2.  Main goal  Operation of a windmill  Situation analysis  Process of the project  Conclusion

3. To ensure the self-sufficiency in electrical energy of the technology room. Available equipment :  a 200 Watts windmill

6. Discovery of secondary targets: o Discovery of secondary targets:  to tackle the study of a windmill operation  to measure the capacitance of our windmill  to think about the final results o To think about the constraints we will meet during the project:  to think about the safety in the classroom  to get a low energy production o To find solutions:  to dismantle the blades for the safety  to find an adaptable solution to meet the expected results

7. o To research (windmill operation) o Manipulations (measures, calculations,…) o To look for a system : a crank (for the safety) o New manipulations o Results and solutions

8. The final results are too low (we got around 200W and the total need for the classroom is about 8755W), so we had to find a solution :the total need We decided to take into account only lightings and to use a lighting which consumes less (LED floodlight).LED floodlight Besides, thanks to many windows in the classroom, we don’t have to use any ligthings and we can find a complement with solar panels according to the needs. The lighting can become independent

9. Total need in the ISI classroom Previous
