Behind closed doors could lie the answer to safe renewable energy of the future. At the National Ignition Facility in Livermore, USA, scientists are aiming to build the world’s first sustainable fusion reactor by ‘creating a miniature star on Earth’.
The $3.5 billion project has inched a little closer to its goal of igniting a workable fusion reaction by 2012. On November 2 they fired up the 192 lasers beams at the centre of the reactor and aimed them at a glass target containing tritium and deuterium gas. The resulting release of energy was of a magnitude of 1.3 million mega joules, which was a world record and the peak radiation temperature measure at the core was approximately six million degrees Fahrenheit.
