Yet the cold air blowers consume a ton of energy. But now researchers say they have a solution for these energy hogs that actually helps the climate. In a new analysis, scientists argue for using air conditioning units to capture carbon dioxide straight from the atmosphere and transform it into fuel. The idea is that these renewable-energy powered devices would lower atmospheric CO2 and provide a scalable alternative to oil, natural gas and other fossil fuels.
The conversion tech would first take in CO2 and water from the air. Then, an electric current would ...
