movie Avatar directed by James Cameron:
Unobtainium allows superconductivity any loss at room temperature. Superconductivity means that electricity can flow through this material without resistance, no resistance means not loss, so the system becomes ultra efficient: that’s what our grid needs!
Scientists can recreate superconductivity at very low temperatures, but that’s not worth it so far because too much it requires energy is put to reach those low temperatures. At least for now, Superconductivity at room temperature is like a Holy Grail. So you bet that if we were to find a material allowing superconductivity at room temperature we would rush to mine it, even if we would have to get rid of a few aggressive stingy local aliens.
