Core Concept & Objectives

(Some numbers reflect a pilot with 1 m² WetWalls,

while others should be valid regardless of scale)

Desalination with a Multi-Product Solution

A single system that transforms seawater to atmospheric humidity into:

Potable water via adiabatic cooling and condensation
Geothermal heating & subsurface irrigation through SteamTubes
Salt as byproduct from recirculated water
Humidified cooled air for greenhouse applications

Design Philosophy

Passive operation with minimal energy input
24/7 functionality through day/night mode switching
Zero waste circular resource utilization
Modular scalability from pilot to industrial scale

2. Thermodynamic Innovation: The Parallel Stream Revolution

The Three-Stream Architecture

Much of CONDENSA's effectivness lies in its parallel processing of air streams:

Stream 1: Wet Wall Cooling

Process: Adiabatic cooling
Output: 21°C, 100% RH cold saturated air
Absolute humidity: 0.0156 kg/kg

Stream 2: Solar Collector Heating

Process: Solar thermal evaporation
Output: 48°C, 90% RH hot humid air
Absolute humidity: 0.0770 kg/kg

Stream 3: Fusion Chamber Optimization

Process: Intelligent stream mixing
Output: 33°C, 96% RH optimal condensation conditions
Key: Maximizes droplet formation potential

+ Post-Harvest Reheating - Additional solar heating AFTER water harvesting

Process Flow:

Water Harvest (30°C, 70% RH) → Reheating (35-45°C, 53% RH) → SteamTubes

Thermodynamic Advantage:

Warmer input to SteamTubes (35°C vs previous 30°C)
Greater temperature drop in subsurface cooling (35°C → 26°C)
Lower starting RH (53%) but same absolute moisture content
Result: Enhanced condensation in SteamTubes

Performance Impact with Post-Harvest Reheating:

Additional yield: 25.7 L/hour → ~617 L/day extra irrigation water
SteamTubes output: Now reaches 26°C at 75% RH (optimized for plant uptake)
Total system enhancement: ~530 L/day additional water delivery to soil

3. 24/7 Operation: Dual Mode System

Day Mode (Solar Available)

Primary Path: Water Harvest → Reheating → SteamTubes → Geothermal + Irrigation

Primary product: Drinking water from main condenser/wet walls
Secondary product: Subsurface heating and watering
.. then. Humidified cooled air to greenhouse/living spaces and salt
Energy source: 100% solar passive and fans

Night Mode (No Solar)

Primary Path: Water Harvest → Coconut Mat Module → Greenhouse/Living Spaces

Coconut Mat Module:

Acts as humidifier and mild cooler
Increases RH by 20-30% in greenhouse environments
Lowers temperature by 2-3°C
Ideal for tropical plants and cuttings
Creates perfect propagation microenvironment
Energy source: Fans

(Less yield regarding drinking water, and irrigration.)
