EcoGeek reports that a new startup called Carbon Sciences is proposing to make chalk out of excess carbon dioxide, preventing the CO2 from going into the atmosphere.
Their idea is to turn the CO2 into chalk, or calcium carbonate, which is used in toothpaste, yogurt, PVC piping, paper, wallboard and many other things.
Click over to my new favorite blog EcoGeek for more details and an interview with the founder of Carbon Sciences.
