After graduating in Environment Sciences from the Faculty of the Hanoi University of Sciences, I worked for the Institute for Water and Environment, which is affiliated to the Academy for Water Resources of the Ministry of Agriculture and Rural Development. Working for the institute provided opportunities to approach and implement projects on environment assessment and other research. I have finished my Master’s in the area of new energy and the environment.

Our goal is to provide urban Hanoi with gymnastic equipment for public areas, which, at the same time, contributes to the purification of polluted lakes in the city by utilising energy generated from the exercise machines. In some countries, there are currently some model projects which use gym machines to generate energy for other activities. In Vietnam, at the moment, people undertake gymnastic activities only to improve their health. We propose a new model, combining a health improvement initiative with a lake water treatment system to solve our pollution problem. Lakes play an important role in urban spaces, providing areas for people to relax and exercise. However, in Hanoi, lakes have become seriously polluted. Governmental authorities as well as domestic and foreign organizations have invested much in lake water treatment activities but pollution is still very high. At the same time, people's desire for daily physical exercise has increased considerably as living standards have risen.
