  1. Modular System Human Powered Providing Basic Needs for Developing Countries Dustin Drake, Alfonso Liguori, Jeremy Smith Florida Atlantic University Department of Ocean and Mechanical Engineering

  2. Human Powered Modular System • Purpose: • Create a device capable of providing basic needs to people in developing nations at a relatively low cost • Focus: • Water purification is most important feature • Additional modules enhance the benefits of the water purification system • Low cost

  3. Human Power Supply

  4. Human Power Supply • For long duration / low intensity operations • Human input = 0.1 hp • Very sustainable for a healthy person • Short duration / low intensity operations will not overly tire the operator • For Short duration / high intensity operations • Human input = 0.2 hp • Sustainable for durations less than 3 hours • Will leave the operator very tired after extended operation

  5. Human Input Mechanism • Goals: • Simple, natural motion • Efficient transfer of mechanical energy • Design Criteria: • Portable • Rigid Construction • Multiple gear ratios

  6. Modules • Water Filtration • Electricity Generator • Irrigation Pump • Millstone

  7. Reverse Osmosis • Purifies water • Highly efficient • Relatively low cost • 4 stages of filtration • Sediment filter • Activated carbon filter • RO membrane • Activated carbon filter

  8. Numerical Analysis • Power requirement: P = Q*p (P: Power, Q: volumetric flow rate, p: pressure) • p = 100 psi • Q = 19 gal/hr • P = 0.019 HP

  9. UV Purification • Disables reproduction of microorganisms • RO system filters out • Most effective at 253.7 nm wavelength • Different microorganisms require different intensities • Average approx. 30 mJ/cm2 • Power required depends on exposure time affected by: • Size of bulb and pipe • Flow rate of water

  10. Electrical Generation Module • Goals: • Charge various types of batteries up to 12V • Provide a source of low current DC electricity for high efficiency light sources (LED based) • Design Criteria: • Human input = 0.2 hp • Expected efficiency = 30% • Expected output = 4 Amps (for 12V)

  11. Irrigation Module • Goals: • Obtain unfiltered water • Irrigate a small field • Design Criteria: • Flow Rate, Q = 5 GPM • Well Depth = 100 ft • Human Input = 0.18 hp • Reliable • Long pump life • Simple to maintain

  12. Grist Mill Module • Goals: • Grind grain • Design: • Must accept various types of grain • Must be able to provide different levels of grind fineness: • Fine grinds for flower • Coarse grinds for cornmeal

  13. Conclusion • This product is design for use in developing countries • Expected final cost
