Researchers at a laboratory in California say they've had a breakthrough in producing fusion power with a giant laser. The success comes after years of struggling to get the laser to work and is another step in the decades-long quest for fusion energy.
Omar Hurricane, a researcher at Lawrence Livermore National Laboratory, says that for the first time, they've produced significant amounts of fusion by zapping a target with their laser. "We've gotten more energy out of the fusion fuel than we put into the fusion fuel," he says.
