AMAZING New Green Technologies in the Works

The world is feeling the effects of climate change. Storms are getting stronger, weather patterns are changing, food is becoming scarce, and animals are going extinct at an alarming rate. Fortunately, while there are many people that are continuing to hurt our environment, there are also people out there who are working feverishly to help it. From simple ideas to entire Eco-cities, new ideas are being developed everyday to help improve the environment and our lives.

Air Purifying Roof Tiles

A big problem with green technology is making it as practical as it is useful. With this in mind, a new trend in practical green technology is the coating of roof tiles with titanium dioxide, which is useful in cleaning the air. Titanium dioxide works as a photocatalyst by oxidizing nitrogen oxides and volatile organic compounds into soluble nitrates and fatty acids when exposed to UV light. Studies have shown that a thick coating of material on roof tiles reduces 97% of target greenhouse gases, while a thinner, cost effective coat still reduces the target gases by 88%. This means that it could cost just five dollars to coat an entire roof with the purifying compound. One home could remove 21g of nitrogen oxide a day, which is the equivalent of what a car releases driving 18,000 km. Widespread application would allow every home in the world to become a mini-air purifier. The idea is still in the testing phase, but early results have been extremely promising. The lighter color of the tiles also has the added benefit of producing a small cooling effect. There’s also a possibility of producing tiles to remove carbon dioxide, but this would decrease the practicality of the tiles by making the roofs harder to install.

Smog-Eating Buildings

Mexico City’s Manuel Gea Gonzalez Hospital constructed a 2,500 square meter facade that breaks down air pollutants when exposed to UV light. The honeycomb increases the surface area by 200% and allows the structure to neutralize the same amount of pollutants in one day that’s produced by 8,750 cars.
