Check this. Carbon nanotubes being used to make bulletproof material.
Nanocomp Technologies, is the first in the world to make sheets of carbon nanotubes — microscopic tubes stronger than steel but lighter than plastic. The Pentagon has financed much of the Concord, N.H., firm’s work; stakes include the $500 million U.S. market for body and vehicle armor, which is currently dominated by DuPont’s Kevlar.
In April, [Nanocomp’s owner, David] Lashmore had a mechanical multicaliber gun shoot bullets at different versions of his sheet, each less than a fifth of an inch thick, at a speed of 1,400 feet per second. Four sheets were breached, but three showed no damage. Lashmore and his 35 employees were ecstatic.

Army tests show the material works as well as Kevlar. The military also hopes to replace copper wiring in planes and satellites with highly conductive nanotubes, saving millions of dollars in fuel costs.
It’s interesting. Lashmore was able to grow nanotubes large enough to make into yarn and sheets, and from there they can do whatever. Gotta wait to see where this is going to go.
Stuff From Hsoi 
Dude. A conductive bulletproof vest has way too many exciting application possibilities. And while an inch-thick body armor is still going to be heavy, cumbersome, and hot, it is a hell of a lot better than we have now, and even a single sheet of it might provide adequate protection for some things… Shiny.
And not just body armor, but how this can be used in vehicles.
Amazing possibilities here.
Very interesting indeed! The broader applications that might come about could prove to be one of the greatest technological discoveries in decades.
Actually it does make me wonder about non-military applications.
For instance, in my motorcycle riding I’ve got a set of Draggin’ Jeans:

which is using Kevlar.
Then there’s stuff like Esquad Jeans and Armalith fabric:

which is really really cool.
So.. could this stuff be used say in motorcycle armor? I guess it would depend upon how well it can handle abrasion.
