From science fair to nuclear fusion

Researchers have proposed a simplified design for nuclear-fusion reactors, based on powerful permanent magnets. The prototype reactors normally require sophisticated superconducting coils to confine plasma in a way that might one day offer enormous amounts of energy. While helping his son with a science-fair project (he wanted to build a rail gun), plasma physicist Michael Zarnstorff realized that neodymium–boron magnets are now powerful enough to be used instead of superconducting coils.
