OpenStar A New Zealand startup claimed that its experimental reactor created plasma, a first, critical step for nuclear fusion. The same process that fuels stars, nuclear fusion promises a source of abundant energy, but commercializing it has proven elusive. OpenStar’s prototype, which it calls “Junior,” is a long way from true nuclear fusion, but it suggests that its unconventional design, which essentially inverts the traditional donut-shaped reactor design by placing the magnet inside at the reactor’s center, could, one day, actually work: “It’s the only fusion configuration that nature doesn’t want to destroy immediately at all times,” its CEO told IEEE Spectrum. |
