There's a cosmic rays detector that I was in charge of, even if I have little idea how it works. Apparently, it requires some very toxic gas (I have forgotten its name... something with -fluor- in it maybe?) that has since become forbidden from shipping. So there are a few spares remaining on the island (forbidden from shipping away anyway) but no legal way to keep operating once they are used up.
