7 comments on “Earth’s Dyson Ring?

  1. Im guessing it would depend on the total density of the debris/objects that are in orbit? The image says its exaggerated, i wonder what the density per cubic meter this stuff actually is and what the rate of increase is per year or maybe decade? I wonder also if the inner rings rate of density increase is the same as the outer ring? It looks denser in the artist rendering. Just wondering……..

  2. Yes, I was thinking about the density too… I would think that if it was a TRUE Dyson ring/sphere setup, we’d have extremely restricted flight potention from the surface. So, it’s an interesting thought experiment to consider it as a proto-sphere, perhaps.

  3. The concept of the Dyson sphere was thought of first by Olaf Stapledon (as Dyson freely admits) in his “Starmaker” story (http://books.google.com/books?id=e2ah-AYb_MAC&printsec=frontcover&dq=Starmaker). Interestingly enough, in the story itself Stapledon writes about a ring of material to capture sunlight, not a sphere.

    As far as the geostationary arc goes, if you work it out there’s on average of 1 satellite per degree of longitude, but the density is not uniform (higher over the US than over the Pacific ocean for example). Right now, I’m trying to increase the density of that ring .

  4. Yes, you are right about Stapledon’s first concept of the sphere. I think that concept of the ring is what I first thought of when I saw the ESA image.

  5. What would be the details of a station that uses solar sails to hover above the sun at a distance to experience one g of suns gravity. How large would sails need to be per kg of station mass
