The race toward nuclear fusion, the near-limitless energy source that powers our Sun, is quickly becoming a packed field. Many laboratories leverage tokamaks to confine plasma and induce nuclear fusion while others opt for stellarators, z-pinch devices, and even inertial confinement technologies that blast fuel capsules with an array of lasers. Nuclear fusion comes in all shapes and sizes, and while donut-shaped tokamaks are the most common, many companies and universities are investigating other ways to bring star power in cheaper and more efficient ways. Is nuclear fusion becoming a reality ?
