UNIST Inverse-L Photothermal Solar Evaporator¶
Membranes & Advanced Filtration • Est. CapEx: Low-cost / Locally fabricated
Technical Overview¶
Researchers at UNIST created a passive solar desalination device featuring an inverse-L-shaped evaporator constructed from lanthanum-strontium-manganese oxide photothermal material. It generates 3.4 liters of potable water per hour from seawater without any external electricity.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | Membranes & Advanced Filtration |
| Capital Cost | Low-cost / Locally fabricated |
| Primary Mechanism | La0.7Sr0.3MnO3 absorbs broadband solar radiation and converts it to heat at the evaporation surface. The inverse-L geometry continuously wicks water upward while gravity and the structure’s geometry channel precipitating salts away from the hot zone, preventing clogging. |
| Target Scale | Household / Village Cluster |
| Standard Lifespan | 10 - 20 Years |
