Caveat;
- Thinking about lava sustainability with respect to typical Kilauea pahoehoe type flows at a distance from a vent. Not big aa flows.
Goals;
- Might be to produce "hard" actual survivable in place structures or "semi-hard" structures that could be modified as needed when lava approaches - assume weeks of warning
Starter engineering ideas;
- Build things on concrete bases/columns
- Possibly detachable/expandable at top so that as lava envelops the base, the column can expand vertically
- Utility lines might need to be built with extra line and a tensioner so that top of a pole can be raised vertically without rewiring
- Build structures with mechanical support like jack points on the underside of cars so that as lava approaches, columns can be detached, the structure can be lifted and taller columns locked into place
- Possibly have modules that will mechanically expand upwards as they are heated by lava. Could be permanently in place or deployed as lava approaches.
- Roads (or buildings large enough that they could act as dams) need to be able to pass lava underneath.
- Allow some portions to be fixed/act as dams; intervening portions form channels to point the lava in a given direction as it passes under. Rebuild/repeat for subsequent flows (now we can have a good time talking about whether this is acceptable diversion or lava management if you will)
- Water/sewers
- Bury them very deep underground? How deep do you have to put a water line to keep it from boiling?
- A grid that parts of can be shut off, while other parts keep flowing?
- Build light/modular/removable
- Good for homes, not so much for roads, power, water
