![]() ![]() Both cases require a high-speed data connection between the operator and the Avatar. EditĪvatars were controlled either by telepresence or by mind upload from the scientists into the avatar body, then mind download back to preserve memories. The flux vortex (the unusual magnetic conditions that allow the rocks to float) allows water to behave in unusual ways, e.g., after falling from the waterfalls, the water evaporates or is magnetically drawn back up to the underside of the rock, whereby it moves upwards via capillary action only to cycle back out at the top again. The mountains are shown surrounded by a significant amount of fog. The rocks quickly condense water from the surrounding fog on their surface and guide it through creeks to the waterfalls on their sides. Heavier rocks lying above the lighter rocks could also help to pressurize the water and push it upwards toward the top of the mountain rather than pouring out half-way down (much the same way as oil is pressurized underground and forced upwards). water can percolate into them, but the lower levels of the mountains are impermeable, thus the water is trapped inside the rocks themselves and do not simply fall out of the bottom. This would not require constant precipitation as the "floating mountains" themselves act as aquifers (rock-made reservoirs) if it can be assumed that the upper layers of rock are permeable i.e. When it rains on Pandora, the water is stored in the rock of the mountains as groundwater (the same as water is trapped in the porous rocks on Earth). Three explanations have been offered that might explain that conundrum. Yet there is no snowcap and no place for enough precipitation to collect in order to fuel waterfalls of that size. We see several floating mountains in the movie having majestic waterfalls, starting from close to the top of the mountain. (He is using the same wheelchair on Earth thus confirming that it is his property.) Edit ![]() ![]() James Cameron also states in his early draft scriptlet that it costs "a million dollars a pound to get something from Pandora back to Earth." The four-minute introduction to Earth that was reinserted into the Extended Edition has Jake reveal that his VA benefits amount to very little money, which implies that he is unable to afford a more advanced wheelchair. As an example, consider the size of the storage locker assigned to Jake and his only having one small sea bag (dufflebag to non-jarheads) of personal gear. As storage space and weight are a concern, a collapsible and portable wheelchair is preferable to a heavier, larger chair. Because the ability to cure paralysis ("get new legs" as stated in the movie) exists, people have never bothered advancing wheelchair technology (or it was phased out over the years). Jake cannot afford something more advanced. Being a former marine, Jake purposefully chose a manually powered wheelchair so he'd still be able to get as much exercise as possible given his condition. As most, if not all, of the military and science crew weren't handicapped (aside from Jake), they wouldn't see a point in spending the money on a more advanced wheelchair. The film does not explain it but viewers have offered several possibilities, including: 1. A line by Jake that was cut from the theatrical version and put back in the Extended Edition reveals that Unobtainium is indeed a superconductor (Jake's line also confirms that Pandora's floating mountains are made of the mineral). One could guess, then, that the mineral is a naturally-occurring "room temperature superconductor", which would be very valuable indeed. Modern science is attempting to create materials that are superconducting at more useful temperatures. Superconducting materials are sometimes shown hovering in a magnetic field in demonstrations, but current superconductors only exhibit such behavior when cryogenically cooled. Another possibility stems from two scenes in which a sample of the mineral is seen floating in mid-air over a relatively small and weak magnet, about the size of the average pincushion. Corporation administer Parker Selfridge ( Giovanni Ribisi) states that it's worth "$20 million per kilo", so its value can be related to items such as gold, silver, gems, and large diamonds. "Unobtainium" is a humorous term used mainly in the aerospace industry to describe the perfect material for an application except for the fact that it does not exist, that it is extremely expensive to make or obtain (hence the name "un-obtain-ium"), or that it is required to violate the laws of physics as the person or persons making the remarks understand them. This is never explained in the film and is considered to be a MacGuffin, a film term for an item that is unimportant except for its part in progressing the plot. ![]()
