The U.S. government has not spoken for the time being, but local media has already given broad headlines and positions: For example, The Washington Post points out that this is a "great discovery of clean energy," while Financial Times has brought the headline a "clean energy hope," and The New York Times, for example, has come to the hearing in which we have an afternoon, giving instructions on where and how to proceed. According to these media, for the first time in history, using the world's strongest lasers and bombing a small ball of plasma, they have managed to "produce more than the energy spent" by fusion and positive energy. Through this concrete nuclear reaction "do not pour carbon or generate reactive waste". The result has reportedly been reached at the Lawrence Livermore National Laboratory in California.
They have not recently learned to perform such mergers, the novelty is that they have done a way to gain energy. However, according to the US media, it still takes years to market this type of energy.
