I wonder if building an entire Dyson Sphere will decrease the heat output for everything around the sun. I'm sure theyll be spread out enough to avoid that and to avoid a collision chain reaction if something hit one.

I did an amateur calculation for fun once about a dyson swarm If we managed to catch 1% of the sunlight, we'd get enough energy to cover all the energy needs of all of earth projected of this century 1000 times over in ONE SECOND. Just imagine that. So much energy we could literally spend it on anything and we'd still have more than we could ever use in thousands of years!

9:34 Dyson swarms don't completely surround a star. The space between them would be enough that it would barely be noticeable on Earth.

I love that you bring up “Civilizations”! Loved those games growing up! They are the reason I became so curious about science, space, and human history.

I'm not sure how the orbits would work, but couldn't we just set up the solar panel orbits to be like a reverse torus, mostly taking up space at the 'top' and 'bottom' sides of the sun relative to the earth? The sunlight heading toward the planets would be left alone, and I'm pretty sure that kind of angle would allow for the collected sunlight to always be available, rather than the mirrors being stuck behind the sun at times.

This video makes it look like that a dyson sphere creation is a mix of a incremental and tycoon game

I think we'd have to not only put aside our differences (to redirect defense spending) but also create a better balance of short and long term thinking. With the way most people think today, even if there was no need for a military I don't think the money would go into generational projects. That's not to say there aren't some areas that help people in the short term that couldn't use vastly more funding but short term projects have just as endless a demand for money as a megastructure. Achieving such a balance would be even more impressive and difficult for the species IMO than world peace.

As the solar sails would not compare in size to the sun i think its very likely the earth would not be effected much by them. Like there are a ton of dust particals on a lamp but we only see it dim a little bit.

Most importantly, we could use the dyson sphere to create black holes made out of concentrated light, then we would be able to feed matter into the black holes and extract the energy that made that matter with 100% efficiency by a weird process involving reflecting photons.

The part at 5:21 where Kurzgesagt mention that “close to the Sun means less moving stuff around” is false, the way orbits work out is that it takes less energy to lower your perigee from your apogee, and it’s more efficient the higher your apogee is. For an orbit like Mercury’s, where you are already close to the Sun, your orbit is moving faster than planets which are further out, so it takes more energy to lower your perigee by the same distance, so it’s not that practical

6:27 Oh my god I didn't even notice before that they made a Star Fox to Slippy Toad here ahah

I have a tip- ur a great KZfaqr and i subscribe - but I’d get like a green screen so you don’t block to much of the screen.😊

oh yea, what would happen to people on earth when the sun is covered?

Dyson Sphere: Forget about global warming, this is the ultimate recipe for solar system warming.

So you harvest the energy from the sun. How do you convert it to useable electricity?

Yeah ❤

1:20 it`s a "dyson sphere project" reference

I am kinda surprised that Nasa has not tried fusion reactions in space. Also wouldn't we lose our heat and light source if we put a Dyson sphere around our sun?

yea, will be very cold

But what if we don’t get a any light building a Dyson sphere would be like blocking out light so it would get much colder over that would be good that could actually solve global warming

you are very good videos

What Irony (10:35) Considering current news i doubt they real but still

the move to "renewables" is actually an evolutionary step BACK, a big one! It massively DECREASES energy density, requiring a massive INCREASE in effort to produce the same amount of energy, while at the same time greatly reducing the reliability of energy availability. And the current trend is to go back farther and farther, faster and faster. I fear that if this trend continues for another 2-3 decades we'll be back striking rocks together trying to make stone tools.

That "please" at 0:24 sounds so genuine, sincere and sad, and hell, he at one point (if you go frame by frame) even looks like he is about to cry: i.imgur.com/XwyUUcP.png Don't be sad Tyler, we love your videos!
