U.S. to announce fusion energy ‘breakthrough’

The aim of fusion research is to replicate the nuclear reaction through which energy is created on the sun. Building devices that are large enough to create fusion power at scale, scientists say, would require materials that are extraordinarily difficult to produce. Even so, researchers and investors in fusion technology hailed the breakthrough as an important advancement. “There is going to be great pride that this is something that happened in the United States,” said David Edelman, who leads policy and global affairs at TAE, a large private fusion energy company. “This is a very important milestone on the road toward fusion energy.”It comes as the Biden administration is prioritizing fusion energy research in its climate and energy agenda.
