  2. Micro Hydro Power • Adapted from: • Don Harris • Practical Action • Appropedia • Energy Information Administration

  3. Hydroelectrc is 3%

  4. Most of that 3% is from large hydroelectric plants http://en.wikipedia.org/wiki/File:Sayano-Shushenskaya_hydroelectric_station.jpg

  5. Classification

  6. What does that look like? http://en.wikipedia.org/wiki/File:Gluehlampe_01_KMJ.png

  7. Manicaland Province of Zimbabwe The power of water electrifies remote Andean villages – Practical Action Peru Turgo Turbines

  8. Micro Hydro • Small in scale • Minimum environmental impact • Site specific: you must have the resource • Affordable • Consistent: Produces continuously, 24/7 Don Harris

  9. Types of Systems Classification of turbine types. Source: Micro-hydro Design Manual, IT Publications, 1993

  10. Pelton and TurgoImpulse – jet of water 4 “ Don Harris

  11. Turbines are turned by water. That turning motion drives a generator which produced electricity. Don Harris

  12. The IntakeDiverting clean water into the penstock Screen Steam Flow The intake’s job:Filter and Settle Start of Penstock Build it either:Simple and easy to repairOrBullet-proof Don Harris

  13. The IntakeDiverting clean water into the penstock Steam Flow Overflow A dirty creek may need more settling time Screen Start of Penstock Don Harris

  14. Penstock A full pipe; delivering clean water to the turbine Don Harris

  15. Burying Pipe Burying a pipe line removes the biggest eyesore of a hydro scheme. It is vital to ensure a buried penstock is properly and meticulously installed subsequent problems such as leaks are much harder to detect and rectify. Don Harris

  16. Penstock Support SystemPVC likes to stay straightHDPE can follow the contour of the ground Don Harris

  17. Alternative Power & Machine Economy models Permanent magnet units Accessories Exercise Bicycle Type Battery Chargers, etc. Niche: Ease of maintenance and adjustment www.apmhydro.com Don Harris

  19. Classifications, howtos, equations and follow-ups at: http://www.appropedia.org/Microhydro
