I have been pondering on this for quite a while. Suppose a wire made hollow with nanotechnology; the hollow area would be vacuum with occasional electrons from the conductor. Now the wire is covered by a negatively charged insulator; will the electrons be forced into the vacuum space, being repulsed by the negative charge? And if the electron was forced into the vacuum space, there will be less collisions; so will the electrons achieve higher speed than conventional wires when conducting electricity? A crude diagram to explain my point-   |

Interesting idea! It seems to me that electric waves should propagate more quickly by the free electrons electrically confined in a vacuum. The conductor layer would have to be thinner than it's skin-depth. This would be easy enough, due to the charge skin lying inside the conductor instead of on it's surface. I do wonder why you wouldn't just get rid of the conductor altogether?

Well, the picture ain't quite perfect; didn't mean to make it that thick... And I couldn't think of any source of electron other than a conductor. Can you think up of any other source? I think it would be too much hassle to totally separate electrons from the atom/molecule it is originally from... Might make the product too expensive with all the nanotechnology and all. |

You could perhaps have an Anode attached to one end of the tube, and a Cathode on the other. Anyway it's a cool idea.

Yeah... that would work, but what about AC...? I am not really much knowledgeable in physics (just a high school graduate this year). And if vacuum wire were to be used, then the negativity of the charged insulator should be controlled. If it would be too much electrons from opposite directions could collide & result in a higher resistance all over again; if it's too less, the electrons would still still stick to the conductors... My idea is too complicated than I thought it would be... >.< |

It is a very interesting idea and I beleive it could work, the conductor should be gotten rid of. However, I don't think it would be very practical unless one really values speed over efficientcy. The electrons will not easily go into a negatively charges tube and it will take more energy to force them in. IS THE SPEED OF LIGHTNING NOT FAST ENOUGH FOR YOU PEOPLE? |

You are mistaken. Electricity does not travel at the speed of lightning through the wire because of resistance, thus I came up with this idea. And about forcing electrons in a negatively charged tube, a theoretical equation could be developed to calculate the area of space affected with negative force as per the value of negativity applied on the tube. If this is possible, then we can easily have the centre of the tube without negative force, thus allowing electrons to travel unaffected. |

I know resistance changes the speed of electrons, that was a joke pointing out that things already work faster than people could even dream of in the past. Anyway, a magnetic force works just like gravity, there is no point that is stops it only gets weaker. Secondly, electrons themselves are negatively charged so, even if you did creat a space with no negative force, the electrons themselves would make it hard to force more elecrons in. MY ONLY PROBLEM IS THE EFFORT NEEDED TO GET THE ELECTRONS IN THE TUBE. |

That's exactly why we need to calculate precisely the amount of negative force applied for every different width of tube. To minimize the effort required & allow the electrons to move as efficiently as possible. |
