A new "world's largest" vacuum designed to remove climate pollution from the air has just been unveiled. Here's how it operates.

Clime-works unveiled Mammoth, the world's largest direct air capture (DAC) plant in Iceland, utilizing geothermal energy to remove carbon from the atmosphere. Partnering with Carbfix, it aims to sequester captured carbon underground permanently. Mammoth can annually extract 36,000 tons of carbon, albeit at a cost of around $1,000 per ton initially. Despite its potential, critics question the efficacy and environmental impact of DAC technology. While Clime-works plans to scale up, global carbon removal efforts still fall short of required targets. Other DAC projects, like Stratos in Texas, face scrutiny for potential ties to fossil fuel interests, contrasting with Clime-works' independent stance and ambitious expansion plans.
