also check that out. carbon nanotubes. we can isolate them. they are basically open, so magnetism and other waves can trespass. we could use some sort of shield to give the electrons a certain spin so they flow ordered or other things, but i have no sight on what's needed and what's possible. but what the scientists need is a machine which pulls the carbon nanotube strings so that it can be produced as cables.
