(ANSA) - ROME, DECEMBER 12 - The energy from nuclear fusion produced in the USA was obtained in the National Ignition Facility, which studies inertial confinement fusion using lasers.
About 25 megajoules of energy were generated using a laser pulse of just over 20 megajoules.
Nuclear fusion expert Stefano Atzeni, of the Sapienza University of Rome, told ANSA.
"It is - he added - a controlled fusion experiment different from those with magnetic confinement. The result is important because for the first time an amount of energy higher than that used to obtain the reaction was generated".
