Nanotube Applications Grow And Grow

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"."

Without some impact absorbance, the bullet would just end up dragging a whole bunch of cloth into the gaping hole in your chest.

      See the hole in the plastercine? See the lack of tear in your cloth? You still need something to dissipate the energy concentrated at the point of the bullet over a wide area. Kevlar does not do that, nor would any material light and flexible enough to wear as a t-shirt no matter what it's made of.

      The very point of chainmail - even your average real kind - is to transform piercing/slashing damage into like bludgeoning damage. Without a really incredible amount of force, the spear would never pierce chainmail (not counting the pinning to the wall) and minimally cut the skin.

      The real fiction, however, is how Frodo manages to remain unharmed. The spear wouldn't pierce the flesh, but you're right in that the force wouldn't be dissipated. It would have probably broken every bone in his chest.

      Despite not actually stopping blows, chainmail was still a very good piece of armor. A broken arm is better than a severed one, and with deaths from disease so high in that era, you wanted to prevent all the exposed insides you could. Stopped arrows pretty well, too.
