You make a valid point, but now the construction question's even harder!

You can certainly build something house-like out of gold, but not with the wall thickness conventional houses have. It would be more like a massive block of gold with some interior volume taken out.

So yeah, I know repraising the question: How would you build a structure made entirely out of gold? (It must be livable, mind you, though the plumbing and electrical wiring don't need to be gold)

It's like the old elephant thing.

"I wish I had enough money to buy an elephant"
- "Why do you want an elephant?"1
"I don't. I just want the money."

Thusly, a house made of gold may or may not be useful, but it is at least going to be mostly convertable from its basic building materials into either a house or (perhaps even via the built form, if contractually required in order to gain absolute position) any other given currency or good as one might subsequently desire.

Yes, probably including a large number of elephants. (Any estimates of how many? And how many elephants would one get for an elephant house made of gold, assuming you reserved enough value (possibly gold weighing as much as one elephant, for poetic symmetry?) towards the building of a standard elephant house? Useful links?)

And how many giraffes-high are any of these proposed houses, anyway? That's the most important metric, obviously.



1 NB. In another variation of the conversation, this would be considered a silly question. Please refer to Mr B Simpson of Springfield.

I prefer my houses measured in blue whales.

I'm not sure either of those would be an issue. Insulating your gold wiring from your gold walls, on the other hand...

That's why I said the above. You can't install gold lightbulb with gold wiring encasing in gold tube without electrocuting the enitre house (and you in it)

Very pure gold is relatively weak, as most pure metals are. But typical jewelry gold of 22kt (90% pure) is easily as strong as standard construction steel, and steel is already overly strong for the construction of regular houses.

At first approximation, we can assume that all metal structures can be replicated in gold. Thermal isolation is tricky, though I have seen aluminium foams that are in the same conductivity range as brickwork. I assume that a golden plate-foam-plate sandwich will work well enough to cover a building, and will also act as fairly weight-efficient floors and roof.

I am sure you can make gold-oxide based glass, somewhat coloured perhaps. Though I am not sure how much gold you can push into the matrix. There exists glass with 80% lead by weight, perhaps that's doable for gold as well. Gold glass might be a useful electric isolator as well.

Add in gold wires, gold cloth, golden slide bearings. It would be harder to build a 99% pure golden house, but I'd say you can make a house where every part contains enough gold to be simply called "gold" by jeweler standards.

Yeah, but that's just trace amounts. The interesting stuff are radiation -shielding windows, those are mostly heavy metal by weight. Lead or barium, typically. I just don't know if that would work with gold.

Since he didn't set a standard than you can dream up practically anything you want. It would be interesting to see an electric motor made from pure gold or the thousand and one things that you don't see, like gaskets and lubricants. How do you do cathodic protection of your water heater?

It's just a name that I thought up. Perhap more appropriate would be the Douches of Richard.

Yes, and that's for ordinary silver-and-copper alloys. Apparently, there is even an alloy with 99% gold and 1% titanium that can be cold worked and annealed to reach 660MPa yield strength and 800 MPa ultimate strength. That's beyond ordinary construction steel.

@morris, you can build iron-free motors. For some specialized applications, they are even the optimal solution. You could presumably make an iron-free motor even without permanent magnets, though efficiency might be low.

Okay.

I guess what I'm poking at is the silliness. The space station is proof that if you throw enough money at something you can make anything work. my friend Catherine chewed on lamp cords, and never got shocked. In this house that cat would have been toasty.

Inspired by soupspoon, I'd build a stock exchange with it. So if the stock market crashes, the stock market crashes.

Pray tell, in what manner is this still on a discussion level worthy of the Science board? If you want random natterings, ask it in fleeting thoughts thoughts for ships.
