Laser-Etched Superwicking Solar-Thermal Desalination¶
Desalination & Distillation • Est. CapEx: $5,000 USD • Lifespan: 7–15 Years
Technical Overview¶
A solar-thermal desalination system that produces freshwater from seawater without generating brine waste or requiring chemical pre-treatment. Engineered for coastal regions, the device distills water using sunlight while simultaneously harvesting solid salts and minerals such as lithium.

| Primary Mechanism | Black metal panels are etched with femtosecond lasers to create superwicking, ultra-light-absorbing surfaces. Solar radiation drives evaporation of a thin seawater film across the active region; salts and minerals crystallize on passive untreated sides via the coffee ring effect, preventing clogging and enabling continuous operation. |
