Dennis Letts and Peter Hagelstein start from theory showing that vacancies in palladium deuteride can host molecular D2, conjectured to be necessary for Fleischmann-Pons excess heat. Researchers in the field are sure the Fleischmann-Pons excess heat effect is real and new. In the original experiment, those vacancies probably came from accidental codeposition at high loading. That points to experiments with controlled palladium codeposition, such as the Szpak experiment. They attribute the difficulty of replicating Szpak's work to low deuterium-to-palladium loading. Their modified protocol codeposits at higher current density with less palladium chloride, and every test run so far with it has given positive results, measured by Seebeck calorimetry.
