Question

A team of students built an electric fan. They calculate that the fan’s efficiency is just 46%.
Explain in 3-5 sentences how they could improve the fans efficiency
GPT 3.5
To improve the fan's efficiency, the students could start by using a more efficient motor. High-efficiency motors have lower energy consumption and can convert a higher percentage of input energy into useful work. Secondly, optimizing the design of the fan blades can enhance its efficiency. Utilizing aerodynamic principles such as reducing blade drag and increasing blade pitch can improve the fan's performance. Lastly, the students could also consider reducing friction in the fan's moving parts by using ball bearings or lubricants to minimize energy losses due to friction.
