mikelepage: Helical Space Habitat (HeSH, 2014)

Design summary

  • Structure. Robot-assembled interlocking bricks (3D printed, or made of regolith) laid in an anti-parallel double helix around a torus. Water pipes run through the bricks for balance and heat distribution. Sun-facing side; sealer pumped in; a Shapeways model was made mikelepage, 2015-03-12.
  • Related thermal ideas. Helical coolant channels in 3D-printed module envelopes; a high-thermal-mass water biosphere for equatorial LEO eclipses; mirrors to simulate a 24 h day mikelepage, 2015-09-06.
  • Broader vision. Large AG habitats need passive shielding and ISRU, built in their final orbit by radiation-hardened robots; a probe that 3D-prints toroids from NEO regolith mikelepage, 2015-02-22. A later "nautilus shell" spiral settlement of regolith cells mikelepage, 2022-09-09.

Critiques raised

Open questions

  • Can printed or sintered bricks hold 1 atm with an acceptable leak rate?
