Klaus Lackner, a professor at the School of Sustainable Engineering at ASU, has been selected by @newsweek as one of America’s greatest disruptors for his revolutionary work in #carboncapture. Lackner first floated the idea of removing carbon directly from the air as a way of putting the brakes on climate change in 1999, and he has been devoted to figuring out how ever since.  The prospect of keeping up with the 33 billion tons of carbon the world releases into the atmosphere each year, let alone removing enough of it to return to pre-industrial levels, is daunting. But the problem's vastness and urgency argue for pursuing every available means. Lackner has worked to develop a mechanical tree that removes carbon dioxide a thousand times more efficiently than natural trees and requires no energy to operate. And in 2021, a Dublin-based tech company, Carbon Collect, got $2.5 million from @energy this summer to build three "carbon farms" of Lackner's trees capable of capturing 1,000 to...
