To improve tidal locking if that's what you want: Incorporate a long tether (maybe 5x the length of the station) with a big mass at the end, on the side f... |

Thread: Penumbra Station
Post: RE: Penumbra Station
| Reading the last batch of comments here, I see some very valuable feedback. First, let me cover some of the sun-shading physics, as per stevebowers comments.
Why 1 degree? Because that's roughly th... |

Thread: Penumbra Station
Post: RE: Penumbra Station
| This doesn't work well with less-than-perfect orbits, because the angle of the penumbra is on the order of 1 degrees (although it depends on where you are). So I lack any idea of how a non-circular or... |

Thread: Penumbra Station
Post: Penumbra Station
| I want to put out there an artificial mega-structure concept. Specifically, a design that would be an attractive option for civilizations between around 1.0 and 0.75 on the Kardashev scale, who get en... |

Thread: Gravity Balloons
Post: RE: Gravity Balloons
| This is so cool! Amazing illustration.
You went a bit of a different route than I had in mind. I think it's worth looking at, where you start with a liner, inflate it, and then add rocks around it ... |

Another thought: compression.
The idea of a gravity balloon is that the weight of the shell is balanced against gas pressure. Something I ran into with Hawkin... |

I like the self-gravitating approach to resisting 1-bar of pressure.
Instead of the many layers of flow dividers, you could just use a single-layered, closed al... |

Post: RE: Gravity Balloons
| I had overlooked Orion's Arm. Although I knew of it from the self-gravitating ring concept, I never found any direct precedents for what I wrote about in the blog, but the Ederworld page really did h... |
