Dennis J. Cravens is an American physicist and educator known for his research and public demonstrations in the field of Cold Fusion, also referred to as low-energy nuclear reactions (LENR) or the anomalous heat effect (AHE). He earned his doctorate from Florida State University and has investigated claimed excess-heat phenomena since 1989, the year the field emerged following the announcement by Martin Fleischmann and Stanley Pons. He resides in Cloudcroft, New Mexico. His work lies outside the mainstream of accepted physics, as the reality of cold fusion is not recognized by the broader scientific community.
Biography
Cravens received his PhD from Florida State University. In addition to his research activities, he has taught mathematics and science, including online courses. He has described his primary interest as examining questionable or discarded physical theories to determine whether they hold any merit and whether they might be applied to practical ends.
Early in his career he was associated with ENECO, one of the first companies formed to develop commercial applications of the Fleischmann–Pons effect, and he was engaged to evaluate prototype devices such as the Patterson Power Cell. He has been a long-time research collaborator of Dennis Letts, with whom he has co-authored papers and jointly built experimental cells.
Scientific contributions
Cravens is known within the cold fusion research community for his systematic study of the conditions that trigger excess heat in palladium–deuterium (Pd–D) systems. Over more than two decades of experimentation with the anomalous heat effect, he investigated a range of possible triggering mechanisms, including heat, pressure, electric current, radio-frequency stimulation, chemical loading, laser stimulation, acoustic effects, and magnetic fields. Much of this work was carried out in partnership with Dennis Letts, and included laser-resonance studies pursued with theorist Peter Hagelstein.
He presented "Factors Affecting the Success Rate of Heat Generation in CF Cells" at the Fourth International Conference on Cold Fusion (ICCF-4) in Maui in 1993, and reported his investigation of the Patterson Power Cell using flowing-electrolyte calorimetry at ICCF-5 in 1995, where a live demonstration of the cell was also shown. With Letts he presented "The Enabling Criteria of Electrochemical Heat: Beyond Reasonable Doubt" and work on laser stimulation of deuterated palladium at ICCF-10 in 2003.
Cravens is noted for conducting live public demonstrations of claimed LENR devices. At NIWeek 2013 he displayed a self-contained sphere reported to produce measurable excess heat, and at ICCF-21 he showed a live video feed of an operating cell built with Letts. The Cravens–Letts collaboration reported cells producing an average of roughly 7 watts of excess thermal power over sustained periods. These claims of excess heat have not been independently reproduced to the satisfaction of the mainstream scientific community, which does not accept cold fusion as an established phenomenon.
Cravens has also proposed the HOPE (Hydrogen Originated Plasma Energy) concept, an engineering project for a long-range hybrid vehicle intended to combine a solar array, hydrogen generated from the reaction of recycled aluminium and water, and heat from a submerged deuterium reaction.
