What is a Stellarator?

A stellarator is a fusion reactor that uses a magnetic confinement loop to create a specific environment to sustain a revolving plasma. The ‘mobius strip’ design consists of a large metal loop with smaller, different sized magnetic rings surrounding it, allowing for continuous plasma confinement and flow. Stellarators, unlike other fusion reactor designs, operate by uninterrupted plasma flow, allowing for a more consistent output of energy, and can even be used to breed tritium. The video below discusses the background and science of the stellarator concept.
