Marwin is a clever, likable boy of our time. We learn about his birth, his development, and his experiences in kindergarten, elementary school, and high school. Like many, he dreams of a better life, not just for himself, but for all people. Therefore, he engages with the problems of our day. This is not done in a serious manner, but rather in a humorous way, yet it can certainly provoke thought in an interested reader. In the scientific club of the high school, they also want to help tackle the problems of our world and are looking for ways to provide optimal energy supply for people. With the help of Faust, who he encounters multiple times, Marwin develops a device that can generate unlimited necessary energy for every person with minimal effort. This could solve all the energy problems of our world.
