Week 15

Title : New Concept

Objectives : To test new concept about wind turbine

Contents : I had opened a webpage regarding my wind turbine design.. and I had found out something amazing.. The blogger used a plastic bottle to make a wind turbine.. The steps to do it are very simple but interesting.. Therefore, I decided to give it a try..

Results : After get a rough time cutting the bottle to get a good shape, I had made 2 bottle that can turn when the wind blow..

 for the white bottle, i had made it to open outside from the bottle.. so it can attract the wind.. for the green bottle, i had made it to open inside, and the results are more better than the white bottle..

this is the closer view of the green bottle.. i put the sellotape to make sure that the position of the bend side are hold in it position..

i made a hole at the cap of the bottle, and put a wire through it.. and it turn smoothly with slow wind.. but unfortunately, it is not suitable for my project.. this is because, when the wind blow, the bottle also swing, and it reduce the turn of the bottle..

Conclusion : i need to make a new design for my project.. i cannot proceed with this design because of the swinging of the bottle.. i had put some weight at the bottom of the bottle, but it just slow it down.. so the next entry, i will show u all my new design..
