awsome.
Holy shit
I remember reading somewhere that this discovery has been around since the eighties. well, if it moves at the same speed without deceleration I suppose you could use it to power something using little to no energy.Quote:

wow that was legit... I love shit like that haha
It's like a futuristic Scalectrix...but really cold
Thats pretty bad ass
It's explained here:

First a thin sapphire wafer is created. It is then coated with a very thin ceramic layer of yttrium barium copper oxide which becomes a superconductor (materials that conduct electricity with no loss of energy) at very cold temperatures. The result is a frozen disc. When it is placed over a magnet, the superconductor material and magnet repel one another due to the Meissner effect (the expulsion of the magnetic field from a material when it goes into a superconducting state). But, because the layer of superconducting material is so thin, some of the magnetic force is allowed through at certain particularly weak points. These paths through are called flux tubes, and they are the real secret to the whole trick. Because there are many of them they cause a three dimensional holding or locking effect, which is what viewers see when watching the video.
Was that Jeff Goldblum doing the interview? Quantum locking looks very interesting - perhaps one step closer to realising the nuclear fusion heat engine by using magnetic fields to suspend the plasma mass. Not sure how you supercool and heat up to a few million degrees centigrade at the same time though!
Fire from ice? Is that when you carve ice into a magnifying lens and use sunlight to start a fire?
I'm pretty sure that superconductivity is a quantum effect, and the people of Association of Science-Technology Centers seem to think so too. Regarding nuclear fusion, no star is self-sustaining - they still need to fuel the reaction (hydrogen initially, then "burning" through the heavier elements) its just that this process takes billions of years. Also stars are only massive because the ignition temperature of nuclear fusion is so high, which is achieved by the gravitational collapsing of dust clouds heating up as they collapse. If the cloud is not large enough, it does not get hot enough to start the fusion process. However, we can use lasers to reach the right temperature on a much smaller mass. The problem with nuclear fusion as an viable energy source is the plasma mass is so hot that there is no material that can withstand the temperature and contain it. Perhaps quantum locking would overcome this problem.
