“We are finally, by harnessing these reactions, getting more energy out of that reaction than we put into the DT fuel,” said Omar Hurricane, who lead authorship of the report. While the accomplishment seems like a small step forward, it represents a welcome degree of progress, as the scientists have been struggling through years of failures to reach this goal.
The nature of these lab experiments involves using a squadron of powerful lasers to crush a very small amount of fuel until it generates heat greater than that of the sun. While the research of the NIF appears to be headed in the right direction, their next goal is to generate more energy than the output of the experiment’s lasers, as opposed to just the fuel at which the lasers are directed. When the experiment can generate over a hundred times its current energy, the process can begin to be self-sustaining.
Although the facility’s funds are derived from the U.S. government as a means to learn about their stockpile of nuclear weapons, the experiments will hopefully educate scientists on how to build a fusion reactor.
