14 Apr Water out of the air
Right next to the Panamericana Highway in Peru, 89.5 km south of Lima, the Universidad de Ingeniería y Tecnología (UTEC) set up a huge billboard. A billboard that generates drinking water out of the humidity of the air.
Lima is the second largest city in the world, to be located in a desert area (after Cairo, Egypt). The total amount of annual rainfall is very low. However, humidity rates in the area can reach up to 95%.
The billboard consists of 2 special filters: 1 air filter and 1 carbon filter. In between these filters, there is a condenser. The billboard captures the humidity out of the air, and passes the condensed water through the 2 filters, all the way down to a large water tank. At the bottom of the billboard is a tap.
The billboard was set up as a promotional stunt to attract new students for the next academic year.
