Lossless Transmission Through NANOTUBES
[attachment=27798]
Introduction
The nascent field of nanotechnology is attracting increasing attention from electrical engineers. The field of nanotechnology, which at this point is really only nanoscience, has only recently gained legitimacy.
All signs indicate, however, that it is poised for robust growth during the coming decade. One of the problems with this subject, however, is that there is little agreement on what constitutes “nanotechnology.”
Some (including Intel) refer to nanotechnology as any technology that utilizes components smaller than 100 nanometers. Others have more radical visions of nanotechnology. These proponents foresee molecular assemblers building computers that are millions of times faster than current computers.
If Moore's Law is to have any chance of continuing past 2010, electrical engineers will need to continue to make rapid progress in molecular nanotechnology.
Carbon
Carbon atoms are among the more common substances in the universe. They are found in air, the sea, in all organic substances and form the second most abundant matter in the human body.
They are found in all forms and have a colourful array of properties. A perfect example is the difference between graphite and diamond. Both these substances are made of pure carbon but have no properties in common other than their state.
The reason for its versatility is due to its bonding capabilities. Carbon atoms are able to form covalent bonds with many other atoms.
A covalent bond is a form of chemical bonding characterized by the sharing of electrons between atoms (The other form of bonding is known as ionic bonding). Carbon can form up to four covalent bonds which is more than most other atoms can form.
Also there is no other element that bonds as strongly to itself and in as many ways as the carbon atom, thus explaining the extraordinary strength of diamond.
Graphene model
Graphene is an allotrope of carbon. Its structure is one-atom-thick planar sheets of sp2-bonded carbon atoms that are densely packed in a honeycomb crystal lattice
Graphene differs from most conventional three-dimensional materials. Intrinsic graphene is asemi-metal or zero-gap semiconductor.
Conclusion
The application of carbon nanotubes in power transmission can provide vast improvements to todays means, as in all other fields.
Not only will transmission lines be greatly improved, but also the loads will be more efficient and consume less electrical energy.
Appliances will be longer lasting and less faulty prone.
Nanotubes are miniscule particles that are not easy to control nor produce.
There are certain methods that are in use to create them, like high-pressure carbon monoxide deposition or chemical-vapor deposition, yet this is far from enough to satisfy global needs.
For now nanotubes are a dream, but are in the making; and one could argue that a breakthrough might be just around the corner.
