    1. 1. Renewable EnergySustainable Solution for Local Communities along Thai/Burma Border<br />ECHO Asia Agricultural Conference<br />Chiang Mai, Thailand<br />23rd September, 2009<br />www.bget.org<br />
    2. 2. Do you want to see more of these?<br />
    3. 3. …or these?<br />
    4. 4. What Can We Do to Help at the Regional Level?<br />
    5. 5. Solar Cooking<br />Community Small Hydro Power<br />Renewable Energy<br />Solar Electric System<br />Biogas for Cooking<br />Hydraulic Ram Pump<br />
    6. 6. Types of Solar Cookers<br />Panel Cooker<br />Box Cooker<br />Parabolic Cooker<br />
    7. 7. Solar Cooker: Advantages<br />Easy & simple<br />Save money on cooking fuel<br />No smoke: less respiratory disease<br />Fewer accidents from fire<br />Reduce the use of wood or charcoal -- reduce de-forestation<br />Reduce CO2 emission<br />
    8. 8. Solar Cooker: Drawbacks<br />Cannot be used to cook breakfast<br />Less usable in cloudy or rainy weather<br />Slow heat source means longer cooking time<br />
    9. 9. Solar Cooking Training<br />
    10. 10. Micro-hydro Power<br />Power= 5 x Heightx Flow<br />Height<br />meters<br />Watts<br />liters/second<br />Source: Inversin, A. R. (1986). Micro-Hydropower Sourcebook.<br />
    11. 11. How to Measure Height<br />Direct Measurement<br />Measuring Tape & Inclinometer<br />How to Measure Flow<br />Area or Float Method<br />Bucket Method<br />
    12. 12. Direct Height Measurement<br />A friend<br />carpenter level<br />stick of known height (1 or 1.5 meters)<br />notebook<br />Head = (No. of Sticks x Length of Stick) + Final Measurement<br />
    13. 13. Measuring Tape & Inclinometer<br />measuring tape<br />inclinometer<br />
    14. 14. Measuring Tape & Inclinometer<br />
    15. 15. Area or Float Method<br />Flow Rate (m3/s) = Cross-sectional area (m2) x Float length (m) <br />/ Float time (s)<br />Then change the unit from m3/s to liters/s by multiply by 1,000<br />
    16. 16. Bucket Method<br /><ul><li>50 liter or larger bucket
    17. 17. Stop watch</li></li></ul><li>Suitable Site?<br />Example:<br /> 20 m Head<br /> 15 l/s Flow<br />Power= 5 x Heightx Flow<br />(Watts) = (meters x liters/second)<br />Power = 5 x 20 m x 15 l/s<br /> = 1,500 Watts<br />We want to use less than 50% of dry season flow.<br />So, this site should be able to provide up to 750 Watts<br />
