We all know about Nano tubes and how they are to be the new wonder material ushering in new and wild possibilities
well ...now we have another company that has solved the manufacturing process...

NCTI’s patent pending processes change the game. We have developed methods to continuously produce very long, pure, carbon nanotubes, in the millimeter range of length, at high growth rates. Longer nanotubes mean greater strength, higher conductivity, easier handling, and greater product safety. They are key to providing the attractive properties exhibited by individual tubes.
"Widespread industrial use of carbon nanotubes has also been limited due to a lack of volume production methods to create long nanotube fibers or sheets, with attractive physical properties, for use in final products.
To address this, NCTI has also developed novel methods to fabricate its nanotubes into structurally strong and electro-thermally conductive fibers, yarns, and sheets. They are delivering on some of the long awaited promises of carbon nanotubes. For example our products exhibit:
High Strength – our spun conductive yarns exhibit breaking strengths up to 3 GPa expressed or in other terms: 1.5 Nt/Tex or 450,000 psi and with fracture toughness that is higher than aramids (such as Kevlar® or Twaron®). Our CNT sheets have breaking strengths, without binders, that range from 500 MPa to 1.2 GPa depending upon tube orientation. Aluminum breaks at 500 MPa, carbon steel breaks around 1 GPa.
Electrical Conductivity – Capable of carrying more current than copper and are also more conductive than copper at high frequencies.
Thermal Conductivity - Capability to transfer more heat than copper or silver on a
per weight basis.
Thermoelectric behavior - Demonstrate a Seebeck coefficient of greater than 60 µV/ºK
and power greater than 1 watt/gram.
Extremely Lightweight – Less than half the weight of aluminum "
