A scientist at Princeton University has proposed removing excess carbon dioxide from the atmosphere using ventilators.
No matter how hard scientists try, they cannot stop global warming. Industry and transport are putting sticks in their wheels. Over the past year, about 37 billion tons of carbon dioxide were released into the atmosphere. CO2 is a significant contributor to the greenhouse effect and contributes to global warming.
According to experts, by the middle of the 21st century, 10 billion tons of carbon dioxide will need to be removed from the air annually. Such data were published in a report by the US National Academy of Sciences, released last Wednesday. Biologist Steve Pakala has suggested a way to organize this. Scientist from Princeton University proposes to build huge fan plants with purification tanks. The air pumped into the units will be passed through a special aqueous solution that will absorb CO2.

Pakala proposes installing such fan batteries throughout the United States. A similar air purification technology is used at the Climeworks plant in Switzerland. However, the cost of extracting 1 ton of carbon dioxide in this way reaches $ 600, which makes the technology unprofitable. In order for the CO2 obtained in this way to be used in industry, the cost of 1 ton of gas must be about $ 100.
But the need to save the planet may be more important than the benefits. Greenhouse gas emissions into the atmosphere are constantly growing, and the figures given in the report of the Academy of Sciences may even turn out to be too optimistic. If left unchecked, atmospheric CO2 concentrations by mid-century will be much higher than reported.
