A competition was held among 43 students from the MSc in Energy and Environment, City University of Hong Kong, to design and build the most effective vertical axis wind turbine (VAWT). The competition, as part of the course SEE6101 Energy Generation and Storage Systems, was organized to enhance hands-on experience and promote creativity among the students. The course aims to educate students on the basic principles of energy supply, from fossil fuel, combustion, power plant to renewable energies such as wind, tidal and solar.
In the competition, the students used scrap materials to build the wind turbines. Their masterpieces were judged based on cost, style and performance, where the VAWTs were placed in front of a fan to measure the rotation speed. Simplicity was the key, but at the end of the day, potato chips, cup noodle, beer and Red Bull are probably the students’ favourites.
