Below are a video and pictures of my final product. This model works by converting light energy from the sun into electrical energy (through the wires into the motor), which is then used to power a motor, transforming into mechanical energy. This is done as when the photons from the sun hit the solar panel, it knocks the electrons away from the silicon atoms. The moving flow of electrons initiates a flow of electric current, which then flows through the wires into the motor. The motor transforms electrical energy into mechanical energy by using electric current to turn an axle. This axle is then used to spin a fan, generating the wind.
Some areas I was successful in was generally getting it to work. The velcro would stick together nicely, and worked well. The solar panel was able to be adjusted as planned, so it could be repositioned to face the sun when needed. In my prototype, the wires were free and could get stuck in the fan. To change this, I put a “pocket” for the wire to go through, so that way it wouldn’t get caught in the fan. Some improvements I could make could include a cover for the solar panel, so that way, instead of moving the entire platform, they could just cover up the solar panel to stop the fan as a sort of “switch.” Another thing I could improve would be to make the velcro more secure/clean or find a secondary adhesive, as some of the velcros seemed to not stick as well as other parts for some reason. Also, the solar panel was too weak, so maybe next time find a stronger solar panel that could generate more electricity or find a more efficient fan. If the solar panel was more efficient and the fan could be stronger, it could be environmentally friendly as they could just use renewable energy to keep them cooler, instead of using normal and traditional methods.
