I work at CERN. We work on a cooling system that has found uses on satellites and also the International Space Station. Now, it would be wrong to say that CERN invented this. More that there was sufficient need at both CERN and in satellites for such a cooling system. Does it have a use beyond High Energy Physics? I'd like to think yes. It is impressively stable, thermally speaking.

Another example is a colleague working on lasers with crazy narrow beams.
