The Car Bomb Finder from HiEnergy Technologies can be used remotely from a mobile command center to determine whether an explosive is present in the closed trunk of a car in 11 seconds without opening the trunk for a secondary inspection. This stoichiometric explosives detector works by deciphering the chemical formulas of substances. The technology also estimates the explosive’s weight and decodes quantitative empirical chemical formulas of any selected substance in 30 seconds. The company’s technology is now being used by the TSA to improve airport security.
