A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

This has so many errors. Copper is a far better conductor than people. Set up a multimeter for resistance across your skin if you're dubious, it'll be in the kΩ per cm. Current will flow if a potential difference is present, regardless of whether there is a less resistive path available. Also the material in question is a metal oxide, not a metal. It's brittle. So making it into a cable in the first place will be incredibly difficult and expensive. And even in their own paper they showed a limiting current of something like 400 mA, which is not suitable for high power applications.
