Transcript of "Appropriate light"

  1. 1. Appropriate Light in Developing countries<br />TakuroHaraguchi<br />
  2. 2. Agenda<br />Why FabLab?<br />Final Project<br /> -Problem consciousness<br /> - Concept<br /> - Fabrication<br />
  3. 3. Why FabLab?<br />
  4. 4. 1.Sympathywith vision.<br />Just giving product might not work well when it broken or reach life time. <br />But sharing information how to make it will work. This is what I learned in Kenya.<br />
  5. 5. 2.Lack of skills.<br />When I tried to repair solar lanterns which are broken, but I could not do it because of lack of skills.<br />
  6. 6. Final Project<br />
  7. 7. Problem consciousness<br />In a village where there is no electrify in Kenya, people use kerosene lamp. <br />But there are disadvantages.<br />Emitting toxic smoke<br />Risk of fire<br />Running cost to buy kerosene<br />
  8. 8. Problem consciousness<br />Solar lantern could be alternative light by solving issues. But, still there are points to be improved. <br />Once it is broken or reach life time, you have to get another one. <br />Also, poor can afford to buy it because of high price<br />
  9. 9. Concept<br />Appropriate light that people in village can make it by using local available materials and tools.<br />
  10. 10. Fabrication- Dynamo lantern-<br />Generation<br />Lantern<br />Battery<br />Solar lantern<br />Dynamo lantern<br />
  11. 11. Fabrication- Dynamo lantern-<br />Generation<br />Lantern<br />Battery<br />Solar lantern<br />Parts of generation, PV panel, and battery, H-Ni battery(Ni-CD battery), are expensive and it is not easy to get it at even in town. We need to think alternative way to meet the concept.<br />
  12. 12. Fabrication- Dynamo lantern-<br />Generation<br />Lantern<br />Battery<br />Dynamo lantern<br />To meet the concept, I would like to start to think to use dynamo as a generation and lead acid batteryas a battery<br />
  13. 13. Generation<br />There are so many people who do business with bicycle. <br />
  14. 14. Generation<br />It is effective to charge battery during the period of working <br />
  15. 15. Battery<br />There are so many motorbike in a village, so that lead battery is available there.<br />
  16. 16. Battery<br />There are batteries(worn-out battery) that can not work for motorbike but work for LED Lamp <br />
  17. 17. Battery<br />A box in which a battery is put inside is set in front of bicycle. <br />
