Klaus Lackner

Klaus S. Lackner is the Founding Director of the Center for Negative Carbon Emissions (CNCE) and a professor in School of Sustainable Engineering and the Built Environment at Arizona State University. He is scientific advisor to Carbon Collect Limited, and senior science advisor to Aircela Inc. He is a pioneer in carbon management and is the first to suggest capturing carbon dioxide from air in the context of addressing climate change.

Mechanical trees
Klaus designed the prototype Mechanical Tree (also referred to as a Synthetic Tree or Fake Tree,) which was on display at the 'Our Future Planet' temporary exhibition at the Science Museum, London from May 2021 until September 2022. The technology consists of sorbent tiles which cyclically are extended into the air and then retracted for regeneration. The sorbent tiles passively soak up the carbon dioxide from the air using 'passive direct air capture' (PDAC) technology and are claimed to be 1,000 times more efficient than natural trees that use photosynthesis. Subsequently the carbon dioxide captured can be either sequestered in underground geological formations or sold for industrial use. The PDAC and Mechanical Tree technology has been licensed to Carbon Collect Limited by CNCE. ==See also==
