Turning CO2 into sustainable concrete

    The production of cement, which when mixed with water forms the binding agent in concrete, is one of the biggest contributors to greenhouse gas emissions. In fact, about 5 percent of the planet's greenhouse gas emissions comes from concrete.
    A team of interdisciplinary researchers at UCLA has been working on a unique solution that may help eliminate this. Their plan would be to create a closed-loop process: capturing carbon from power plant smokestacks and using it to create a new building material -- CO2NCRETE -- that would be fabricated using 3D printers.

    That 'new substance' CO2NCRETE for those who cannot figure it out, is chalk, or in a fancier form, marble. So they are going to 3D-print this stuff into something wonderful? Cheaply?
    One further factor to ponder, is to ask how lime, a key ingredient in the proposed 'solution', is actually made on a commercial scale: http://lime.org/lime-basics/how-lime-is-made/
    The less dull at SF should be able to figure out the irony. This is not one more government funded insanity passed off as 'a viable greenhouse gas reduction initiative'?
