Nuclear fusion. This is the stuff that physicists have dreamed of for decades. The idea of creating more energy, in a controlled environment, than what was put in. Imagine putting only 2 cups of water into a pan, but it allows you to pour out 3 cups. Lawrence Livermore announced they had done exactly that… 2 megajoules in, and 3 megajoules out. This is only a milestone in a long journey, however, proving that it can be done. The scientists expect that it will take 10 years or longer to develop a working fusion reactor. It’s still exciting, when you consider the clean aspects, the lack of nuclear waste, or even threat to common man.
Ignition—when fusion produces more energy than it consumes—is a “significant step closer to the possibility of zero-carbon abundant fusion energy.”
