Armchair quantum wire (AQW) will be a weave of metallic nanotubes that can carry electricity with negligible loss over long distances. It will be an ideal replacement for the nation's copper-based grid,Coach Outlet, which leaks electricity at an estimated 5 percent per 100 miles of transmission.
A prime technical hurdle in the development of this “miracle cable" is producing pure batches of armchair carbon nanotubes. Andrew Barron’s lab demonstrated a way to take small batches of individual nanotubes and make them dramatically longer. Ideally,www.coachoutletfactory-sale.com, long armchair nanotubes could be cut,http://www.coachoutletfactory-sale.com/, re-seeded with catalyst and re-grown indefinitely. Up to 90 percent of the nanotubes in a batch can now be amplified to significant lengths.

* Richard Smalley made the promise of a vision for a carbon nanotube electrical grid back in 1995.
* Smalley criticized the vision of mechanical nanotechnology as being scientifically impossible. However,Coach Factory Outlet, there has be experimental proof that molecules can be moved and made to react with atomic precision
* Despite tens of millions in funding Smalley and now 8 professors and labs that continue the work have not delivered one meter of commercial carbon nanotube cable after 16 years.
Let us say the current work allows some carbon nanotubes to be produced. The world production of carbon nanotubes is 1350 tons per year now. Armchair quantum wire is probably in milligram non-pure quantities now and the breakthrough may bump it up to semi-pure gram or kilogram quantities in 5 years.
About 1 million tons of copper is used for the global electrical grid. It has taken many decades to build out the worlds electrical grids. Even if carbon nanotube cables were 60 times less carbon nanotubes that would still be over a million tons of armchair carbon nanotubes.
Meanwhile ultra-high voltage lines save 30-40% of the energy losses and are deployed now. Superconductors are being deployed to
I think superconductors will be doing the job of making the electrical grid more efficient. I don't think rocking chair nanotubes will be able to get much market traction in 12-25 years. There would have to be massive production breakthroughs very much like the vision of molecular nanotechnology for the situation to change. Even then better molecular manufacturing would boost superconductors production and quality as well.
