Triple-utility passive solar-thermal concrete system
AeroCement transforms ordinary concrete into multifunctional energy infrastructure:
- ☀️ Solar Capture - Absorbs 95–98% of solar radiation
- 🔋 Thermal Storage - Stores heat for 7+ nights underground
- 🏗️ Structural Material - Load-bearing walls
Performance: ~12.91 kWh/m² nightly | 7-night accumulation = ~82.98 kWh

- Open-cell aerated concrete with zirconium
- Volumetric blackbody: 95–98% absorption
- No separate solar panels needed
- Heated air moves through underground channels
- Thermal labyrinth stores energy in ground battery
- Decouples thermal mass from living space
- Stirling engine or heat exchanger
- ~3.11 kW continuous from 10m² array
- Zero fuel cost, zero emissions
