From: Axil the tubes should be solid because LENR is exclusively a surface reaction. To strengthen the tubes and provide a longer service life, the tubes may be filled with tough stuff like tungsten, for example,
It's probably a lot more complicated than that. Even Ed seems to be admitting now that there are several possible varieties of LENR :-) In the Rossi effect - LENR may not occur in tubes, and it doesn't need to. Or else, in Kevin's version it could happen inside tubes due to 1D condensation. The jury is still out on that point. However, even if CNT do not promote LENR by themselves (internally), they could still serve the secondary purpose of powering the light source, and SPP formation - by accelerating electrons which then produce radiation in the visible spectrum. Here is an interesting item that turned up. http://www.ece.umd.edu/~antonsen/Data/IRMMW-THz%202013/Extended%20Abstracts/ 2013-09-03-Tu/TU12-6.pdf It is not precisely on point for the Rossi effect, nor for the Cooper patent application, but there is a strong analogy for a complex mechanism which involves all of these factors below, operating together. 1) CNT which are hollow 2) SPP 3) Magnetic field alignment 4) Light source 5) Ni-H LENR (of some variety) to power all of the above and provide excess heat The idea is that the external light source starts the reaction, as in the Cooper patent, which is then self sustaining for a period, based on self-generated light (or alternatively IR photons from LENR heat). I wish we had actual data from Cooper (and Rossi) but it is understandable why this may not be forthcoming anytime soon.
