Care to name a few specifically from Genini and Apollo?

And BTW, 99.9% of the materials used is aluminum.

Maybe I'm imagining too far back. What I'm getting at is that a lot of stuff
we use on Earth came out of developments intended for, and used in, space. I
think semicinductors in future will follow a similar path. To what extent I
have no idea, but I think it likely. So again, I say that the use OUTside a
space vehicle is no great leap once they're already inside one.

It WAS transistor development that was pushed by the space race as tubes
are very heavy in comparison and use lots of power.

One more time, we already know EXACTLY how an antenna made of a superconductor
would work, both on Earth and in space.
