URSpider writes "CNN and the BBC are reporting on a US military test of a new antipersonnel heat ray. The weapon focuses non-lethal millimeter-wave radiation onto humans, raising their skin surface temperature to an uncomfortable 130 F. The goal is to make the targets drop any weapons and flee the scene. The device was apparently tested on two soldiers and a group of ten reporters, which makes me wonder how thoroughly this thing has been safety tested. The government is also appealing to the scientific community for help in creating another innovative military technology: artificial 'black ice'. They hope to deploy the 'ice' in chase scenarios to slow fleeing vehicles." We discussed the military's certification to use the device last month.
