A prototype of a “mechanical tree” developed by Fulton Schools Professor Klaus Lackner and his team in ASU’s Center for Negative Carbon Emissions is featured in a special new exhibit at the Science Museum in London. The exhibit titled “Our Future Planet” focuses on emerging technologies designed to mitigate the potentially threatening environmental impacts of climate change. One of the major ways being proposed to meet that goal is cleaning carbon dioxide from the air, and thereby preventing dangerous levels of the troublesome greenhouse gas from continuing to build up in the atmosphere. Lackner’s mechanical trees mimic the ability or real trees to absorb carbon. The exhibition highlights other engineered approaches to climate control, which could supplement natural processes that help maintain environmental health.
