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.

National Instruments signs to do E-Cat controls
all of the instrumentation for the E-Cat cold fusion plants, which began to be sold commercially on October 28 with the first 1 MW plant successfully tested in Bologna.

The 1 MW plant, which is the size of a small shipping container,Coach Factory Outlet, and said to produce about as much power as a small locomotive, is made up of around 100 modules, each containing three reactors acting in parallel that combine hydrogen and nickel (a special micro powder preparation) into copper in the presence of a proprietary catalyst and a radio frequency stimulator, beginning at around 450 degrees Celsius. The initial heating is supplied electrically from resistive heaters. Once the nuclear reactions commence,Coach Factory Online, the start-up electrical energy source can be disconnected,http://www.coachoutletfactory-sale.com/, and the self-sustaining reaction can be controlled by the amount of hydrogen pressure supplied to the chamber.

The first one-off e-cat plants cost 2,000 Euros per kilowatt,Coach Outlet, or 2 million for the 1 MW plant. But once mass produced,www.coachoutletfactory-sale.com, Rossi expects the cost to go down to 100 Euros per kilowatt installed -- a tenth of what coal or natural gas power plants costs, minus the fuel costs.

Joseph Friedlander had a brainstorm on how to launch the Wang Bullet (project Orion pulsed propulsion variant) from under the sea. —build at the bottom a giant shell,http://www.coachoutletfactory-sale.com/, from components lowered into place, layer by layer enclosing its internal payloads with external structures (such as a supporting sabot) and sealing the unit to flight-ready status. Place sets of guide rails around the perimeter of the shaft with ‘slippers’—metal contact shoes—touching the rails from the edges of the Wang Bullet. Finally, after all is in readiness, pump reaction mass through an access shaft under the sabot into a prepared chamber and place a thermonuclear explosive device in the midst of the reaction mass.
The reaction mass (in our conceptual model, water, but many other substances would work) not only becomes the propulsive hypersonic plasma and impulsive gas but also serves as an accelerative, radiation (boron included against neutron flux) and impact shield relative to the extreme violence of the blast chamber. So it is not the nuclear blast that directly accelerates. The blast acts on the propellant and filler.

Nuclear Verne BlowGun - the entire system,Coach Outlet, the hole, the nuclear device, the cistern of propellant and the projectile
Wang Bullet - the projectile being launched
Friedlander Sabot - the base of the projectile
One of the biggest objections to the nuclear cannon concept has to be the idea of a radioactive hole left behind. It is an emotional feeling.
Suppose the launch tube and setup at sea costs $75 million, and the Wang Bullet and thermonuclear device all together,www.coachoutletfactory-sale.com, including launch and payload costs $200 million. That is less than a shuttle launch. But instead of 15 tons to orbit (the equivalent of 3 tons to the Moon) we are talking probably 1000 tons to the Moon. That is $200000 a ton to the Moon, or $100 a pound. The benefit would remain very low cost to launch material and payloads that are resistant to high G forces and no radiation in the atmosphere and no radiation in the ground. The sea would disperse the radiation from the underwater explosion. The underwater explosion will make it easier to prevent radiation from getting to the atmosphere.
* Nuclear bombs exist and there is no question that they work and there are thousands that have built,Coach Factory Outlet, paid for and in storage
* There were tests which showed that nuclear bombs can launch heavy metal objects at high speed and the objects survive
* The system is taking material and using a nuclear bomb to provide the energy to make it into more energetic propellent. Chemical propellant maxes out at lower speed and energies. Nuclear take the same chemicals and ups the heat (100 million degrees instead of a few thousand) for more speed and energy
* the Ocean already contains 3.5 billion tons of Uranium
The current space capability versus the proposed system is the difference between starting a colony and industry with the supplies you can put in a pickup truck or what you can put into a container ship.
Nuclear effects would not get into the air, what will be in the water is safe,Coach Factory Online, hundreds of times more supplies at one hundred times lower cost for space using technology that exists.
