How to Build a Dyson Sphere - The Ultimate Megastructure

I'm in love with space stuff :)

yeet

Why is there only so little likes

Are you a scientist.also why arent we creating the railgun thingy now?

i like the type of style you did with the video

Earth: Mercury may die, but it's a sacrifice... _I_ am willing to make.

WHAT DID YOU DO TO MERCURY

I come back to this video sometimes just for this comment

RIP mercury

Sometimes Kurzgesagt make the dumbest videos like this one . No civilization would go to the trouble of making a dyson sphere when you can just make a computer to simulate the universe and the simulated occupants of said universe would never grow old , be sick or die ...that is why we don't detect Aliens because they shed biology long ago .

lol good comment

psychological torture

Lol

Reduced to Dyson sphere

what if... we just use the actual element Mercury as mirrors?

Lol

lmfao

That's why the power bill dropped okay thanks bro

When I was building one at home, I had an issue with transporting the energy produced over long distances. No need to worry, this video was a great tutorial explaining how mirrors could be used to reflect the sun light to the collectors. It is a great school project. I fully recommend it. lol

Wow I just suck at building one than. Got a D for the project. I was able to explain the process but I was not being 247% efficient with my power.

hi hope my descendant see my comment here

Agree!

there is supposed to be only 1 reply here

It's all in the name of progress...

What about all of the atomic bombs going of in ever other video?

But the whole video focused on a Dyson Swarm, not a Dyson Sphere. If its a swarm, then it doesnt need to spin, it would simply need to orbit which we know how to do. So you couldn't "nudge" a Dyson Swarm because its not a single object.

it's main focus was on dyson swarms not an entire structure. he already explained what would happen if it was a dyson sphere stucture.

Kevin Godec honestly would be amazing and he would be the man to want to get something like this started lul. Love ya Elon

Why we don’t put solar panels on mercury instead of destroying mercury to build dyson sphere

@@secretunknown2782 Because solar panels are very short-lived compared to the timespan it will take us to harnes all the energy needed for interstellar space travel. Solar panels are not as efficient as we think :) They're still heaps better than fossil fuels at not destroying our planet, but it's still not good enough for very, very big energy generation. I've got my sights set on nuclear fusion, but that needs to be properly funded and isn't really at the moment.

Or a whole bunch of asteroids.

We just want earth, and probably mars

@@ExEBoss Nope. Mercury is many orders of magnitude more massive than all the astroids in the solar system. There isn't enough astroids to make a full Dyson swarm, and they're too far away regardless. Mercury really is the best solution.

I legit saw a comment complaining that removing Mercury would "fuck up astrology and mess up our star signs and zodiac readings"

Too late to explore the earth; too early to explore space; just in time to fix all of the problems

What technological limitations can you think of that prevents us from creating some type of partial Dyson swarm from mining with robots mercury and launching satellites/collectors to beam down energy and accelerate the process?

@@sw1tch327 The abysmal efficiency, recyclability, and maintenance of solar panels and the difficulties we would also have with capacity when it comes to storing that power.
On the one side. We might not need huge capacity if we can solve the problems with Solar energy. Solar Panels lose efficiency as they heat up and their efficiency is rather shit to begin with. But if we could develop solar technology that would allow us to control how much energy we take-in, whenever we need it. Then we wouldn't need to have an incredibly advanced energy infrastructure.
That said. Without that advancement. We need a good way to direct as much solar energy into the energy grid for storage for when it's needed. Batteries are essentially already at their best efficiency that we can actually get them. There's pretty much a chemical limit. So we can't just make a super-grid of batteries. They're expensive, volatile, inefficient for our purpose etc.
Super capacitors have the problem of having even less efficiency than batteries but they can output charge much faster. Not really fit for purpose.
Perhaps we'd find ways to use any excess energy that we harvest when it's not needed and pump it into a mechanical system that would allow us to convert later on.
I'm spitballing here but yeah. There's a boatload of issues with just receiving the energy. Let alone setting up the infrastructure that builds the thing.

​@@Unethical.Dodgson Well if you watched the video it covered that when it said to use mirrors. With that much power we can use kugleblitz batteries (maybe). And we can just not store whatever energy we don't need and use what we can and then we have a very high demand for energy storage

Honestly, most people would rather focus on space travel than current problems because it's easier and more interesting. There's a reason there are hundreds of sci-fi shows but none about feeding the homeless.

@@sw1tch327 sorry to necro here, but my concert is he said mirrors to direct to a place. If that place is on earth then we are going to fry the earth before the end. Even if we dont, if the mirrors have a glitch that much energy focused in one place could demolish any city (magnifying glass and ant). So we focus on an object in orbit, how do we get that energy here? We don't have a way to efficiently transmit energy across space. Right now the only way they can think of is lasers, and again with that much energy a bad actor could demolish a city. There is also a massive amount of energy lost to the atmosphere and then again with solar. The mirrors have to be able to direct in unison to a point. How are we going to do that? Not to mention it has to get into orbit, but the mirrors will act as solar sails. If we use the force of those to keep it in orbit then we run into the issue of sun spots. Then how do we rotate the mirrors to remain focused on earth? Can't be gas we would run out on the mirrors before long. Maybe some gyroscope, but we would have to have billions of satellites working in unison

You've lost the oportunity to say "UnLiMiTeD pOwEr!!!!!!!!!!"

the concept starts very simply first have the resorces of billians of earths negating the point of building this joke of an idea in the first place

@@shardinhand1243 You don't need "billions of earths" worth of resources, it i stated as much. And why would such a project be a joke? It is more grounded in our understanding of physics and thecnology than things like Alcubierre warp and wormholes.

@@paulohenriqueferreiradealm1893 also aside from needing more metal than we could get from every planet in the solar system, even if we made it, it would just be destroied by its own gravity, the suns gravity, and all the heat from it, but ignoring all that, the energy from it would only be practical to use for our solar system... which we would have already left for behind just to get the resorces to build this silly thing.

@@shardinhand1243 Well both the video and every other article that talks about a Dyson Sphere says that, at most, you would need just Mercury do do it, and not even all of it. After all, the idea is that the parts composing the sphere are as thin as you can get away with it, despite how wide than can get. We are not even talking about centimiter here, but rather millimiters, or thiner if possible. Such structure is not achivable as of now, but nothing on engeneering or physics prohibits it to be, given enough fine tunnig of the construction tecniches already available. It is still worth mentioning that this fine tuning, as well, is grounded on the realms of possibility.
Aside from that, the most known name is "Dyson Sphere" but, as the video points out, it would be far more accurate to call it a Dyson Swarm: millions of small, relativly speaking, pannels that collect all the energy of the sun and redirect it for use by the civilization, like a really dense fog covering the sun itself.
On the point of going to other star systems, there are almost no reliable way of making it there and back in reasonable times (reasonable in a intersstellar scale, which would still be around three to four centuries, go and come back) without the usage of solar energy. As far as we can tell, accelerating to relativistic speeds without the energy output of a star backing you, is simply too energy costly to be tried.
That is, unless we figure some new physics which allow us FTL travel, which we are not even close to.

@黃詩峰expensive and takes too long

@黃詩峰 Its more efficient to EAT Mercury so we can make the swarm

Yeah but if we had infinite power it’s pretty reasonable we could just boom snap and Mercury would back in orbit
