And so if you can win this competition between heating and cooling, you can actually get a runaway reaction, which we call fusion ignition, and thats what happened for the first time in this experiment last month. I want to give special thanks to Mark for sharing his time with us today and on this fascinating topic. Having multiple, diverse approaches to solving it is really critical because we dont know what roadblocks any one approach may run into from a long term if you want to get to energy. The fusion reactions are related to the fusion reactions that take place in the sun. So were very careful about that. Kim Budil, director of the Lawrence Livermore National Laboratory, said there are still "significant hurdles" to overcome with the nuclear fusion technology before commercialization will be possible. For instance, earlier this year, UK scientists generated a record-setting 59 megajoules of energy about 20 times as the US-based project. At 1 a.m. on 5 December, researchers at the National Ignition Facility (NIF) in California finally did it, focusing 2.05 megajoules of laser light onto a tiny capsule of fusion fuel and sparking an explosion that produced 3.15 MJ of energythe equivalent of about three sticks of . We study the transport of radiation in complicated geometries. And very happy to be here to explain a little more about the exciting results that we reported on last month. What are the next steps?
