12. Airplane winglets

In the mid-1970s, as part of their Aircraft Energy Efficiency program, NASA began experimenting with winglets — vertical tips placed at the end of aircraft wings — to help reduce drag. Winglets are now ubiquitous on commercial jets and help increase fuel efficiency and reduce carbon dioxide emissions.

13. Invisible braces

After NASA and Ceradyne researchers discovered that polycrystalline alumina can protect radar equipment without blocking the radar’s signal as it tracks heat-seeking missiles, Unitek Corporation/3M teamed up with Ceradyne, using the material to invent invisible braces for teeth.
