Self-energy sustainable playgrounds for children

A new study is proposed for converting human energy found in children's playgrounds and public place where swings, sea-saw, merry-go-round, and similar types of rides are found. During holidays and vacations, large number of children and adults visit amusement park for fun and enjoyment. The energy consumed by them can be converted into useful energy by modifying the existing rides such as swings, sea-saws, slides and merry-go-round in a way that the playful energy is converted into electrical energy that should be sufficient to light up the park and other small appliances used in the playgrounds. The proposed method can be easily adapted in existing rides and can save energy in emerging countries. The idea of this concept is to develop a culture of green energy from basic mechanisms. The paper is based on the theory behind the proposed method.
