> But how many of these actually practical and useful things were invented by NASA? https://en.wikipedia.org/wiki/NASA_spinoff_technologies https://en.wikipedia.org/wiki/NASA_spinoff_technologies > I would assume in many case the issue was that some technology existed but it was expensive and difficult to deploy at scale which is not exactly what NASA was trying to solve.. In many cases yes, they didn't invent the technology per se. But in those cases they improved or refined the tech and by virtue of being a public agency released the information freely for public use.
