[quote="Santoslhelpa"]ions repel each other
when you pack the ion up i s u s p e c t that this problem gets solved or eased... [quote]
You are confused by the scale of things. A carbon bucky tube is a large molecule, and the structure is dependant on the electrons that form covalent bonds. These electron will shield the repelling charge of an approaching positive ion, but only until the ion passes the electron shells on it's way towards the nucleus of the atom. Then the ion sees the entire repulsive force of the target nucleus. It has to be traveling fast enough to have a small chance of reaching this tiny target inside the relatively huge electron confined space. In other words almost all of the significant action occurs at distances mush smaller than the electron orbitals around the nucleus. The atomic scales are too big, any molecules made up of atoms have even larger scales. Even having a soup of plasma with excess electrons doesn't effect the process much (if at all) There are quantum mechanical reasons why an electron will only come so close to a proton when it is orbiting it. A muon gets much closer because of it's increased mass, and it is this shorter distance that allows it to indeed provide significant shielding. For fusion to occur the approaching nucleus has to get close enough for the strong nuclear force to overwhelm the coulumb repulsive force.
Look up representations of of atoms. The nucleus is ridiculously smaller than the cloud of electrons that orbits it, and the size at which the strong nuclear force becomes dominate is also tiny compared to even the tightest electron orbits.
All that being said, cold fusion that does not involve muons (if real) confuses the issue.
