Dyson Sphere by capnhack Dyson Sphere by capnhack
Heres a different take on the concept of a dyson sphere. For those who dont know, a dyson sphere is an enormous man made environment made of either ring(s) or a sphere with the radius of a planetary orbit. On the inside of this giant structure is a star which gives the environment its energy and warmth and light. See here for more info: [link]

Instead of having one ring, as in ringworld or halo, this sphere has several all locked together at two poles. Night and day are created by the inner rings which are static, with the outer rings rotating around them. Rather than having day and night the same length as in ringworld, a person can choose whether they want longer nights (by living closer to the poles) or longer days (by living closer to the equator). This would allow for massive expanses of ground that is perfect for agriculture where the days are longer, as well as enabling the rings to have some kind of ice caps in order to create an earth like weather system.
Id be interested to know whether anyone has seen a dyson sphere of this design before, because i havent :)

Modelled and rendered in Cinema4D, tweaked in Photoshop.

I prefer my own version

I think i once saw something similar, without the inner rings and fewer base rings. I think it was from some halo fanart, im not sure. But this is pretty well thought and made!

Very imaginative!

To augment your explenation: A Dyson sphere can also be defined by a network of orbital satalites of sufficient quanity.
If you've ever seen the movie WAll-E, you might recall Earth was practically enclosed by artificial moons(Including Sputnik).... this in a way can also be considered a Dyson sphere....

Nice render though.

Nicely done. I remember that Larry Niven (the author who first conceived of a ringworld) suggested the idea of nesting ringworlds rather than building a full shell, but I have never heard of joined ringworlds. It seems like the building materials wouldn't be able to hold up to the immense forces involved, but it is still a neat idea and an awesome visual.

True. I was more worried about the structure breaking up at the poles because of the stresses involved in spinning up such huge structures; you'd get huge torsion stress if you didn't spin each ring up at exactly the same rate. But then, if you could create a material strong enough for the ring to hold together in the first place, this probably wouldn't be an issue. I guess it's kind of moot anyway, since your drawing is still awesome, but I'm a physics student, so I think way too much about these things.

thanks :)
my thinking is that joined rings would be more stable than a single one. with a single ring if it slips to one side slightly (which could happen considering its only stable along one axis) then youd be pretty much screwed, but with a solid shell or joined rings youd get the same gravity being applied equally over all three axes. in reality the rings should get wider the further from the joint they are to make up for the extra mass at each ';pole' tho.

That's actually one of the slicker designs I've seen. Most of the searches I make come up with either Dyson Swarms or Dyson Shells, and the song I'm aiming to make really doesn't have that kind of image in mind.

The other design I rather liked wasn't a far cry from that transit system in the movie Contact (or this design either). One where there would be two stationary rings, one vertical and the other horizontal - Lattitude and Longitude rings. Within them would be two rings connected at the poles and rotating in opposite directions. Outside the Lat/Long rings would be two more that also spin in opposite directions. On the inside of each ring would be a belt of energy collectors (solar arrays or the like). Of course, this idea doesn't function as a habitat, but rather a single-purpose generator that would relay its collected energy to series of sattelites aligned with both poles, the center sattelite taking the bulk of the relay and dividing it amongst the surrounding sattelites which will then relay it to the habitat in need of power (large ship, station, planet).

And the technologies are already available, or not far down the road. It's just a matter of having enough resources and large/precise enough ships (or controlled ring boosters) that could safely align the rings around the star.

thanks for your comment and the watch :)

ive never thought of using a dyson sphere purely for energy generation, thats a pretty nice idea. i might have to nab it for a future pic hehe.
