HAMPTON, Va. — Store and hotel employees and guests may one day be protected from harmful carbon monoxide fumes, not just be alerted of its presence. That is, if the new NASA invention gets to the marketplace. The device (pictured above) created at the Langley Research Center in Virginia, uses a low-temperature oxidation catalyst to convert toxic carbon monoxide to innocuous carbon dioxide, a standard gas that is breathed and exhaled. The new breed of catalysts also removes toxic formaldehyde from air.

Although it cannot be seen or smelled, carbon monoxide can kill within minutes. The Environmental Protection Agency observes, “Hundreds of people die accidentally every year from CO poisoning caused by malfunctioning or improperly used fuel-burning appliances.” It goes on to warn, “Fetuses, infants, elderly people, and people with anemia or with a history of heart or respiratory disease can be especially susceptible.”

Various states often have laws mandating the installation of carbon monoxide detectors in homes.  Some states also require detection devices be installed in restaurants, hotels and other business establishments.

The new catalysts were initially developed by NASA scientists for research involving carbon dioxide lasers.
