Save The Environment - Build A Skyscraper

Quote:
Italcementi, which spent 10 years developing its TX Active, said the building material is capable of reducing urban pollution by more than 40 percent, the Italian news agency ANSA reported Tuesday.

Tests on a road near Milan showed TX Active cut the level of nitrogen dioxide and carbon monoxide by as much as 65 percent.

It functions via a chemical process called photocatalysis, whereby sunlight triggers a chemical reaction when titanium dioxide on the surface of the cement comes into contact with pollutants in the air. TX Active works most effectively in bright sunlight.

Italcementi said test results have been verified by independent bodies like the National Research Council.

TX Active cement has already been used on a number of buildings, including Air France's new headquarters at Paris' Charles de Gaulle Airport, Rome's Dives in Misericordia church and Bordeaux's Hotel de Police.

Cool, so the Mafia can use it to do something good at the same time they do something bad


A Polish bus manufacturer also developed a new filter system that makes the exhaust gases cleaner than the air in the city.

Improvements come slowly, but surely

They will come much quicker as these new material engineering techniques come into play.

But will they be quick enough to stop what damage we've already set in motion?

I think they will smooth it. That's all they can do.

We've been doing it for over a century, we are not on the precipace of disaster; were already there - we take our hands off at some point and nature will do the rest, sure we will have lost a few species but we will have a whole new diverse set like that in another few million years.
