This is a photo of a technician at KES Science and Technology Inc., in Kernesaw, Georgia, assembling the AiroCide Ti02, an anthrax-killing device about the size of a small coffee table. The anthrax-killing air scrubber, AiroCide Ti02, is a tabletop-size metal box that bolts to office ceilings or walls. Its fans draw in airborne spores and airflow forces them through a maze of tubes. Inside, hydroxyl radicals (OH-) attack and kill pathogens. Most remaining spores are destroyed by high-energy ultraviolet photons. Building miniature greenhouses for experiments on the International Space Station has led to the invention of this device that annihilates anthrax, a bacteria that can be deadly when inhaled. The research enabling the invention started at the University of Wisconsin's (Madison) Center for Space Automation and Robotics (WCSAR), one of 17 NASA Commercial Space Centers. A special coating technology used in this anthrax-killing invention is also being used inside WCSAR-built plant growth units on the International Space Station. This commercial research is managed by the Space Product Development Program at the Marshall Space Flight Center.
