In North Korea's rural areas, many children lack the conditions to study at night due to the power shortage. Rotator can be used as dance props or toys for children, and can also be used as an electric light at night. The kinetic energy generated by shaking the long streamer can be converted into electric energy and stored, and the stored electric energy can be used at night. This concept is inspired by the popular sport of Korean people - Elephant hat dance
