Embed code for: The structure of a wind turbine designed with a Coke bottle (2)
Select a size
Part 1 :Problem statement:
Design and build a renewable energy system that can reach and sustain the highest possible voltage.
Man-made fan can rely on wind power by generation.
It should be strong to hold the wind power.
Wind driven fan rotation wind energy into mechanical energy.
We choose wind power generator in order to make an object run.
The principle of wind power generation, the use of wind driven turbine blades rotation, and then through the growth machine will improve the speed of rotation, to encourage generators. Wind power is the formation of a craze in the world, because the wind does not require the use of fuel, but also does not produce radiation or air pollution.
The first wind driven fan rotation wind energy into mechanical energy. The gear drives the impeller to rotate the internal conversion, transmission of mechanical energy.
In wind power generation systems, wind drives turbines that generate electricity. This process has the great advantage of being free from carbon dioxide (CO2) emissions. There are several types of wind turbines. Horizontal-axis three-bladed turbines, which are the main stream for large-scale power generation, can convert about 40% of wind energy into electricity.
Wind power generation has four principal advantages:
Environmentally friendly, involving no emission of harmful exhaust
No oil or natural gas be used
Wind is a natural resource that is not depleted
Positive impacts on industry and employment
Before the research, we wanted to use solar energy to make a fan. Solar Panel are used almost every technological thing. But the teacher told us not to use solar panels. Only with a few small electric things, Like small generator. Then we researched in the Internet, so we changed the solar energy to wind energy. Nest, we took a long time to search the Internet. Because of the wind energy needs the buttery, we got some tips to find the materials conveniently from the Internet. When we find the materials,we should have as far as possible the light materials as fan blade. The length of the support pole will be longer, the effect will be better.
We find a easy one in the internet how to use the wind power into electric energy . The structure of a wind turbine designed with a Coke bottle , The first is a wooden need to fix the entire power generation systems, over the wood bracket is the generator, add a Gear acceleration device is best so that the model can ran faster , and more efficient . take two crossed lighters wooden rods perpendicular to each other and connect with the generator,（The length of the pole should as long as possible, In order to increase the mechanical energy furthest ） The edge of each board was glued a Coke bottle cap in order to fixed the leaves and each leaves made by the first of the half coke bottle,the total of the leaves are four .
There is always a chance of failure in the experiment. so we still find some solution on the Internet to solve the problem. First we can Increase the number of leaves, also we can find some bigger coke bottle, increase the force. Second we can make the wood bracket more longer. Third we can change the variable speed device.
We also search a video from website: http://m.ku6.com/show/sE7lKdbgezRIJ59EkrOUvA...html
Through this video we know how to wind energy into electrical energy through the generator
