This statement from the article cautions us that the economic incentives (which are also reasonably well described in the article) so far aren't promoting technical fixes like the one proposed by the inventors: "None of the world’s thousands of coal plants have been outfitted for full-scale capture of their carbon pollution. And if it isn’t economical for use in power plants, with their concentrated source of carbon dioxide, the prospects of capturing it out of the air seem dim to many experts. 'There’s really little chance that you could capture CO2 from ambient air more cheaply than from a coal plant, where the flue gas is 300 times more concentrated,' says Robert Socolow, director of the Princeton Environment Institute and co-director of the university’s carbon mitigation initiative."

When I hear about plans to capture CO2, I wonder immediately about whether those plans will help enough if other gases (for example, methane) play a significant role in greenhouse effects. We may have to sequester more than one gas, in more than one way, to role back the accumulation of greenhouse gases already in the atmosphere, if that is considered a desirable worldwide goal.
