The economy may be creeping along at a snail’s pace, fueling the argument for more federal stimulus, but private money is still flowing quickly and quietly into innovative construction materials that promise to help stretch infrastructure budgets and save the planet at the same time. One such venture is Los Gatos, Calif.-based Calera Corp., which soon is to formally announce big plans to capture carbon emissions from coal-fired power plants and lock them up in concrete, the most consumed material on the planet, besides air and water.
