Two U.S. Department of Energy scientists with the Advanced Research Projects Agency-Energy (ARPA-E) plan to give a presentation on progress in nuclear fusion research at the annual meeting of the American Physical Society on Wednesday.<\/p>\n
Samuel E. Wurzel serves as a technology-to-market advisor for ARPA-E. Scott C. Hsu serves as a program director for the agency.<\/p>\n

On May 23, 2021, Wurzel and Hsu published a preprint of peak triple-product values from many fusion reactor types. The caption of their graph explains that the displayed values are those that set a record for a given [reactor] concept vs. year achieved.<\/p>\n<\/p>\n
New Energy Times examined only the experiments in the tokamak reactor design category. The graph below isolates only experiments from that category.<\/p>\n<\/p>\n
However, although Wurzel and Hsu displayed values for non-tokamak concepts through the year 2017, they omitted all data in the tokamak category from 1995 onward.<\/p>\n<\/p>\n
Table 2 from Version 1 of their pre-print, which appears as Table VI in Version 3 of their pre-print, provides an extensive list of fusion experiments performed in tokamak reactors. Wurzel and Hsu excluded all tokamak experiments beyond 1995.<\/p>\n<\/p>\n
For a more accurate and honest display of progress in nuclear fusion in the last 70 years, New Energy Times published a report for readers and investors called When Will We Get Energy From Nuclear Fusion?<\/p>\n
The latter part of that report presents a preliminary discussion of the awkward fact that one of the two required fuel sources for fusion tritium does not exist as a natural resource on Earth. This fact casts a dark cloud over the long-running sensationalist claims that the fuel for fusion is virtually unlimited.<\/p>\n
A subsequent New Energy Times report provides the full discussion of the fusion fuel limitation.<\/p>\n<\/p>\n
