Black Crocheted Solar Absorber for Water Purification¶

Desalination & Distillation • Est. CapEx: $3.50 USD • Lifespan: 7–15 Years

Technical Overview¶

A novel, low-cost solar evaporator made from black crocheted yarn with a superhydrophilic coating. It efficiently evaporates contaminated water, leaving pollutants behind, and is made from affordable materials.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Desalination & Distillation
Capital Cost (CapEx)	$3.50 USD
Power / Energy	Solar PV / Thermal
Target Scale	Community Scale
Standard Lifespan	7–15 Years
Technology Maturity	Prototype
Primary Mechanism	The black crocheted structure absorbs sunlight and converts it to heat. Water wicks through the hydrophilic yarn and evaporates from the heated surface, while contaminants remain in the bulk water. The condensed vapor is collected as purified water.
