Despite distance learning, we continue to participate in the project. This week we participated in a videoconference during which engineer Korneliusz Sierpowski, a researcher at the Wrocław University of Technology, told us about wind turbines. We got to know the types of turbines and their construction, and thanks to computer animations we saw how turbines work and how we obtain electricity thanks to them. The engineer conducted an experiment on a vision with a dryer and a wind meter. He showed us which locations are the best for building wind turbines, where there are the most of them in Poland and in which countries clean wind energy is used. Children asked questions to which Mr. Engineer patiently and comprehensively answered. People were asked how to protect the turbines against flying birds (white and red stripes are painted on the blades and deterrent systems are used, e.g. sounds with an appropriate frequency). There were questions about the durability of the "windmill" and whether it can also be used in cities. We already know that the turbine can be built at an appropriate distance from the buildings - at a distance of 10 times the height of its tower. We also saw the stages of building a turbine.
The lecture was very interesting, enriched with animations, films and even an experiment! Although we planned the meeting for about 30 minutes, thanks to the children's questions and answers, the classes lasted twice as long. Thanks to this, we know more about the method of producing clean energy.
