First fracking now large amounts of electricity to be pumped underground too!

Gotta get that 5g out

Humanity was not responsible enough with bitcoin to learn how to turn electricity into actual gold. Some nerds going to start setting up Tesla coils in caves soon.

[–] Zorsith@lemmy.blahaj.zone 8 points 2 years ago (1 children)

I mean... actual gold isn't crazy valuable these days, is it? It's used in quite a bit of electronics for its corrosion resistance and conductivity IIRC.

[–] jmiller@lemm.ee 18 points 2 years ago (3 children)

Gold prices have risen steadily for a long time, partly because of its use in electronics. Over $2500/ounce now. But another quirk of gold is the ease with which we can make very thin coatings of it over other materials, sometimes only a few atoms thick. So it is commonly used, but in very very small amounts per device.

[–] Zorsith@lemmy.blahaj.zone 4 points 2 years ago (1 children)

TIL. Electroplating is cool stuff

[–] chaogomu@lemmy.world 4 points 2 years ago (1 children)

The main reason to electroplate things in gold is that corrosion resistance.

The thinner the coating, the better. Mostly because gold isn't a very good conductor.

Copper is one of the best conductors available. But the corrosion is the problem. It's nonconductive.

Also a fun fact. Stainless steel is a better conductor than gold. But gold is slightly easier to use in electroplating.

I think you might want to do a little digging in your undergrad science books:

The units of electrical conductivity are measured in siemens per meter (S/m). Here’s the electrical conductivity of a few metals:

Stainless Steel: 1.0 - 1.5 × 10^6 S/m
Aluminum: 3.77 × 10^7 S/m
Copper: 5.96 × 10^7 S/m
Gold: 4.52 × 10^7 S/m
Silver: 6.30 × 10^7 S/m

In this list silver has the highest conductivity, and stainless steel the lowest conductivity.

Most of the gold's price comes from it being used in jewelry and as an investment. Less than 7% of gold is used by the tech industry

[–] jmiller@lemm.ee 3 points 2 years ago* (last edited 2 years ago)

Well, that is the amount gold that is mined or recycled every year that is used in electronics. The thing is though, a lot of the gold used in electronics is never recovered. So a considerable amount of the gold used in electronics is removed from from circulation in a way the gold in jewelry or bullion or coins isn't. It isn't the primary driver of gold's price increase, but it is a significant factor.

[–] Wanderer@lemm.ee 2 points 2 years ago (1 children)

If someone works out how to make gold cheap. Then the current value of all gold will collapse and there were be a huge supply of shit that's been covered in dust in a vault for 100 years.

[–] jmiller@lemm.ee 2 points 2 years ago (1 children)

Very true. Unfortunately, this process just pulls gold from dilute sources and gathers it into nuggets, from small ones to very very large. No gold is being made new though, that would be great.

[–] Wanderer@lemm.ee 2 points 2 years ago

There is a shit load of gold out their in minute concentrations

[–] shortwavesurfer@lemmy.zip 22 points 2 years ago (3 children)

Okay, for a second, I thought that somebody had figured out how to make gold in a lab, which would then obviously bring down the price dramatically, because it would no longer be a super precious metal.

[–] bluGill@fedia.io 24 points 2 years ago

We can make gold in a lab, it has been done. Let us just say there is a reason those who want $$$$ to build another super collider are not talking about making gold in them.

[–] SpaceNoodle@lemmy.world 14 points 2 years ago (1 children)

It's not gonna be like alchemy. Electroplating is already a thing.

[–] shortwavesurfer@lemmy.zip 12 points 2 years ago (1 children)

But damn it man, I wanted to turn a chunk of coal into gold LOL.

I didn't get the reference

[–] barsoap@lemm.ee 5 points 2 years ago (1 children)

We've known how to turn lead into gold for ages, you just add a couple of protons, neutrons, and electrons. Long story short: Uses a fuckton of energy, not worth it.

Fun fact: When Ernest Rutherford and colleagues put together the first paper about their findings they avoided the word "transmutation" like the plague. It has been considered impossible since before alchemy became chemistry and even though he was publishing in physics chemists would probably still have had his head.

[–] kerrypacker@lemmy.world 1 points 2 years ago (1 children)

Dumb question but would using nuclear energy make it more feasible?

[–] barsoap@lemm.ee 1 points 2 years ago

Nuclear energy is more expensive than renewable so not really, no. Having a good combination of starting materials to minimise the amount of energy you need to fuse everything together, or even starting out with something heavier, would be the way to go.

For more details ask a nuclear physicist of which I'm not one. Honestly there doesn't seem to be much work on it.

Libertarians about to get off on having gold mines in their garages.

[–] ivanafterall@lemmy.world 6 points 2 years ago

And you thought GPU crypto-mining farms were using a lot of electricity...

Gold prices after this 📉📉📉

[–] realharo@lemm.ee 3 points 2 years ago (1 children)

You still need the same amount of gold atoms at the input.
