We just need to use it in smart ways We’re more likely to get copper from asteroids first before using our resources wisely
Comment on Geologists doubt Earth has the amount of copper needed to develop the entire world

Copper doesn’t get used up. The blue rocks in the picture are basically copper rust. We just need to use it in smart ways…no copper pots or door handles. Or at Least identify and recycle it more efficiently by returning used electronics to the stores we purchased them from. Those places should have a plan on how to dismantle the used electronics and how to reuse the materials.

Didn’t China just punt off a ticket to some asteroids? Viability tests maybe?

Copper pots and door handles are very smart products as copper has killing bacterias properties, it is self cleaning, in some way.

Its possible to just coat the surface if that’s the effect needed. I was so happy a year ago that I had found copper Ethernet wire. However upon inspection recently the wire is basically aluminum coated in copper. Usually, platers will first clean the surface and then electro less coat nickel on aluminum. Then you can coat other things like copper. Aluminum forms an oxide almost instantly in normal atmosphere so its difficult to coat with anything. But electroless nickel works very well after an HCl bath or a nitric bath.
