Well, if this really is a solution, would people take it to mean that it would be okay to still dump ridiculous amounts of carbon in the air? I'm not sure how I feel about that: about taking out any need for a sense of responsibility toward the planet, if that's what this would do. But I am intrigued by any kind of carbon extraction plan.
