Heat-Detecting Sensor May Be Able to Detect Lying
used to pluck out terrorists or other criminals from crowds. The researchers, led by James Levine, of the Mayo Clinic in Rochester, Minnesota, tested the heat-sensing lie detector by having some test subjects commit a mock crime—in this case stabbing a mannequin ...
Passive Solar Design Guidelines
For example, a basic passive cooling strategy is to permit cooler night air to ventilate a house and cool down the thermal mass (this can be brick, stone, or concrete walls or floors, or large water containers) inside the house. The thermal mass will absorb...
