    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'?
