Materials:①8 same size empty bottle
Life cycle Analysis: We use the 8 same size empty bottle like Coca Cola plastic bottle to make the blade of the fan.After we finished the drink,we kept it away.We collect the empty bottle.Similarly,the bottle caps are from the empty bottle.The wood sticks are from the furniture,sometimes the wood of the furniture get down.Then we use it,after this,we can still keep it to do another things.We can use small bulb that only previously replaced. All materials are all from our life.
First, we found 8 coke bottle to cut the top of the bottle as a wind blades. The larger the open area, the greater the tension. The wind energy will be better .
Secondly, we use some glue to stick up the two caps.
Thirdly, we use the cap of the bottle to make the fixing deceive. A bottle is finished the important part. We use glue to stick two caps, the caps for fixed blades. This will make two blades more stable that no easy to brow off by wind.
Fourthly, make two lighter planks overlap and vertical.
Fifthly, we put the generator,connect with the blades.(We can also use gear acceleration deceive. )
Sixthly, we can use the wind drives make the motor to generate electricity.Then we will make a stable wooden cross to support the technology. Because wood is very stable and anti-skidding, so we choose to use the stick slip.
Finally, we will do a very lovely shape ---Robot.
We according to tips from the Internet.We use the Coca Cola plastic bottles as the blades of the fan. Because the the empty bottles as possible as light to make. We use the wood stick instead of the metal stick because it is lighter than metal and it cheaper than metal.
