The ‘breakthrough’ announced by the US National Ignition Facility has focused the spotlight on nuclear fusion. NIF reported a net energy gain (more output than input), which is deduced to have come from two nuclei of hydrogen atoms fusing to form a helium nucleus. But this is a baby step; there is a lot of runway to cover before nuclear fusion takes off, experts say.
But developments elsewhere seem to challenge this view.

It has raised $2 billion from the likes of Bill Gates, Google, Eni, Khosla Ventures, Soros Fund Management, and Temasek.
In collaboration with MIT’s Plasma Science and…
