From: Axil Axil * There have been reports that Rossi uses big micro grain sized particles as a lattice support structure to buttress small nano-dimensioned tubule structures of nickel. This more complex topology would cut down some on the maximum surface area that would be provided by a single tiered uniform nano particle topology. It doesn't seem likely that the "tubules" themselves are actually composed of nickel, although it is possible. But whatever they are composed of - they would serve the purpose of 'ventilation' of a lattice-like structure, as you indicate. Someone (maybe it was you) had speculated before that the tubules could be carbon nanotubes, or titania nanotubes - both of which are commercially available.
These nanotubes could be simply mixed in with a larger grain size of "loaded" micro-particle which has nano-islands, in order to facilitate migration or circulation of hydrogen deeper into and around the powder. That makes a fair amount of sense based on conflicting statements from Rossi. It also makes sense as an alternative - to provide circulation of hydrogen in a way similar to Thermacore was doing with porous nickel capillary tubing. But instead of having the reaction occur on the capillaries themselves add the nanopowder and catalyst as a mix. Either way, it would seem that the reactor must provide a way for hydrogen to circulate and contact as much surface area as possible, when large particles are being used. Using PWM to pulse the heat input would essentially "pump" hydrogen as well. Rossi gives every indication of being well-read and aware of what is in the LENR literature. If he missed the Thermacore papers (there are a least three of them out there, two on gas phase and one electrolytic) then that would be a bigger surprise than if he was able to modify the technique and improve it by using carbon nanotubes instead of nickel capillary tubes.
