What many people forget is that the precious metals on asteroids aren't just the coinage metals. Tantalum is used in all electronic devices and we only have less than 50 years worth left. Tantalum is a heavy metal which means it should be plentiful and asteroids even if it's rare down here. The incentive to start asteroid mining isn't just about profit it's about the continuation of our civilization as we know it. There is no other alternative but to get metals like tantalum rhodium rhenium and other rare elements from extraterrestrial sources if we want to keep making electronics and manufacture chemicals ( many of these metals are used to make catalysts for industrial chemical production).

Same goes for all metals, only 1,000 years left at max, even with recycling. Source- www.roperld.com/science/minerals/minerals.htm .The huge time delays of travelling the vast distances of space, and the massive amounts of materials required for building and maintaining ships, industries, and civilizations, along with the enormous levels of energy required to propel and power them all means; the logistics involved in space travel, trade, and colonization break down into a series of never-ending diminishing return feedback loops. Even without economic limitations, it seems too impractical to import materials even to other zero gravity stations, let alone a planet's surface. Civilization appears to be impossible to support for more than a few centuries at current technological levels. Every other intelligent species in the Universe probably encountered the same insurmountable problems, and then fell back into the stone age on their home world, which is why we never hear anything from anyone out there.

Author's Note: Ironically this video was scheduled to come out late afternoon on Thursday but got hung up in processing, which happens sometime with youtube, and just popped off on its own at 3AM my time, so no I've not decided to put them out at the one time of day that ensures only the night owls on the west coast or my east-asian audience will be around when they come out. It's been suggested that statistically the best time to release is mid afternoon eastern time Fridays so that might be when the next one comes out. Anyone's thoughts on the matter are appreciated.

Not quite sure what you mean by "...statistically the best time to release is..." are you being ranked somewhere by a stat like # views in 24 hours since release? Ignoring that for a moment, the way I use youTube is, from time to time I check my subs and watch new things when I have time after I become aware of them, so I don't see a "best time to release". Now returning to the idea that someone or something is scoring you (which could be defeated with bots by the way) I think the day of the week would be more important than the time of day (I assume you would want a weekday?) so Monday and Friday are out because some people are ahead and some people are behind. Can you link to info on why late afternoon is good?

Oh they have some sort of suggested videos system that apparently runs heavily on how much folks watch when the video first comes out, down to the hour, so I guess it matters both hour and day. I don't really understand it though, its something enough folks have told me that I imagine its probably true, the channel tends to attract folks heavy on brains and knowledge.

I have submitted a set of French subtitles for this video. They have now become available (by selecting the Settings icon, then Subtitles, then French). Although I found the auto-translate feature useful as a basis, I had to edit practically all of the suggestions, and many of them did not make sense at all. Given the specialized vocabulary used here, If we are to get serious about closed captioning to other languages, we will have to have, for each language, a list of terms to use consistently across videos that will end up being translated by different people who, in general, will not be professionals. How do you translate Post-Scarcity Civilisation in French? Post-Pénurie? Post-Rareté? Both sound odd to me, although I settled for Post-Pénurie here... Why not Ultra-Abondante then? Things like that will have to be agreed upon... Translating a thirty minute segment takes about two days of work, more if you are meticulous. So this is quite a commitment! But the job is captivating since it lets you ponder what is being said, which packs an usual amount of well researched material. I can only imagine the number of books that were read and the hours that were spent thinking about the topic to come up with the material! Great job Isaac! Let me know how you feel I can help.

Yeah I only speak a little German which gets rustier every year but even that was enough to show me not to trust the auto-translate, else I'd save everyone the time and do them all in every language. My advice to folks doing the translations, for which I'm very grateful, is to not worry too much about purity of translation in favor of saving time, and just leave technical terms in English if there's no obvious equivalent.

Isaac Arthur There's always the difficulty of cultural translation vs. transliteration, which I think Andre was trying to get at. But I reluctantly lean to the convention of leaving specialized jargon untranslated, because that seems to happen at large in the world of advertising and commerce - brand names get phonetically ported all the time (except where they come out sounding like vulgar or obscene terms). I still remember hearing one commercial in I think Korean or Chinese, and the word VISA pops out like a red dress on a sidewalk obscured by trenchcoats and hats.

I said more on this to another commenter; but Gold has physical and chemical properties almost as unique as Helium, and an increase in its supply would not necessarily drive its price down. Throughout continents and civilizations, Gold has been valued as a reliable, unforgeable currency medium, and currencies that do not derive their value from gold are prone to boom-bust cycles and political or financial manipulation.

@Phantom Ooze Hi, economics major here so I am not sure where to begin. Asteroids are not planets. Planets have orders of magnitude more mass and thus material if we were to guesstimate based on modern day prices would be far more prevelant. If it was just a matter of resource, then belt mining is among the most least efficient procedures of mineral mining in sci fi. And god forbid the price of silver dips sharply because some dick muffin named Dave found an asteroid practically made of it the size of Eros and now boom the economy spirals out of control. Supply follows demand and vice versa, asteroid mining makes the economy more unstable unless we talk about subsidization from a larger power or guilds of fleets working to basically 'disassemble' an entire asteroid with portions being dictated on market value at the current time. Overtime, valuable asteroids have been stripped away by either guilds or sold to larger companies that turn the raw ore into product. The Belt makes much more sense as a manufacturing and mineral reforger and builder which the expanse does have with companies like Tycho in the Expanse. I like Isaac but his economics knowledge here and said impacts are at best surface level. Saying they would be a millionaire only makes much sense when the belt is colonized (IE: Like a gold rush.). After, the economic opportunity basically shifts to mineral refinement rather then the actual asteroids themselves. I suppose larger asteroids like Ceres and Vesta in the expanse could form their own city-states with strong diversification from minerals to finished goods for space travel, definitely. So uhh no, I think it is Expanse: 1 SFIA: 0 i could be wrong, this is mostly just an argument with no sources so take it with a grain of salt, but the only real reason in a Type 1, maybe going to Type 2 society would use the Belt is essentially as the heart of where finished goods as made, before they are shipped to a new star system or to a local planet. I dont see habitats being spun except for major political centers or spatial manufacturing factories essentially. If you mining and not under a large sort of group, you are probably a poor belter trying to make a living on the ore or maybe even just blowing them up to make space for ship travel. Now if you were a part of a mining guild or were heavily subsidized by a state, uhh Ignore basically the above, lol. Yeah you will be a millionaire then.

As to imports... Maybe most important - no one on Earth will finance asteroid mining or any other industry in space that doesn't quickly return a profit on Earth. Yes, NASA or some similar agency might do some small scale stuff, but the funds (and materials) to develop real industrial infrastructure in space will have to come from space. We will build the first habitats to support those industries, not the other way around. After that there's a tipping point, when population and industry are large enough, and then most space resources will be utilized in space. (That's when we can start talking about orbital cities and megastructures.) Eventually the relatively small Earth population and economy will be an unimportant part of human civilization, but the seed money will have to come from Earth, and it will have to turn a steady profit for Earth investors.

Bo Zo and Isaac Arthur the first INDUSTRY in space may well be "filling stations" as proposed by Planetary Resources, Inc. - the harvesting of water from C-type asteroids and bringing that back to GEO and LEO; processing that into LOX and LH2 to be used for orbit maintenance. That will require the next generation of satellites be designed for resupply, of course. Note that with a huge amount of fuel and oxidizer available, a special spacecraft could go around collecting orbital debris, a worthwhile project.

Without running the numbers, I have to tentatively agree that getting ice- derived fuels and water from near-earth orbital objects would likely be cheaper than hefting it from earth in the long run - especially if we find out that some of those objects are dust-covered ice chunks that don't melt due to their thermomechanics. Imagine bringing into LaGrange or HEO a chunk of ice containing more water than all the Apollo and Orbiter program launch exhaust combined.

I am surprised that I can't find the suggestion of an isotope separator, based on the mass spectrograph principle. In space you have energy in abundance, and you need to produce structural components from what you find. Matter is few in space and you want to use all of it and separate elements or even their isotopes to obtain what you want. Also, the technique could be crucial to fully separate reactor waste from a molten-salt breeder reactor. This is the method to start using not just the fissible part of the heavy elements, but the fertile as well. So starting on earth in the energy development, the separator technique can be put into space to help building the first extraterrestial living space near earth, in the trojans or on the lunar surface. So one can experiment and build sustainability in space before further venturing into the solar system out of direct emergency help from earth.

It's not even necessary to separate raw mining ore at the isotope level; there's an alloy-building process called 'Electronic Beam Deposition', which involves taking measured quantities of raw elements in a vacuum chamber and vaporizing, then depositing them into a formed ingot of uniform composition. A similar process could be used to break down ores; it probably isn't because the abundance of things like oxygen, water, and acids on earth allows for faster, less energy-intensive mass processing. I fully agree, though, that the Moon and NEO should be a proving ground for engineering techniques and sustainable designs.

You want to separate your raw ore? Big mirrors heat up spinning crucible. Centripetal force pushes heavier elements to the outside. Shave off the outside few layers when cold and you have removed the vast majority of the good material (heavy metals). Reheat this material into another round slug and shoot that nice stratified material slug straight out of a coilgun towards LEO. This also leaves behind huge ingots of turned nickel/iron which you could probably sell to someone to I'm sure. Send them where they are needed with your coilgun too.

The things people do in pursuit of gold are often sordid and, to say the least, inhumane. In economic terms, gold is one of the few things that has sustained its value and viability over dozens of centuries of commerce and economic growth and collapse. In light of the increase of uses and demand for gold in industry and research, an increase in supply would hardly demolish its value. Two of the things that make gold so valuable to begin with are -= the ease of working it; it is almost as ideal a solid in some respects as Helium is nearly an 'ideal fluid', and -=it is a non-reactive metal, which puts it in a rare (sic) category; the other two metals most commonly used as currency are in the same chemical family; silver and platinum. So since it retains its physical properties over time in many different forms of use and storage, it is as unique as the H2X compounds in the chemical realm. Paper and digital currencies can always be forged (or 'cracked' in the case of cryptocurrencies); you can't forge elements without some serious investment in radiochemistry that would nearly predicate not needing to illicitly create currency in the first place.

How would we actually use asteroid material in space? we have to smelt it and purify it, and on earth that means melting it in a big pot, inject other elements like oxygen, molybdenum, carbon, and chromium, and drain it out of the bottom (to avoid slag). And then it is forged and machined it into parts. In space we could easily run out of alloying and doping elements. How would metalworking and machining in space work, especially given that it aims to produce spacecraft, mining, and smelting machines, and fusion reactors, which all require strong, temperature resistant, lightweight alloys? Merlin 1-D rocket nozzles are made of niobium. Fusion reactors require superconductors like yttrium-barium-copper-oxide, machining requires super-hard materials like diamond, aluminum production uses consumable carbon electrodes. Hall-effect thrusters require a boron-nitride anode. Are we expected to get all this stuff from transmutation if we can't get it directly from asteroids?, And even then transmuting elements produces a heterogeneous mix of isotopes that probably more difficult to separate than asteroid ore and would require other consumables like concentrated nitric acid.

Rare Earths and similar aren't particularly rare on Earth or similar, carbon certainly is not hard to find in asteroids. But keep in mind you can still melt stuff in space, you just need to dump the ore into a closed container and spin it like any centrifuge if you need gravity as part of that process.

actually is probably an advantage to process metals in space. Melted in a vacuum, it would conserve heat and thus use less energy. The purification steps could certainly be carried out in a vacuum, and there are a lot of advantages to having no atmosphere to contaminate the metal.

You can make alloys in 0g that you can't back on earth as well. You won't be using the same processes as on earth. Nickle is also very common in M-types so you would probably be using a nickle/iron alloy of some kind.
@adambecker9692
@adambecker9692 7 жыл бұрын
You can use the Mond process. The Mond process is easiest on nickle and iron which is the majority of the metal. The Mond process is like distilling metal atoms out by sending in carbon-monoxide at the right temperature/pressure combination to make a metal carbonyl such as Nickel tetracarbonyl or Iron pentacarbonyl. Ni + 4 CO → Ni(CO)4 (1 bar, 55 °C) Fe + 5 CO → Fe(CO)5 (100 bar, 175 °C) Of course the container holding your regolith has to be lined with some other material or it would also dissolve your container. You distill it with CO gas then use vapor depositing onto a heated surface to deposit the metal and regenerate the CO to reuse. Varying the temp and the pressure of the CO determines which metal carbonyl is likely to form. Then you drop heated balls of metal through the gas to deposit layers of pure metal. This is how nickle is refined on earth.

Thank you. Again, you push the envelope in fact and plain language. This video will be quoted A LOT to inform the pathologically clueless. As always, I reposted this on a few dozen spacebook pages. Also - Isaac how cold or hot will the relatively bigger asteroids be? I'd say very cold on the outside, and heating up that material to become processable (let alone creatring structures inside the asteroids) would be a hurdle. On the contrary end would be the cores of these structures might be natural radioactive decay reactors (oklo) and thus fairly hot.

I think it would depend a lot on composition and size. They should all be warmer than say a metal marble place at the same distance since they will have some fissionable materials but for things like the belt this should be minimal... it might be a good way to hunt for supplies of Uranium for something like Orion/Daedelus or local reactors where solar isn't optimal if fusion isn't around yet. Ceres is thought to have a core temp somewhere around 2000-2500K, but Vesta would be a lot lower and I suspect even from the big ones after the top 10 or 100 maybe you wouldn't get pressures and temperatures much beyond Earth surface normals. I'd imagine it would often be convenient to build your habs right at the center with that in mind.

+Isaac Arthur I've seen the 'hollow asteroid for habitat' a bunch of times. It strikes me as risky and inefficient. Potato shaped objects (everything except Ceres) are probably full of cracks and voids. A hollow space could be expected to shift. Deep rock miners on Earth have to account for this all the time. The odds would be better on Vesta but why take the chance? A constructed shell of rock and water jacket may take longer to build but provide a more sure structure. A shell of a few meters of rock and 2 to 3 meters thick water jacket aught to be enough of a radiation shield. It would probably would also put up with collisions with debris a few cm across moving 3km/s. The shell would be hosed if something a meter or more in size hit it at 3km/s. I picture a shell that is kept non-rotating attached internally to the axis of a rotating habitat. I'm not sure yet how to keep the habitat powered since the shell would cut off natural light... some kind of electric power transfer at the axis perhaps.

+Khannea Sun Tzu While I understand the hab-in-hollow-asteroid design I've tried to figure out the Mont Blanc tunnel reference. Perhaps you can help. According to Wikipedia the Mont Blanc Tunnel was built in the early 1950's. Explosives were the primary excavator tool. Excavating an asteroid with explosives would probably mess up whatever little consolidation it had and likely result in either one asteroid becoming many or a slow-motion cave-in. I was thinking that maybe a Chunnel or Gotthard Base Tunnel style excavation might be more suitable. Both used giant metal worm excavators reminicient of Dune worms. They make convenient round tunnels that are buttressed immediately. You'd probably want a tunneller an order or two bigger though, to accommodate cylinder or wheel habitats big enough to not make occupants sick.

The Earth itself will "survive" regardless. Since the Moon nor asteroids have life, I don't see the proble. Outside of some vague notion of what the "natural state" of the solar system should be (although its changed significantly over its lifetime), I don't see an argument for not doing it.

Large powerful relatively stationary reactors would be much better as 2F-MSBRs (2 fluid molten salt breeder reactors), to burn the much more plentiful fuel thorium. A mixture of MSRs and 2F-MSBRs is probably best.

Solar is cheaper and lighter. You can have all you want. You can make solar gear from materials on asteroids, no need for refining fissiles or importing expensive Earth-launched equipment. Even crude, inefficient solarthermal systems might be good because they're so simple - you can make almost the whole system out of low grade iron. You just need a mirror, a few miles of pipes, a steam turbine and some water. I'm a fan of nuclear power on Earth, but not so much for most space stations. Solar is just too easy.

Neat Gifts The condition is called Rhoticism because it deals with Rhotic sounds, which are usually denoted with an R in the Latin alphabet. The sound is hard to classify linguistically, and plays odd games with phonotactics (the way sounds interact) so it isn't surprising that some Rs can get through if the surrounding sounds help out. Perhaps a linguist could benefit from these videos by cataloging which words Issac is able to say. They'd have hours of material as a sample and could maybe get a better handle on what makes Rhotic sounds work.

Just found your channel with the last couple days and I'm very impressed with your content and am loving it. While I already knew most of the actual mechanics and actions discussed it's only been fairly recently that I've learned the mass within any of the asteroid belts is far less than weve always been lead to believe. I grew up during a time when the prospect of mind ng asteroids would solve the problem of earth's finite resouces and I never stopped to consider many of the issues you discussed here that would limit it's usefulness, well except the part about crashing markets, but I assumed that would be handled the same way is it currently done with diamonds, and how OPEC tries to with oil, by controlling the release of the resourses so as to maintain their high value. This could put whatever group of companies that were able to pull off the mining in a very unique and powerful position were they would have stockpiles to pull from for their own use, while still being able to sell to others at high prices and realistically I could see how this could lead to what I always thought was the unrealistic mega corps that often exist in sci fi. Since if you have stockpiling resources, to maintain market prices, why wouldn't you put those resources to work in other ways? For example, if you are buying your launch vehicles to move people to your transfer point, be it in orbit or on the moon, why not build them yourself with resources you have sitting around? So eventually you, as the company, could be conpletely self reliant yet still be bringing in $100's of billions of dollars in minerals and ores each year. Maybe the idea behind the political structure of Eve Online isn't as far fetched as it seemed, were instead of country or planetary governments you have corporations. I mean once your company dwarfs say the entire US government, economically, why would you allow yourself to be limited by that government? At that point they would need you, far more than you would need them.

In terms of bringing asteroids back to Earth; my view has always been that this would be used to form the basis of space elevator stations/"cheap" shielding for other space installations. Certainly in the early days before other launch systems have been created, even having a large warehousing/transfer/housing capacity in orbit which you didn't have to expend massive capital on to launch would be hugely advantageous. A crushed rock and epoxy or otherwise fused rock shell would be easy to shape and the majority of your raw material for this would come as a byproduct of mining the more interesting material. Anyway; really enjoying your videos - as you note there is not a lot of discussion on the wider impact a lot of these kinds of technologies would bring and I find you go into these enough to encourage serious thought without getting bogged down. Keep up the good work!
