If two scientists at Los Alamos National Laboratory are correct, people will still be driving gasoline-powered cars 50 years from now, churning out heat-trapping carbon dioxide into the atmosphere — and yet that carbon dioxide will not contribute to global warming.
The scientists, F. Jeffrey Martin and William L. Kubic Jr., are proposing a concept, which they have patriotically named Green Freedom, for removing carbon dioxide from the air and turning it back into gasoline.
The idea is simple. Air would be blown over a liquid solution of potassium carbonate, which would absorb the carbon dioxide. The carbon dioxide would then be extracted and subjected to chemical reactions that would turn it into fuel: methanol, gasoline or jet fuel.
This process could transform carbon dioxide from an unwanted, climate-changing pollutant into a vast resource for renewable fuels. The closed cycle — equal amounts of carbon dioxide emitted and removed — would mean that cars, trucks and airplanes using the synthetic fuels would no longer be contributing to global warming.
Although they have not yet built a synthetic fuel factory, or even a small prototype, the scientists say it is all based on existing technology.
“Everything in the concept has been built, is operating or has a close cousin that is operating,” Dr. Martin said.
If it happens....
I like the idea that in 2050 I'm driving around a future car with a real gas engine and the whole CO2 issue ain't even a thought.
So much better than the moralistic anti-growth policies of the doomsayers.
