Elemental silver SD card casing for maximum thermal transfer, when????

What an age we live in

But there's no better way to make a really traditional dioxin omelette.

"Honey, I accidently digested our SD card again"

True enough. Though I wonder, as a thought experiment, what would be the actual better option in the long run. Some type of resin maybe?

Good thing heavy metal toxicity isn't a problem.

You're not supposed to eat them.

at least its not a single use product, the packaging it comes in is probably a worse contributor

But what about ingesting micrometals

True wireless charging would definitely, the kind where your phone being in the mere vicinity of the "base station" allows it to start charging. From an actual distance larger than a handful of centimeters. That would be a feature worthy of the sacrifice of a metal body and being stuck with glass

The "Wireless" charging marketing gimmick is just as bad as the "Hoverboard" gimmick vs a real Hoverboard a la Back to the Future.

Its basically just a plug shifted from a socket to the back of the phone, but worse. It's almost always slower and saves a second or 2 at most from having to plug/unplug it. Some minor pros, but not worth having to be saddled with annoying and fragile glass backs. You still need to take it out of your pocket, place it in a designated spot, and can't use it all that well while in the designated spot and still have it charge.

It's a gimmick so companies could say their phones totally have wireless charging so they didn't have to spend the R&D money to develop actual wireless charging and you bought into it hook, line and sinker.

There were some promising developments on real wireless charging, but ever since the fake gimmick caught hold it's been awfully quiet. Another victim of marketing I suppose.

In a sustainable world, energy can and should be cheaper than raw materials. We are only harvesting a tiny fraction of the solar energy hitting the earth, to say nothing of wind and geothermal power. Rolling out more renewables and energy storage and using some of the surplus power to switch from extracting new resources to recycling our waste would greatly lower our footprint.

But compared to plastic from virgin fossil fuels?

We as a society are going to need memory cards.

What do you think they should be made out of?

An SD card lasts for years, and the amount of plastic in one is negligible. It’s just not an issue.

Hark! The ghosts of countless generations of short-sighted polluters cry out in complacent, rationalizing unison!

It's not about expecting one model of memory card to save the Earth. It's about moving away from needless production of toxic materials, everywhere.

And if you don't care, nobody's going to force you to read The Lorax, but please don't go around shitting on people's appreciation for even the small things.

Any reduction in plastic is a good thing.

Aluminium is a better conductor than copper by weight, but not cross sectional area. It's used in aerial conductors because the weight is more important than the diameter. And it's cheaper.

it’s called CCA for what should be fairly obvious reasons.

CCA Ethernet cables are literally the worst. The wires are much more brittle so it's much easier to break the cable just by bending it a little bit, and since the resistance is significantly higher, they can't go as far as regular pure copper cables, and you can't use them for Power over Ethernet (they'll overheat).

People buy them to save money since they can be a lot cheaper, but often end up having to re-run a lot of the cables in the future. Better to just buy the high quality cables from the beginning. "Buy once, cry once" as the saying goes.

Sure, aluminum as the sole conductor is rare, but as you said, there is CCA, which is ridiculously common. CCA is mostly aluminum to save cost but is still 60ish% as conductive as copper.
