🔍 SayPro Research and Development Plan
To Validate: SayPro AquaHarvest – Smart Atmospheric Water Harvesting System
1. 🧪 Scientific Feasibility Study
A. Atmospheric Water Harvesting (AWH) Potential in Target Regions
- Objective: Determine if humidity and fog/dew conditions in SayPro priority areas (e.g., semi-arid parts of Southern Africa) are suitable.
- Actions:
- Analyze historical relative humidity and dew point data using meteorological databases (e.g., SAWS, NOAA, World Bank Climate Portal).
- Identify target regions with average RH > 60% and regular fog/dew occurrence.
- Use satellite tools (e.g., NASA POWER) for localized climate models.
B. Material Selection and Testing
- Objective: Identify the best mesh material for fog and dew collection.
- Materials to test:
- Polypropylene mesh (traditional fog nets)
- Nano-coated polyethylene with hydrophilic/hydrophobic patterns
- Graphene oxide and silica-based coatings for enhanced condensation
- Testing criteria:
- Water yield (liters/m²/day)
- Durability under UV exposure
- Cost and availability in local markets
C. Scientific Prototyping
- Build 3 small-scale test units with different mesh types and geometries (vertical net vs. funnel design).
- Deploy prototypes in controlled outdoor environments for 30–60 days.
- Measure daily water yield, evaporation rate, and material wear.
2. ⚙️ Technical Feasibility
A. Solar and Power Requirements
- Assess minimum solar wattage needed to power sensors and small fans (if active cooling is used).
- Choose efficient low-power microcontrollers (e.g., ESP32, Arduino with GSM/Lora).
- Test energy output from small PV panels (10W–30W) in SayPro regions.
B. IoT Sensor Integration
- Test DHT22 or BME280 sensors for humidity and temperature.
- Use flow meters (e.g., YF-S201) to measure collected water volume.
- Test data transmission via:
- GSM (2G) for rural areas
- LoRaWAN for community mesh networking
- Build a simple mobile dashboard (React Native or Android Studio prototype) with:
- Water collection graph
- Maintenance alerts
- Weather prediction integration via open APIs
3. 💰 Economic and Social Feasibility
A. Cost Analysis
- Estimate cost per unit at pilot scale (1–10 units):
- Frame: $10–20 (recycled aluminum or PVC)
- Mesh material: $5–10/m²
- Solar panel + battery + controller: $25–50
- IoT sensors and microcontroller: $15–30
- Total estimated cost: $80–120 per unit
- Explore bulk procurement and local manufacturing to reduce costs by 30–40%.
B. User Acceptance and Usability Study
- Conduct surveys and interviews in target communities to understand:
- Water needs
- Attitudes toward new technologies
- Willingness to maintain and co-own units
- Engage SayPro Youth Clubs in co-design sessions using participatory development tools.
C. Training Program Prototype
- Develop a 1-week training module:
- Basic science of AWH
- IoT assembly and troubleshooting
- Environmental maintenance (cleaning, optimization)
- Pilot the training with 10 youth leaders and gather feedback.
4. 📊 Pilot Evaluation Framework
KPIs for Feasibility Pilot (over 3 months):
| Key Indicator | Target Value | Measurement Tool |
|---|---|---|
| Daily water yield | ≥ 10L/unit | Flow sensor log |
| Cost per liter | ≤ $0.05 | Cost divided by yield |
| System uptime | > 90% | Sensor data logs |
| Youth engagement | 80%+ satisfaction | Post-training surveys |
| Maintenance frequency | ≤ 2/month | Manual check logs |
5. 📍 Partnerships for R&D Support
