The U.S. Department of Energy (DOE), the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL), and top science media outlets and journals make highly publicized announcement of “positive net energy gain” from presumed fusion ignition. Yet, when the total energy input of the power supply of the experiment is considered, the fusion reaction was a net energy loss greater than 99%. In other words, for every single unit of fusion energy it produces, NIF burns at minimum 130 units of energy, an efficiency of less than 1%. This is far from any “energy gain”.
With the announcement by the US department of Energy “For First Time, Researchers Produce More Energy from Fusion Than Was Used to Drive It, Promising Further Discovery in Clean Power and Nuclear Weapons Stewardship”, the question has been mooted whether we have just witnessed a scientific and...
