There were many reports of this, here’s the IFLS article which reports on the announcement in Nature.
“Using controlled nuclear fusion for a source of virtually unlimited power that is pollution-free has been a dream of physicists since Einstein’s day – but many had written the process off as science fiction. Though it is still a long way off, a new breakthrough has occurred where researchers actually saw a net gain in energy following a fusion reaction. The announcement comes from lead author Omar Hurricane from the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory and was published in Nature. –

I find this news really exciting – to me fusion could be the answer to our enormous energy needs as a completely ‘clean’ source of power – but I am aware that it could also kick off the third world war if it destroys the power of the oil-rich countries. To give us an almost unlimited supply of electricity would allow us to stop the burning of fossil fuels with all the benefits that would bring the planet.
