Osamu Motojima: Harnessing the 93-million-mile dream

Today, seven members—the European Union, the United States, Japan, China, Russia, South Korea, and India—have formed an organization and invested in what is planned to be the world’s first reactor-scale fusion machine. By 2027, the France-based, multibillion-euro experiment known as ITER aims to produce 10 times the energy it consumes. In this interview, Osamu Motojima, the project’s director general, discusses the skepticism surrounding fusion as a practical energy source, the staggering costs of a large-scale fusion project, and the likelihood that ITER will be the silver bullet that slays the world’s future energy woes.
