This kind of development makes us realize that removing safety hazards is far better than creating alarms to detect them.
Spinoff technology can help to make our homes and communities safer and more comfortable places to live. Most people are aware that carbon monoxide (CO) buildup in our homes can be very dangerous. This may come from a faulty furnace or fireplace. ( ① ) Consequently, some people have carbon monoxide detectors in their homes, but these detectors only alert them if the level of carbon monoxide is unsafe. ( ② ) However, using space technology, NASA developed an air-conditioning system that can not only detect dangerous amounts of carbon monoxide, but actually oxidizes the toxic gases into harmless carbon dioxide. ( ③ ) In addition to helping people to have clean air, having access to clean water is also of major importance for everyone. NASA engineers have been working with private companies to create better systems for clean, drinkable water for astronauts in space. ( ④ ) These systems, which have been developed for the astronauts, can quickly and affordably cleanse any available water. This is a major advantage to the people on Earth who live in remote or developing areas where water is scarce or polluted.
