If you aren't interested in science or engineering calculations, in other words, if you are interested in science and technology period, feel free to start a thread on your last Harlequin Romance Novel.

From: Bret Cahill on 31 Jan 2010 14:48 Instead of oriented fibers particles of any shape and orientation could be designed to shatter like tempered glass at the force profile typical of an adult human wearing a boot. When a lot of particles seem to be thinning out they might want to send a drone over. Some large animals in some situations may still give occasional false positives but the military would soon be able to distinguish between what "looked like" a herd of cattle grazing and what looked like Al Qaeda moving single file along a path in to ambush a remote outpost. A four legged beast can handle rough terrain much better than most humans and will disturb / destroy the particles differently. Bad weather isn't going to change the fact that sooner or later the Taliban will have to leave their caves and crush some particles. Some particles can be designed to reflect over different wave length ranges to date when they were dropped. A single area could be crop dusted several times at different dates to produce a record of activity.

This thread is for those interested in some _numbers_ on the deployment of a satellite based laser system that tracks terrorists hiding in caves by crop dusting large regions with reflectors. If you are a moronic high school drop out rightard who flunked math feel free to start a thread on some other issue, i.e. Harliquin Romance novels or whatever girly books you read. Bret Cahill

Now if you want to discuss the cost of plastic micro reflectors, post here. If you don't then start a thread on Glen Beck or Harliquin romance novels or whatever gets you wee weed up. Bret Cahill
