What would happen if you took a bundle of moderate length carbon nanotubes that are suspected of being capable of superconducting and place these within a strong magnetic field. The magnetic field would penetrate throughout most of the forest of CNTs. Now, give the structure a few whacks (hits) that cause some of the tubes to contact each other at both ends where before they were open circuited.
If some of the contacting tubes now form closed superconducting paths, they will trap the field within and become magnetic once the external field is removed. Perhaps this is a way to prove that they do indeed become superconductors at room temperature. I seem to recall someone using carbon black in an experiment that had them convinced that iron was formed because of the residual magnetic effects and wonder if something of the nature I mentioned is at work. This type of experiment should be tried especially if it demonstrates room temperature superconductivity of CNTs.

To check this we have exposed the virgin graphite powder to hydrogen plasma for 75 minutes at room temperature. The prepared powder shows the same characteristics as the water treated one indicating that hydrogen may play a role in this phenomenon.” I speculation on what is happening here as follows: The hydrogen is ionized into protons and these protons for cooper pairs. These pairs then form a condensate on the surface of the graphite grains that support superconducting current flow and associated magnetic behavior. A superconductive cable or rope might be formed using a bundling of carbon nanotubes inside a copper or aluminum tube that has been filled with hydrogen under pressure. Protons would fill the inside of the SWNT as a superconducting condensate. Checking this tube for room temperature superconductivity would be an interesting experiment to run.

This gives me some encouragement that I am proceeding in the right direction with my Carbon Nanohorn research. We know that carbon nanotubes, which are essentially graphene sheets, exhibit superconductive behavior at low temps. Further we know that these same carbon nanotubes exhibit ballistic conduction at higher temps even above room temps. Further, we know from research to use CNTs in hydrogen storage, that hydrogen ions/gas at certain conditions would dissociate and stick to carbon nanotube walls and hydrogenate and functionalize these CNTs. Further, we know that CNTs, especially SWNTs, exhibit long electron coherence lengths. Further, we also know that electrons will accumulate in CNT tips and promtoe field emissions. Further, we also know that electrons flowing on a CNT will charge screen ions that are within its charge screening radius (CNT diameter.) Further, we also know that CNTs will carry huge amounts of currents, more than what can be explained by simple electron flow theory - in metals. And finally, we know that superconductivity MAY be correlated to anomalous heat release. Therefore, I feel that CNTs are really the rgiht materials to serve as NAEs. One thing I found interesting was that the phenomena disappeared when they compressed the graphene powder. This indicates to me that this may have something to do with the destruction of the long filamentous graphene nanowhiskers that are associated with the phenomena. These filamentous whiskers appear to be critical to superconductive behaviour. This, of course, is what I think may be happening in my carbon nanotube theory. The phenomena these physicists found may be an LENR phenomena. Oh, I wished I can go back there to the states right now so that I can build my proof of concept reactor. But, in the mean time, finds like these are excellent. Thanks.

A method includes amplifying an energy release from a dispersion of nanoparticles containing a concentration of hydrogen/deuterium nuclei, the nanoparticles suspended in a dielectric medium in a presence of hydrogen/deuterium gas, wherein an energy input is provided by high voltage pulses between two electrodes embedded in the dispersion of nanoparticles. [...] Energetic reactions described fully herein are amplified by an inverse skin effect. These very small discharge pathways are so narrow that the magnetic fields close to them are amplified to magnitudes unachievable by other methods. Distributing nanoparticles in a dielectric (ceramic) matrix between two high voltage electrodes is a method according to the principles of the present invention for amplifying an energy output from the hydrated/deuterated metal nanoparticles in the dielectric matrix. High voltage pulses cause arc formations. The arc formations focus energy and the arc formations are channeled from one macroscopic grain to another macroscopic grain. Once a discharge is interior to a macroscopic grain the pulse is further focused into nanoparticles along the lowest impedance pathway. The arcs interior to the grains are where the energetic reactions are maximized. The nanoparticles provide a constellation of short circuiting elements for each current pulse. Each succeeding pulse finds a different pathway that minimizes the impedance between two electrodes. An overpressure of hydrogen is needed to prevent discharges from sliding over a surface of the macroscopic grains rather than through the grains and thereby through the hydrated nanoparticles. Low pressure hydrogen gas favors surface discharging. Liquid dielectrics produce similar energy focusing capabilities as the ceramic matrices. Liquid systems provide a direct method for producing nanoparticles in situ.
