4.2.7 The National Ignition Facility
In the following video, Brian Cox looks round the National Ignition Facility (NIF) and observes laser-induced fusion.
NIF has been running since 2009 and is still a way from producing fusion that maintains an overall gain in energy on a large scale.
However, since 2014 they have been able to produce more energy than that required to start the reaction. If you want to read more about this development, read this article from New Scientist [Tip: hold Ctrl and click a link to open it in a new tab. (Hide tip)] (Aron, 2014).
