Futuristic carriages purify the air across the country as the train moves

American rail startup CO2 Rail has developed a train car project that captures carbon from

air. Under the plan, the modified wagons will traverse the country, negating the need for large fixed CO₂ removal facilities, according to a press release.

Researchers plan to usebuilt railway cars equipped with large vents where air will enter when the train moves at high speeds. The system will operate on the move, so there is no need for fans that are typically installed in fixed direct carbon capture systems. This will save a lot of energy.

The wagons of the futuristic train will be equipped withchambers to collect carbon dioxide, which will then be concentrated and stored in a liquid tank. Air that does not contain carbon dioxide will be emitted back into the atmosphere from the rear or bottom of the car.
