An Italian company has invented a cement that breaks down pollutants in the air. We need more innovations like this.
Slashdot blog says:
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.”
For even more info, Business Week has an article.
