EnvironmentFusion power may never happen if we don't fix the lithium bottleneck Nuclear fusion power will probably require vast quantities of enriched lithium – but we aren’t making nearly enough, and ramping up production will mean using toxic mercury News
PhysicsAchieving nuclear fusion would be building on the shoulders of giants It took generations of work by engineers and scientists to reach this month’s nuclear fusion milestone, but there are big challenges ahead, says Matthew Sparkes Comment
