Scientists have achieved a net energy gain in nuclear fusion for the second time, marking major progress towards realising the potential of the near-limitless energy source.
A team at the Lawrence Livermore National Laboratory in California, who first achieved the feat last December, claimed to have passed a new milestone with fusion ignition by producing even greater energy output than the original experiment.
The nuclear fusion process has been described as the “holy grail” of clean energy, as it requires no fossil fuels and leaves behind no hazardous waste. Instead it mimics the natural reactions that occur within the Sun, though harnessing its potential has puzzled scientists since the 1950s.
