November 18, 2003: Combat zones are excellent places to test new technologies,
especially if these experimental items will save lives. One example is a
lightweight armored turret for Humvee vehicles in Iraq. Because of its light
weight construction, you cannot put a turret on a Humvee that weighs more than
400 pounds. Armor, even Kevlar fiber armor, can only provide so much
protection within the 400 pound limit. But an experimental (meaning very
expensive to manufacture) nanotech armor was used to construct a 200 pound
armor turret that can stop 12.7mm (.50 caliber) bullets. The fiber uses
nanotecholgy (where magnetism or other forces create customized molecules with
special properties.) The nanofiber in the Humvee turrets looks like
fiberboard, but it is 17 times stronger than Kevlar (which is itself six times
stronger than steel). However, it's going to be several years before the cost
of the new fiber gets anywhere near Kevlar's levels (about $50 per square yard
of fiber).
