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

Gold prices after this πππ
You still need the same amount of gold atoms at the input.
Gold prices after this πππ
Thatβs alchemy, not science in good faith.
Libertarians about to get off on having gold mines in their garages.
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.
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.
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.
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.
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.
There is a shit load of gold out their in minute concentrations
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

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.
TIL. Electroplating is cool stuff
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). Hereβs the electrical conductivity of a few metals:
Stainless Steel: 1.0 - 1.5 Γ 10^6 S/m
Aluminum: 3.77 Γ 10^7 S/m
Copper: 5.96 Γ 10^7 S/m
Gold: 4.52 Γ 10^7 S/m
Silver: 6.30 Γ 10^7 S/m
In this list silver has the highest conductivity, and stainless steel the lowest conductivity.
ancient alchemists popping off in their graves rn
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.
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.
Dumb question but would using nuclear energy make it more feasible?
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.
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.
It's not gonna be like alchemy. Electroplating is already a thing.
But damn it man, I wanted to turn a chunk of coal into gold LOL.
when youβre aΒ star, they let you do it
I didn't get the reference
slow clap
I'm feeling like a star. They can't stop my shine. I'm loving cloud nine my heads in the sky.
You, Sir, win the internet
First fracking now large amounts of electricity to be pumped underground too!
Gotta get that 5g out
