I know it wasn't mentioned in the original quote by Jim Voss, but
Teflon(tm) is often cited by the press and public as a spin-off from
space. In fact, Teflon(tm) was invented or discovered by a Dupont
engineer in 1938.

Discovered -- it was found by accident. However, it was a lab curiosity
then. What made it a practical engineering material was a big infusion of
government cash... not from spaceflight, but from the Manhattan Project.
