A woodworking clamp with a handle in line with the screw will generate about 400lbs of force. That’s a reasonable model for how much axial force you will be able to exert with a screwdriver handle and beefy threaded screws. To get 150000 psi you have to squeeze something .0027 square inches, or 1.7mm^2, leave some room for edges and let’s work with 1mm^2.
I’m not sure what interesting things can be done with this superconductor in 1mm^2, but squeezing the anvil isn’t outrageous.
For perspective, TSMC will put 150 million transistors in that area. I kind of suspect that integrated circuits might flow at this pressure, so that might not be the application, but a superconducting ground plane and power plane would be interesting.
Edit: Wait, maybe that’s just a giant capacitive load on all the signals. Do something smarter.
- thfuran 4y agoNever mind the silicon, that's about at the compressive strength of tool steel and significantly more than that of stainless.
- jws 4y agoI'm beyond my expertise, but silicon crystal's compressive strength is 3GPa, so maybe? Plus I assume one would surround everything with a "fluid" (or at least flows at that pressure) to distribute the forces. Silicon chip fluid suspended inside carbide anvil with a steel clamping structure and tightening bolts should work. Interconnects are left as an exercise for the reader. I have enough faith that this would work out that I'd put it in a sci-fi story, and not enough that I would invest in a startup.
