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).
