There is supposed to be some kind of standard where a Patent should allow a competent practitioner to follow the patent and repeat what was done. This is not the cast with this patent. Someone trying to follow this would still have a lot of guessing as to what to do to attempt to make it work.
An apparatus for heating fluid includes a tank for holding fluid to be heated, and a fuel wafer in fluid communication with the fluid. The fuel wafer includes a fuel mixture including reagents and a catalyst, and an electrical resistor or other heat source in thermal communication with the fuel mixture and the catalyst.
The powder in the fuel mixture consists largely of spherical particles having diameters in the nanometer to micrometer range, for example between 1 nanometer and 100 micrometers. Variations in the ratio of reactants and catalyst tend to govern reaction rate and are not critical. However, it has been found that a suitable mixture would include a starting mixture of 50% nickel, 20% lithium, and 30% LAH. Within this mixture, nickel acts as a catalyst for the reaction, and is not itself a reagent. While nickel is particularly useful because of its relative abundance, its function can also be carried out by other elements in column 10 of the periodic table, such as platinum or palladium.
The nickel powder must be pre-heated to convert trapped water into supercritical steam, explode, and increase the porosity of the nickel. The concept of enhancing the porosity of the nickel is mentioned multiple times. Perhaps the enhanced surface area and tubercules of carbonyl nickel provide a good starting powder that is improved by pre-heating. It should also be noted that the most successful replicator of this technology, Alexander Parkhomov, who has successfully produced excess heat in at least a dozen different tests, recently revealed to the Martin Fleischman Memorial Project that he pre-heats his nickel to 200C to remove any water content
