This Giant Wind Wall Sucks Carbon Dioxide Out of the Air

By turning the CO2 into fuel, it recycles environmental pollutants.

Carbon Engineering has an ambitious plan to take carbon dioxide out of the atmosphere and turn it into fuel. The company is aiming the facility at areas where reforestation isn't an option, such as deserts.

Air flows in through the series of fans you see in the picture, which feed into a carbon dioxide rich solution, helping pluck carbon compounds from the air. That solution is then purified, at which point Carbon Engineering extracts the carbon dioxide for reuse or disposal in underground facilities. The solution is re-purified in the process, enabling it to be reused.

The technology is based on the same way that trees capture CO2 and release oxygen. It's another take on the idea of an artificial tree, one of the potential geoengineering solutions that has been around for years, proposing to fight climate change by hacking the planet.
