Bob, Yes glassy iron is cheaper and Glassimetal, Inc also has an iron based product on their site, presumably available now. The glassy iron could possibly catalyze H2 to dense hydrogen more efficiently.
The advantage of extreme physical strength against deformation - for cold fusion - is that if the metal lattice is strong enough then hydrogen will experience ultra hugh pressure without damaging the containment. If that could happen reliably, then for deuterium fusion to occur - a localized Lawson criterion is applicable and essentially you have true thermonuclear fusion based on substituting high density for lesser heat in a transient state. I find it interesting that Apple is apparently funding much of the work via CalTech. It is not clear what their specific interest is but they are overdue for a major announcement, rumor has it. AFAIK - Apple has never done anything in LENR, but obviously they have a huge interest in smaller power supplies and batteries. Years ago, Randell Mills was promoting a battery concept where hydrino-hydride was to be the charge carrier. That concept went nowhere but the idea lingers, and Mills may have been way ahead of its time. bobcook39...@hotmail.com <bobcook39...@hotmail.com> wrote: A cheaper glassy metallic has been developed—see the abstract below: Fe‐based Metallic Glasses in Functional Catalytic Applications https://doi.org/10.1002/asia.201801082
