While I agree that it is an interesting finding, the lede of "at room temperatures" buries the fact that using a median of 330-360 gigapascals as a measure of the earths' internal pressure equates to a pressure of 8223639745.0093 pounds per square foot. (Rough calculations based on 3,300,000 to 3,600,000 atm for the Earths' inner core)
[Edit to correct the maths] = 5325785739.6251 pounds per square foot.
- handol 6y agoCouldn't the pinch effect be used to crush two superconducting filaments into each other? My rough calculation is something like 5 MA(in each conductor, spaced by 1mm) would do the trick, assuming that much current and B don't interfere with superconductivity (I have no idea). Looks like the highest current ever achieved is 100 kA. A mere 100 fold increase and we should be good to go.
