About :

In the movie Avatar, future humans invade Pandora, which is 4.37 light years away. The reason humans have gone so far is unobtenium. Just 1 kg is worth 20 million dollars. Humans will do anything to bring this mineral back to Earth. They destroy Pandora's ecosystem and do not hesitate to start a war with the Na'vi. But what on earth is this unobtenium, and why are humans so desperate to have it? First of all, 'unobtenium' is a room-temperature superconductor. A superconductor is a material with no electrical resistance and no energy loss due to heat generation. It also has the effect of repelling magnetic fields due to the Meissner effect.
