In the report there are electrical systems schematic, it need to be fixed because it is wrong. Also it’s need to be professional not hand drawing. I need to understand and fix it in a good way and add another information if you can. PleAsk me any questions if you have.

Project Description:
Design and build a low noise emission spiral wind turbine capable of generating 500 Watts.
Goals:
1. Produce a vertical axis wind turbine that generates 500 Watts.
2. Build a durable wind turbine that is safe for nearby pedestrians.
3. Create an efficient airfoil design to work at high wind speeds and maximize energy
generation.
4. Develop an acoustic data acquisition system to measure output noise.
5. Integrate data acquisition system into turbine.
Constraints:
1. The device generates at least 500 watts.
2. The noise of emission is below the local noise regulations of 55 dB.
3. The height and diameter meet the customer’s needs.
4. The weight of the turbine meets the customer’s needs.
5. The location of the turbine is free from obstructions from foliage around the building.
6. The materials used are weather proof and do not rust.
7. The design is aesthetically pleasing.
8. The structure and design of the blades function effectively.
