US agency makes game-changing breakthrough with laser-powered energy device: 'One of the most significant scientific challenges ever tackled'

In a big step forward for clean energy, the U.S. Department of Energy's National Ignition Facility has achieved more progress with the world's only net-positive fusion experiment. According to TechCrunch, recent tests have more than doubled the energy yield of the laser-powered system, bringing us closer to a future of affordable, clean power. Nuclear fusion — sometimes called the "holy grail" of clean energy — works by fusing atoms (the opposit…
