China considers the barrel method in high seas, high technology: Just don't import it. They pretty much have us over a barrel, especially if we keep sending our E-waste to them, rather than recycling, reclaiming the rare earth elements therein.
I guess we could go with finding some island and using geothermal to power the lab, scrape the cooling lava, see if it has any rare earth elements therein.
Figure if we're using geothermal to power the lab, then we don't have to worry about the inefficient use of resources if we're making rare earth elements less rare. If we really get into trouble, we could always try making them on the moon, where getting/ making energy (power) isn't a problem.
Or subs, we could always hook up a submarine lab to a crevice in the ocean floor that's releasing all kinds of gases and geothermal power. Heck, we could use the crushing depths to create energy.
So, you know, we'll be okay. Personally? I'm hoping diplomacy wins the day.
