Want cleaner air? This billboard can help.

In Lima, Peru a billboard purifies 3.5 cubics of air a day.

Engineering students in Lima, Peru constructed an air-purifying billboard.                                                                             (www.designboom.com)

From the same Peruvian school that brought you a billboard that produces water, the University of Engineering and Technology (UTEC), now brings you a billboard that cleans 3.5 cubic feet of pollution per day!

The idea for creating an air-purifying billboard came when it was noted that the amount of air pollution in Lima, Peru had increased due to the rapid development of the city.

Taking into account the alarming rate of construction currently taking place in Lima, it makes complete sense to seek a solution that will not only benefit construction workers but also residents who live near the construction site.

Potential health risks brought forth by exposure to highly-polluted environments, such as cancer, make the creation of this type of technology extremely beneficial.

The way the technology attached to the billboard works is by absorbing all the polluted air around the construction site, filtering the air through a water system and returning the purified air to the surrounding areas.

The clean air which is then dispersed, an amount equaling that provided by 1,200 trees, can reach a radius of five blocks.

UTEC’s motto “change the world through engineering” has taken a literal meaning with the creation of projects like this one. UTEC will test their recently concluded project in the construction site of their new campus in Peru’s capital.

By placing the billboard at the center of the construction site, UTEC has been able to simultaneously purify the air while advertising their new campus and engineering efforts.

Pretty brilliant, if you ask me.

Who would have thought that the water cycle taught to us in elementary school could be redacted to meet the needs of humanity in a time where the levels of CO2 have skyrocketed due to the impact of globalization and industrialization?

Can’t wait to see what UTEC has to offer next, any ideas?
