Scientists at the University of Engineering and Technology (UTEC) decided to create a billboard that will purify 100,000 cubic meters of air everyday in crowded cities, which is equivalent to the work of 1,200 trees, and its effects reach people within a five block radius. The billboard which uses thermodynamic principles to actively dissolve pollutants in water to release fresh air.
