University of Calgary scientist are working on a machine that would tear carbon dioxide from the air in an attempt to scrub out emissions from diffuse source , such as car exhaust fumes and home heating . These “ diffuse emission ” report for just about one-half of the CO2 that goes up into the sky every day , bestow to planetary warming . The scrubber takes in air and binds the CO2 to atomic number 11 hydroxide . The heavier concoction is then place through a few more chemical intermediaries , finally lead in a pot of part CO2 that can be piped away , while the hydroxide gets fed back into the machine . agree to the university , the scrubbers can enamour around a ton of carbon dioxide for less than 100 kwh of electrical energy , about ten metre as much CO2 as was released to keep it run . Unfortunately , that ’s not quite enough to keep it from being prohibitively expensive . The cheapest way to keep CO2 emissions out of the air is still not generating it in the first place .
