Solar Domes at Pine Ridge Reservation

Main summary

Key takeaways

Science and Nature

Scientific concepts, discoveries, and nature/nature-adjacent phenomena

  • Off-grid solar power system design
    • A battery-based solar setup intended to enable homes to be “completely off the grid.”
    • Core components:
      • Battery bank
      • Charge controller
      • Inverter
    • Intended outcomes:
      • Power for essentials like lights
      • Support for broader home services (described as “power and water”)
  • Net Zero (“Zero energy”) dome dwellings
    • Solar paired with dome housing to support net-zero living.
    • Framed as “Net Zero Dome dwellings.”
  • Highly efficient thermal building envelope / insulation
    • Traditional housing is described as poorly insulated, with:
      • Earlier mobile home (“cracker box”) construction using thin walls
      • Resulting in extreme cold
    • Dome construction uses cellular concrete described as ~80% air, implying:
      • Strong thermal insulation (reduced heat transfer)
      • Structural capability as part of the dome’s building system
  • Construction/materials science: cellular concrete timing and curing
    • Process described:
      1. Pump “cellular concrete” into the dome structure
      2. Wait for it to dry
      3. After approximately ~14 hours, the structure is described as ready/stable
    • Emphasis: building a hyper-efficient structure suitable for solar integration
  • Energy burden and sustainability economics
    • High heating costs are highlighted:
      • Homes reportedly heat with propane
      • Approximate cost: $500/month (noted for shared households)
    • Solar + efficient housing is presented as reducing these costs:
      • “savings are going to be tremendous”

Project / methodology outline

  • Goal
    • Build and install solar-enabled dome homes on the Pine Ridge Reservation.
  • Per-home approach
    • Integrate off-grid solar components in a sequence:
      • Solar generation → charge controller → battery bank → inverter → home electricity
    • Construct the dome using cellular concrete (noted as ~80% air) for improved insulation and structure
  • Production / rollout
    • Red Cloud Renewable will build 22 small dome homes.
    • Timeline references:
      • Homes expected “by fall of next year”
      • Additional notes suggest readiness by early 2024
