Fusion is the way that the sun makes power, but recreating a useful fusion reaction here on earth has eluded scientists for decades. The National Ignition Facility target chamber at the Lawrence Livermore National Laboratory is where scientists shoot lasers and watch and measure what happens when those lasers collide on a fuel source. Reaching ignition means the fusion experiment produced more energy from fusion than the laser energy that used to drive the reaction. "For the first time on Earth, scientists have confirmed a fusion energy experiment released more power than it takes to initiate, proving the physical basis for fusion energy. But it's proven extremely challenging to sustain a fusion reaction here on earth, and scientists have been trying for decades.
