| | Abstract | The purpose of this experiment is to design and build a model door which |
| | will produce energy. The procedure starts with the design. After the |
| | design was created, then materials were gathered. The actual building of |
| | the door included cutting wood into a base, door, and door frame pieces. |
| | The door was set into the base with a pivot. At the top of the door frame, |
| | a crank flashlight with the crank removed was placed and an all thread |
| | was connected to the flashlight crank housing. The turbine inside the |
| | flashlight turned with the motion of the door as the all thread worked as |
| | the crank creating energy. The data for the project involved finding the time |
| | period when the doors at my school were in use the most. I found there |
| | was an average of 29.38 minutes per day where the doors opened and |
| | closed consistently as students entered and exited the school building. |
| | Using the consumer packaging information, I learned one minute of |
| | cranking was equal to ten minutes of light. Therefore, the motion of the |
| | door would create about 5 hours of energy with the flashlight. I concluded |
| | the motion of the door could create energy to power the exit signs in the |
| | building. |
