Researchers at the University of Georgia have created genetically-modified bacteria that take carbon dioxide from the atmosphere to make carbohydrate chemicals. (Note that hydrogen gas was added for the experiment.) From the article: “We can take carbon dioxide directly from the atmosphere and turn it into useful products like fuels and chemicals without having to go through the inefficient process of growing plants and extracting sugars from biomass.”
I am a firm believer that technology can solve many of our problems. And this, should it prove to be economically viable in large scales, is a good example of just that.
