- Asteroid mining might sound crazy, but it could actually become a more sustainable alternative to mining on earth. Precious metals like gold and platinum are crucial for green technologies, yet extracting them destroys the environment. But what if we could prevent that by mining in space?

We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world - and challenges our ideas about what dealing with climate change means. We look at the big and the small: What can we do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess.

Never thought i'd stayed to watch an ad about space
I guess this is one of those ideas which can pose a great threat to the pockets of the big guns.
Brilliant video ! Thank you for the interesting content ❤️
Best ad on CZcams I’ve stayed to watch
An ad?
I just got this as an ad and I stayed for the scientific content~
Interesting video - space mining certainly raises many questions and have had recent discussions on this topic!
Absolutely love this video, very easy to understand yet informative! Great work!
If one brings enough metal to make prices drop, it will kill competition. Then just set price low enough to prevent anyone to start and enjoy your monopoly until next asteroid miner drops a cargo.
Molto interessante!
Legend - keep the videos up
Yeah soon you'll be as famous as great big story
Nice
Im probably the only kid sitting on my couch drawing an asteroid mining machine blueprint.
Video molto interessante e anche molto simpatico!
This is a really great video, very well made
im excited!
Why do people keep using the same old argument about price scarcity? The mining operation doesn’t become unprofitable because you magically pop out 5 trillion tons of platinum. You still have cost attached to acquiring said asteroid and the mining operation itself. The price won’t be set by earth mined mineral anymore, and that’s the goal. Whatever the cost to mine the asteroid and bring it back has to be competitive with earth mined mineral; that part doesn’t change whether you’re getting it from space or opening up a new mine. Once you’ve have a mining operation up and running, the profit comes from the difference between operating cost and the price people are willing to pay for said mineral. The reason is why it’s not economically viable is because the cost and technology requirement is too high. Not because scarcity induced price drop. Aluminum used to be the most expensive metal on earth until people found mines and processes to make it economically affordable. No one betted against acquiring aluminum because it would cause a price drop. The only industry that would affect because of the drop in scarcity is jewelry since people desire scarcity. I’m sure they’ll move on to other exotic material/processes, and obviously I’m less inclined to care about what makes them money.
Where do I apply for asteroid mining employment? I want my assignment to be in outer space please.
i love this channel lot❤❤❤❤❤❤❤❤❤❤❤❤
At least that way a big part of the mining on Earth will become obsolete,that'll be great for nature
So once the metals are melted by the mirror array, where does the liquid metal flow to? Up? Down? How is it captured? Purified? Returned?
The value of a rock is nonsense when you do not consider the cost to work with it. What is the net profit?
i think the point is that mining asteroid is profitable because of the resource price, but mining asteroids would flood the market trasforming a super rare resource into a common one, making it worth noting, that would make the asteroid mining unprofitable.
The demand for these metals will keep the price high. Look at gold mining, currently.
More gold is mined, more than ever in our existence. Better equipment produces big yields. Price of gold is pretty high, and even if we started adding metric tons to this, the price will never go back to $350 a troy ounce like it was just 16 years ago.
+ u can pump all the excessive co2 u want out there cuz its outerspace anyway
I just remember when Seeley brought it up on Bones
But what happens to the pebbles ? Pebbles would be everywhere.. causing more space junk. Wouldn't that be dangerous for space station, It be like a bullet in space.
I guess they never thought of that( even I didn't think of it) but it can be dumped on the moon
👏🏼👏🏼👏🏼 amazing , hope billioners should take that chance to finally leave earth in peace
What piano song is that?
9:27 including farming
I think the solution with mining is to have the asteroid of our choice orbit around the sun, close enough to melt. Maybe a series of close detonation can help the asteroid make its way toward the sun, hopefully we can measure what speed and what angle it should approach the sun, in order to get it close enough to melt it thoroughly, if timed right we can have it get close enough to earth to orbit earth.

I'm actually Italian :) But thanks!
I watched this in an ad
I think Elon musk will still pursue it. Yes prices would crash but having that many times more the amount on earth pretty much gives that company control over that material , until of course more companies start mining. I think backwards inflation might actually be a good thing and hopefully there is a good point where money value stays , instead of the crazy inflation were seeing today
It's all interlinked and a complex topic to unpack. The question still remains if mining can be done sustainably?
Imagine a distant future where space colonization is made illegal by the forces of Earth because all the mineral resources of the near earth asteroids have been depleted and the scarcity threatens earths infrastructure.
Just short the stocks of current mining companies and start mining asteroids. You wont get direct profit from asteroids, but will gain from the short sells.
You could even mine water.
Can't believe you can get a degree in space mining. Seriously don't want to pay down those student loans on a degree that will yield employment 40 years from now. Maybe.
I like a waterplasmagun medium size with a airballoon
Human greed knows no boundaries 😭😭
And so we come to the failure of modern economics it would be best for the world it could take 10 years (time it now takes to setup new mines already) BUT we won’t do it coz there’s no killer profit for “the investors” who now don’t pay for the”externalities” of current production methodologies. Ergo if you properly “Price” the true cost of climate change and environmental degradation thereby you change the decision equation. So the industrial revolution made everything cheaper BUT if we make expensive minerals cheaper traditional investors who profit now from scarcity somebody loose their shirt BUT the rest of us and whole economies and industries rise due to cheaper availability - Economy of Scales
kick in changing the production equation sense the private marketplace doesn’t. What were the cloth and spice traders of Spain Portugal Venice and Genoa gone for years reckless dangerous unknown but coming back revolutionising their economies
Asteroid mining can be easily sought after and is achievable within less than a decade or just a few years. How do we do so? By building a space elevator:
The key idea is the Orbital Ring version of the space elevator, not the geosynchronous tether concept you are familiar with. See, for example, Paul Birch's writings: www.orionsarm.com/fm_store/OrbitalRings-I.pdf
The orbital ring only requires tethers about 300 kilometers long which is technically feasible with common material like steel, but ridiculously straightforward with better and already available material like kevlar.
There are some important questions. First, how much would it cost to do something like this?
We need to send about 160 million kilograms of material into space (See Birch's boot strap estimates in part 2: www.orionsarm.com/fm_store/OrbitalRings-II.pdf) We have rockets available at $2000/kg costs to LEO today in "mass production" mode, which is only about 10-20 launches per year. Compared with the couple thousand launches necessary for a space elevator, $2000 is an unreasonably high upper bound for launch costs.
We also need to include the cost of materials. A space elevator is about 98% steel (though you can use kevlar for the steel) and aluminum, 1% kevlar, and 1% other such as superconducting magnets. Most of the mass (98%) cost around $1/kg, with an average cost per kilogram of no more than about $10 per kilogram.
Summing the above up, we get about $430 billion in launch costs plus another $1-2 billion in material costs.
In other words, we can have a space elevator for less than $450 billion - significantly less than one year worth of DoD spending, one bank bailout, many times less than a variety of pointless wars, etc. This is well within our reach financially in other words. We'd have immediate access to viable asteroid mining industry. Because the cost of delivering payloads to LEO drops to about $1/kilogram, we can now retrieve asteroids with trillions of dollars worth of minerals for mere tens millions of dollars in addition to having an easy viable way of returning those resources back to the surface.
While I find it fascinating how much thought and research you put into this I believe the you forgot about the obstruction of NEO, for example satellites views and signals may be cut off, and any debris in the nearby area would surely damage this elevator and fixing it would not be an easy task nor a safe one.
That bit at the end is what I cannot stand -People obsessed with utopia/
Why can't we bring small asteroids down to earth??
We need to realize that any mass ejected from earth lightens earth's mass, and vice versa. We need to THINK. At 1:25 he admits the more "green" we get, the more we destroy earth.
Khajit want space coltan yeeees?
Lucy sky diamonds nothing to with lsd at all 😂
It's too bad there was no information about how the mined materials are to re-enter the atmosphere.
