Billboards That Are Actually Good For Something #8

I think it's fair to say that I hate being advertised to. I avoid watching television and watch shows online for less ads, even then I mute them and find something else to do for the thirty seconds they play and I never give magazine advertisements a second glance. I think it's fair to say that I avoid advertisements fairly well. I think of them as necessary but unfortunate parts of life. I know that some websites and companies use them as their only source of profit, like many of the partners of Youtube, which is why they are necessary, now I don't particularly want to be advertised to, but if it brings money to the people that I want to support, then I see no reason why not. Now, a new technology has come to light in Lima, Peru: A billboard that has the technological capability of transforming water vapor into clean, drinkable, water. Basically, nothing short of an absolute miracle.
The billboard works by using the abundant water vapor in the air and the process of reverse osmosis to produce up to 20 liters of water a day. It needs electricity to run this process and it is currently using the power grid of the city, but it could be changed to use solar panels or fuel cells. Unfortunately, this process only works because of the high humidity in the air already in Lima, Peru, which ranges from 83-100%. This high humidity is caused by the city's close proximity to the southern part of the Pacific Ocean. The billboard is specifically designed for a humid city that needs water. Still, if innovative solutions, like this one, can be used to provide water to those who desperately need it, that could end our fear of lacking water for good. I don't think that people would even mind being advertised to on these billboards.
