Alain Goeppert, G. K. Surya Prakash, chemistry Nobel Laureate George A. Olah and colleagues have co-authored a paper (doi: 10.1021/ja2100005) in the Journal of the American Chemical Society describing a novel, cheap material that scrubs CO2 from ambient air, even at the very low concentrations of the atmosphere. The material is easily manufactured, and carbon captured is readily removed from the polymer, allowing recycling of the polymer and sequestration of the carbon. The researchers, co-authors of Beyond Oil and Gas: The Methanol Economy regard this as more than simply a technique for decreasing the carbon emissions of industrial processes and fossil-fuel burning machines, but as possibly an energy-carrier, by using the "catalytic hydrogenation of CO2 with H2 where the hydrogen has been obtained from water electrolysis (wiki).

Dirty Coal, Clean Future
To environmentalists, "clean coal" is an insulting oxymoron. But for now, the only way to meet the world's energy needs, and to arrest climate change before it produces irreversible cataclysm, is to use coal—dirty, sooty, toxic coal—in more-sustainable ways. The good news is that new technologies are making this possible. China is now the leader in this area, the Google and Intel of the energy world. If we are serious about global warming, America needs to work with China to build a greener future on a foundation of coal. Otherwise, the clean-energy revolution will leave us behind, with grave costs for the world's climate and our economy. (more here and responses here, here and here)

Does riding a bike really help the environment? Mr. Green at the Sierra Club says don't over think it, but a couple of folks trying to measure the energy cycling uses aren't quite sure. There are plenty of excuses for not to riding your bike, but is there a rationale? If you want a go at calculating this yourself, here's a handy guide to the variables. [more inside]

The average American uses 20 pounds of coal a day. "our shiny white iPod economy is propped up by dirty black rocks.. I see more people dying of particle air pollution than are dying of AIDS." Coal accounts for nearly 40 percent of America's carbon dioxide emissions. Big Coal by Jeff Goodell.

The jolly green Hummer? The growing band of environmental offset companies which give you the chance to offload your SUV driving, energy squandering guilt onto an annual subscription and a fancy bumper sticker looks like one way that we'll be able to live with ourselves in the power hungry 21st century. Is this the placebo we've all been waiting for?

Eprida: using biomass to produce hydrogen, reduce the emissions of coal-fired power plants, and suck CO2 out of the atmosphere, all while improving agricultural productivity. A new virtuous cycle (flash)?
