The breakthrough was made by a team of scientists at the Lawrence Livermore National Laboratory’s National Ignition Facility in California on December 5 – a facility the size of a sports stadium and equipped with 192 lasers.“This milestone moves us one significant step closer to the possibility of zero-carbon, abundant fusion energy powering our society.”Granholm said scientists at Livermore and other national labs do work that will help the US move quickly toward clean energy and maintain a nuclear deterrent without nuclear testing.“If we can advance fusion energy, we could use it to produce clean electricity, transportation fuels, power, heavy industry and so much more.”Arati Prabhakar, director of the White House Office of Science and Technology Policy, spoke about how, as a young scientist early on in her career, she spent three months at Lawrence Livermore working on its nuclear fusion project.The US project, while groundbreaking, only produced enough energy to boil about 2.5 gallons of water, Tony Roulstone, a fusion expert from the University of Cambridge’s Department of Engineering told CNN.Neither the US or UK-based projects “have the hardware and steps in place to convert fusion neutrons to electricity,” Anne White, head of MIT’s Department of Nuclear Science and Engineering, told CNN."
