Forests of carbon-capturing mechanical trees could play a big role in helping reverse much of the unhealthy impacts of the massive amounts of carbon dioxide that power plants, industrial processes and automobiles have emitted into the atmosphere since the first industrial age. The tree technology being developed by ASU’s Center for Negative Carbon Emissions, led by Fulton Schools Professor Klaus Lackner, faces challenges to successful deployment. But progress is being made toward optimizing the carbon capturing effectiveness of the system and building prototypes to do advanced testing.
