John Harrison is the managing director of TecEco Pty. Ltd and was published in New Scientist magazine in 2002 for inventing magnesium cements that set by carbonation. In this short movie he discusses Gaia Engineering and his new N-Mg process for producing synthetic carbonate that he plans to use to make not only his companies cements but aggregates as well.
By making all of concrete a carbon sink the sequestration possible is enormous and enough to solve the problem of global warming.
This is the second version of the short Gaia Engineering video.
