Nanotube Applications Grow And Grow 264
HobbySpacer writes "Carbon nanotubes are starting to transition from interesting laboratory curiosities into interesting technological applications. These apps include non-volatile RAM, flat screen displays, high strength fabrics, and smart skin for structures in aerospace and elsewhere. Perhaps if The Graduate was being made today, the one word for Benjamin Braddock's future would not be "plastics" but "nanotubes"."

Uh, what do you think plastic is made out of? The core of what most people think of as plastic (as opposed to the technical definition which focuses on properties rather then composition) is based on a chain of hydrocarbons [handsonplastics.com], with some impurities.
In fact, what most people call "plastic" are closer to "natural" things then nanotubes; no "natural" lifeform consists of pure carbon, so a carbon + hydrogen mix is closer.

That's all fine and dandy, but a bullet proof piece of clothing 'as light as a t-shirt' wouldn't so squat. Kevlar is a pretty light material too, the reason bullet proof vests are so heavy is because of the large impact absorbing plates. Without some impact absorbance, the bullet would just end up dragging a whole bunch of cloth into the gaping hole in your chest. You have to have something to absorb the kinetic energy; and a t-shirt just doesn't cut it.
