(ANSA) - ROME, DECEMBER 12 - The US Department of Energy will announce tomorrow, in a press conference, that scientists have been able, for the first time in history, to produce a nuclear fusion reaction that generates more energy than is necessary to trigger it.
The Washington Post writes it speaking of "a milestone in the decennial and expensive research to develop a technology that provides unlimited, clean and cheap energy".
For the US newspaper, it is the "Holy Grail" of carbon-free energy that scientists have been chasing since the 1950s.
