Sunday, November 19th, 2006
Just when Al Gore was starting to get the message thtough that we need to build more trees… now we’re told we need t build more concrete towerblocks…
from Slashdot: “With concerns over [0]global warming and pollution control reaching an all-time high, an Italian company has developed an interesting solution. It is called TX Active: [1]a concrete that literally breaks down pollutants in the air. The effects are significant: ‘In large cities with persistent pollution problems caused by car emissions, smoke from heating systems, and industrial activities, both the company and outside experts estimate that covering 15% of all visible urban surfaces (painting the walls, repaving the roads) with products containing TX Active could abate pollution by up to 50%.’ Even more significant is that the cost is only 30% over that of normal concrete. Remarkable.”
