For the first time in history, US scientists at the National Ignition Facility at the Lawrence Livermore National Laboratory successfully produced a nuclear fusion reaction resulting in a net energ…
that powers nuclear reactors around the world today. Like fusion, the heat created from splitting atoms is also used to generate energy.. But it produces volatile radioactive waste that must be stored safely and carries safety risks. Nuclear meltdowns, although rare, have occurred throughout history with wide-ranging and deadly results such as at the Fukushima and Chernobyl reactors.
The big challenge of harnessing fusion energy is sustaining it long enough so that it can power electric grids and heating systems around the globe. The successful US breakthrough is a big deal, but it’s still on a far smaller scale than what’s needed to generate enough energy to run one power plant, never mind tens of thousands of power plants.
Why is DOE’s forthcoming announcement about a fusion reaction resulting in a net energy gain important? While there’s many more steps until this can be commercially viable, it’s essential for scientists to show that they can create more energy than they started with. Otherwise, it doesn’t make much sense for it to be developed.
