Pham Xuan Tri, a Vietnamese high school student has become famous for inventing a machine that generates electricity from human paces. He has received many great awards like the National Science Fair Award or the Viet Nam Technical development Fund award. He is an enthusiastic teenager with the ambition to improve the living conditions of his neighborhood starting with the idea to create this device. Although, the function of collecting energy from human paces and transforming it into electricity sounds very simple, it took him months of researching and collecting material to achieve this success.
A group of 6 friends, 4 girls and 2 boys, have initiated a project to transfer garbage into building material. In an interview in 2012, they said the idea simply came from their ambition to clean up the living environment while providing better living conditions for people.
