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.
