It doesn't seem to be a gas, so applying pressure would be as easy as tightening the enclosure, like fastening a bolt. Cables could be made by just sticking a superconducting core inside a compression sleeve, although they'd probably have to be segmented, and breaking the sleeve in any place could make the core stop superconducting and overheat pretty fast. Other than that, it should be perfectly safe.
- lvh 7y agoThe values suggested are north of the ultimate tensile strength for carbon nanotubes and graphene. It’s in the ballpark of the center of the earth. I don’t think it’s as simple as tightening a bolt.
- saalweachter 7y agoHell, I'd even call it "not incomparable to the pressure at the center of the Sun". I mean, it's still like ~100x smaller than the smallest estimates, but it's also only 100x less pressure than is plausibly at the center of the Sun.
