World progress toward fusion energy

Magnetic confinement research has demonstrated the ability to produce controlled thermonuclear fusion conditions in the laboratory. As a result, fusion research is turning from the question of scientific feasibility to the question of engineering feasibility. The author summarizes the rapid progress that has been made in fusion science and technology, as well as what remains to be done. She emphasizes the progress that has been made in building the unprecedented level of international collaboration that is so important for ensuring rapid progress in the future. She discusses the status of fusion science and development, superconducting magnets, plasma heating and fueling technology, tritium handling, materials development, economics and safety, and fusion reactor design
