Scientists from the University of Calgary in Canada have created a method to efficiently capture carbon dioxide directly from the air around us. The device, which is built on near-commercial technology, was built by Uof C climate change scientists David Keith and his team.

“At first thought, capturing CO2 from the air where it’s at a concentration of 0.04 per cent seems absurd, when we are just starting to do cost-effective capture at power plants where CO2 produced is at a concentration of more than 10 per cent,” says Keith, Canada Research Chair in Energy and Environment.

“But the thermodynamics suggests that air capture might only be a bit harder than capturing CO2 from power plants. We are trying to turn that theory into engineering reality.”

What’s riding the rails in your hometown? A few hobos maybe, but also potentially deadly chemicals rumble through America’s communities daily. My hometown paper, The Galesburg Register-Mail, printed a series of articles on the dangers nearly every train brings to a community. And in Galesburg, IL, this is particularly important: approximately 1,000 cars travel through the city daily on two major railroads that cross town, the Burlington Northern and the
