Astrum in 2014: Mercury is so interesting!
Astrum in 2024: Mercury is not necessary đ

We just gonna ignore that nuclear can power earth for thousands of years?

The solution is not solar, wind, nor tidal... Its nuclear

What's interesting about Mercury, is that it rotates around it's axis so slowly that you can "outrun" the sunrise, as long as you move faster than ~11 km/h. So it might be possible to create a moving base that always stays in it's twilight, where the surface temperature is somewhat pleasant. (It goes from -173ÂșC on the night side to 427ÂșC on the day side.)
Dutch author Tais Teng actually wrote an excellent sci-fi novel about this idea (_400 Graden in de Schaduw_, or "400 Degrees in the Shadow"). I don't think it ever has been translated, but it's a big recommend if you ever are in the situation to read it.

It has to be a swarm in order to reorganize for optimization over the variable solar output over time AND in order to dodge solar outbursts and magnetic storms

Interesting that nuclear isnât mentioned. This would solve a lot of our energy problems.

I wonder if dismantling a planet within a solar system, part of an orchestral orbiting situation of several planets together, might become problematic, or result in strange changes in the solar system.

One issue I never see addressed in these types of videos ... increasing the amount of energy arriving at earth should upset the energy balance considerably. Directing near 100% of the sun's energy to earth, even if transformed into something other than sunlight, is still going have to go somewhere. We would have to be able to dramatically increase the amount of energy the earth sheds as well.

you made a mistake at 6:35. 1kmÂČ is 1million mÂČ. so 35000 people per 1kmÂČ would mean that each person would have 28 square meters, not 3 square centimeters
67 |
My question: what happens to all of the planets beyond the sphere with less or no sunlight (or solar particles) reaching them?
56 |
6:38 How on earth did you get that 35k people per km2 means 1 person per 3 cm2? There are one MILLION square metres in a square kilometre. It's actually one person per 28.6 m2.

One idea that I've thought of (and actually employed in Kerbal Space Program a few times) is to make a giant solar farm on the surface of Mercury and have a massive beam that converts the solar energy into microwaves and beam them to the Moon, then to Earth. A side-effect I could see with that is creating massive invisible beams of death in space. A wandering spacecraft that stumbled into the beam wouldn't have a very good time.

6:36 thats quite the miscalculation manđ

One of my favourite episodes of Startrek tng is called "Relics" and has a Dyson Sphere in the story. It's such a great episode. It's the one with Scotty (James Doohan) making an appearance.
29 |
Astrum: âa dyson sphere could be completed as little as 31 yearsâ
Also my city builds a 12 story office building in 5 years

It's cool to see Alex covering more 'futurist' topics in his style. The optimist in space really suits him, and we need more of that.
42 |
One thing I rarely hear talked about is that in the case of a Dyson swarm, while having the panels be a thin as possible saves on weight, cost, etc it also decreases mass so much so that the orbit would be very energy intensive to maintain due to the pressure from the solar radiation.
14 |
I asked a super advanced alien about Dyson spheres. He laughed so hard. Eventually he told me, you are thinking in your frame of reference, we don't build giant balls around stars.
You are like a guy from 1850 imagining telegraphs and trains in space
14 |
But you forgot to consider the asteroids, comets, Coronal Mass Ejections, solar flares, solar storms, gravity of planets, the disruption of orbit by a nearby passing star, fluctuations in temperature, possible material and component failures and the maintenance. I would suggest considering the trojan locations in the Earth's orbit. They are gravitationally stable and would require little adjustments over the years. We know the science of trojan asteroids in the orbit of Jupiter and the Lucy spacecraft is going to dive deeper for that matter, so that might help as well.

The fact that the Dyson Sphere was actually inspired by a sci-fi novel goes to show that its not the knowledge that inspires ideas, its the imagination. To me that's absolutely beautiful.
