As atmospheric carbon dioxide levels continue to climb, a team of California scientists has created a new material that will help reduce the amount escaping from smokestacks and power plants. The material, called polyethylenimine, or PEI, acts like a carbon dioxide fly-tape trap, attracting the greenhouse-gas molecules and sticking to them so they can't escape. Indeed, carbon dioxide is so attracted to the material that the team says it can pull the molecule right out of the air, something other carbon filter materials have not been able to do well.
