Previous Episode:
The Black Hole Information Paradox
• The Black Hole Informa...
The richest person in modern history, was John Davison Rockefeller, His net worth was three times greater than that of our richest tech billionaires, inflation adjusted. And the source of that fortune? Timely exploitation of a vast, then-untapped natural resource: oil. Well, the days of oil may be numbered, but there’s another natural resource that’s never been touched, is effectively inexhaustible, and has a dollar value large enough to disrupt entire economies. That resource? Asteroids, and the precious materials they contain. Astrophysicist Neil deGrasse Tyson predicts that the world’s first trillionaire will be an asteroid miner. The Rockefellers of the 21st century may be less like the internet and tech moguls of the 20th century and more like the old-school oil barons of the 19th century.

In the early 1990’s I was working on a Ph.D. at LSU and as all grad students I was required to present a “mini-seminar” for lack of a better term. My seminar was on the future tasks of scientists and the example I used was mining asteroids. I would pay a large sum of money for a photograph that captured the looks on everyone’s’ faces. The attendees were civil and suppressed their chuckles, but it was clear they all thought I belonged in a straitjacket with a residence in a nice quiet rubber room. Looks like I may have the last laugh after all.

*+Bret Territo* What the hell? The crew of the _Nostromo_ were asteroid workers in _Alien_ weren't they? And okay, that was a movie but surely it made it pretty obvious to even the most moronic dolt, that asteroid mining was a future potentiality. I don't know what LSU stands for but I'm wondering if it's some creationist university in some weirdo xtian country, or something.

Sue Mead think about the year 1990. Professors usually range from 40s-50s especially back then. These people were most likely born decades before the Apollo missions. I understand their skepticism, but their short sightedness is alarming, imagine if someone had proposed we'd have smartphones in 20 years time, they'd have been laughed off stage

I did a presentation in the late 90's on possible designs and advantages of biological spacecraft based on oversized terrestrial plants, in a Futuristics class. Everyone balked at it and the teacher even did the stereotyped hand wave to end my presentation without wasting another moment of their time. Futurists.

@kylegesin7178 4 года назад

Before anyone does any mining at all, we need to make sure we have strong tax laws with no loopholes for these companies to exploit. Can't let these already super rich people bring in this kind of extra weath, and allow them to a kid paying any taxes on it the way they avoid paying any on what they make on Earth already. We could fix the national debt, provide free health care for all, and free higher education for everyone if we just made the rich actually pay their proper fair amount of taxes. And before any idiotic right winger comes in trying to say I am calling for socialism, that is not at all what I am saying. I am just saying make them pay the proper amount of tax everyone else does, the same percentage of their income the rest of us pay, nothing more. Don't let them exploit any loop holes, and end up paying not a single dime of taxes of 11 billion dollar of profit like Amazon did last year. Just that, make them pay their fair share. That alone would solve all the money problems of the country, while having enough left over to increase NASA's budget by 10 or 20 times.

"Asteroid miners are gonna have to be careful not to crash the value of those materials with oversupply." Their very goal should be to greatly decrease the value of those materials, especially since they'll have a vast supply available. This way they're gonna sky-rocket progress on all the technological and engineering fields that those materials are needed, resulting to more profit for them and more efficiency for their extraction means. Also, this can lead to outlawing such mines on Earth, which could lead to great environmental and social (eg. decreasing child labor) benefits.

@ne9958 4 года назад

Vast changes in global supply can be detrimental to entire economies. Inflation is the usual result of flooding the market with valuable material. This is sufficiently different from cost reductions of technology due to maturity, commodity markets are less isolated to particular niches, so tend to affect the costs of more items meaning that inflation is widespread and affects the whole world economy. Hyperinflation is a devastating effect and can make the standard of living decrease. Also platinum prices may plunge close to aluminum, causing space mining to suddenly become unprofitable, etc. Managing the supply is much more preferable, profitable, and intelligent for investors in this type of venture. I'm not sure about the issue of child labor in platinum, gold, and rare earth metal mines. I would have to research further to develop an opinion on this subject... child labor is wrong, but platinum mines are in Russia primarily and I think this practice is not prevalent there any longer... again, I would have to research this to be fully satisfied in this. Mining can be dangerous work, and space mining will also be dangerous. Robotics will be the only way to make any mining safe regardless of where it takes place, and will be the signature of well managed mines in the future, on Earth or in space.

"oil, gold, diamonds, and other resources stole from places like Africa around the world," Are you aware that diamonds are so common as to be worthless? Also funny that you conflate purchasing with theft. As if those countries didn't get anything out of the deal. As for your last point, that's an assertion. We know nothing about alien life, let alone what political system they would use. And in _The Day The Earth Stood Still,_ an alien threatens to kill us all because we might kill us all.

Economic theories might be forced to change, since in a couple of decades the principle of scarcity could no longer apply to anything material. I guess we're way more prepared on the engineering aspect than in all the others combined. Lots of food for thought, and daydream :)

Keep in mind that during atmospheric re-entry, the atmosphere slows the objects down by turning the excess kinetic energy into heat. If importation of materials from asteroids to Earth increases as is often forecasted, we may be turning the sky into a giant broiler. Mining in space will need a market in space where the products would have a pricing advantage over material launched from Earth. Mining asteroids for a market on Earth would ultimately be self defeating.

Although the rare earth elements and precious metals would be the main prize from mining asteroids, simple silicates in the regolith could be turned into something similar to glass-crystal-quartz that would be capable of holding atmosphere, with light passing through. We could be farming in space, and generating oxygen.

Earth loses millions of tons of mass to space every year. Bringing a few hundred or thousand tons back doesn't make a dent.

Upcycle Electronics No, bombing is to pick up weird rocks, make them in to weirder rocks and then drop them.

In fact, to make it profitable it won't even be necessary to bring all the resources back to Earth. Eventually a good part of civilization and the economy itself will be moved to space.

@CloudsGirl7 6 лет назад

But getting to a more serious comment... I imagine that getting this level of interest in asteroids would also help raise our awareness of those space rocks we have yet to find that could harm us on Earth. ...on the other hand, careless miners could also inadvertently send some dangerous rocks in once-harmless orbits to a collision course with Earth...

@CloudsGirl7 6 лет назад

Warzed Arcanist Well, of course it'd have to be big - I'm not saying a softball-sized rock would reach the surface, not even car-sized. But one small nudge on a dangerous asteroid could be enough to give us a big problem. This could be caused by altering its mass (which would happen with mining). And oh boy, if those miners get bored and just start chucking rocks off from the surface of the asteroid... (Not against asteroid mining, though - I'd just hope for some caution with it... Even if Earth is a small target.)

@jonnnnniej 2 года назад

@@CloudsGirl7 that would be like saying ship captains would intentionally drive their ships into a harbor. It just doesn't make sense. And the repercussions alone would be reason enough for no one to ever do it. It would land them in jail forever and bankrupt them because of the useful material burning up in orbit. And if someone intentionally wants to destroy the earth I would say getting your hands on some nukes would be much easier and cheaper

@tsc9191 6 лет назад

"The Expanse" is an intriguing science fiction series which illustrates a possible future which includes colonization of Mars and the Asteroid Belt. The settlers of the Asteroid Belt perform mining operations. It originally aired on the Syfy channel which cancelled the show (not sure why). It was saved by Amazon.com after Jeff Bezos took an interest in it. It's a great show. It's both entertaining and thought provoking. There are many logistical problems which would have to be overcome. Consider the effects of massive over mining after an extended time period. Moving large amounts of mass from the belt's orbit to Earth or Mars would result in a disturbance of the orbits of the two aforementioned planets along with other planetary bodies. Redistributing the mass' location in the orbital plane would alter orbits of everything else in our star system. The resulting changes in the angular momentums of asteroids, planets and their satellites could result in catastrophic collisions. Check out the original 2 dimensional game called Asteroids that was distributed by Atari. It has nothing to do with mining Asteroids however it does illustrate the effects of altering asteroid trajectories and it's fun to play. Excellent video BTW. Enjoyed it very much.

Wouldn't it be easier to mine the Earth first .. then the Moon second??!! Considering it costs your weight in gold just to get in space nevermind to some object flying through space at 40K MPH.

@LuisAldamiz 6 лет назад

Some pragmatism finally! But the moon is as international as Antarctica and so is in principle everything in outer space. Have you ever heard of any mining project in Antarctica? There's a reason for that, I'm sure, and lack of minerals is not it.

@dontremb 6 лет назад

He mention why not in the video, but basically, the earth and moon are huge, so the majority of heavy elements are concentrated in the middle. We have no technology right now that would allow us to mine materials from planets or moons. Asteroids have the majority of their heavy materials in their core as well, but because they’re much, much smaller, it’s easier/cheaper to get to them.

@DJaquithFL 6 лет назад

Luis Aldamiz The Moon Treaty doesn't mention anything about mining being prohibited. Logistically it makes a lot more sense to mine from the moon in addition if it's Humans doing the mining gravity is a plus. Not to mention the water resources available. While I heard mention of robotics, I also know the failure rate in these harsh conditions. Also there have been a ton of asteroids that collided on the surface of the Moon. As soon as someone brings back 50 tons of gold I easily suspect it won't be worth a fraction.

@DJaquithFL 6 лет назад

Don Trembly As I mentioned .. the moon is literally covered with asteroid impacts .. hence the materials are on or near the surface.

@LuisAldamiz 6 лет назад

But the moon is much lighter than Earth, so a lot of those materials should be relatively close to the surface. The Moon is also very close to Earth compared to asteroids, with predictable cycles and a reasonable amount of gravity so stuff does not go around and gets lost in the cold vastness of empty space easily. Just like there are mineral deposits in Earth's crust, they should also be in the Moon, which is basically a mini-Earth, geologically speaking, a chunk of Earth floating out there with pleasant predictability. IMO the Moon would be much more feasible and operations there could also multitask for other purposes: intermediate port for other space exploration (asteroid mining included), tourist destination, etc. It's rumored that China already has a base there or is planning one for the near future, not surprising because it makes all sense and Chinese tend to be very pragmatic people (Westerners tend to drama instead, epic included, but also tragedy and sometimes unwilling comedy).

@shkotariq6138 6 лет назад

mining to much of rare elements won't make them rare anymore to earth standards but perhaps it will make some people more rich

@AsecasJavi 6 лет назад

That's a good thing. Rare materials will be cheap and constructions, mobile phones, and other stuff will be cheaper

@ridealone7933 6 лет назад

Shko Tariq, most of the rare earth metals are used for many applications like tech, not just for adornment. The issue of scarcity for these elements will probably be resolved, and that is a good thing overall. Oil’s prices significantly dipped in the late 19th century due to the abundance but it created so many applications for it, the price drop did not hurt.

@abz998 6 лет назад

Cheaper green energy and a lot of technologies would become feasible with abundant rare materials. Hydrogen fuel cells for example.

@FourthRoot 6 лет назад

Using water as rocket fuel in space is a poor choice. Oxyhydrogen rockets are useful right now because of their high specific impulse for chemical rockets and high TTW. However, above LEO, specific impulse becomes much more important and solar powered propulsion becomes king. Electric arcjet thrusters using the most abundant and least valuable elements as reaction mass becomes much more practical. And in situations that require high TTW ratios such as capture burns, thermite SRBs or oxygen-metal hybrid rockets could do the job. The hydrogen may be too useful to burn as fuel.

@brainmind4070 5 лет назад

Fourth Root Eh, acceleration from electric thrusters is so low, it may not be viable from an ROI perspective. Also, you need Xenon, a comparatively rarer material.
