"These and other scientific, technological and engineering hurdles will need to be overcome before fusion will produce electricity for your home. Work will also need to be done to bring the cost of a fusion power plant well down from the US$3.5 billion of the National Ignition Facility. These steps will require significant investment from both the federal government and private industry."
If fusion research scientists continue to insist that their research has any viable path to use in commercial power generation, and to demand large amounts on funding on that basis, then they should expect to be critiqued on that same basis.
