Greater savings come from radically increasing our efficiencies and developing and delivering to market sustainable technologies. However maybe in the future these crystals could help create diamonds with the sequestered CO2 and we could wear our climate change on our sleeves. - richard Davine Thu, 25 Feb 2010 18:19:59 +0100 http://www.ecogeek.org/preventing-pollution/3073-highly-efficient-co2-capturing-crystals#comment-36140 Unless we can work out a way to feed spent crystals to farm animals or otherwise incorporate them into the food chain we are at the risk of these things escaping and re-releasing the CO2. - Eric Wed, 17 Feb 2010 20:13:52 +0100 http://www.ecogeek.org/preventing-pollution/3073-highly-efficient-co2-capturing-crystals#comment-36113 There is no problem finding materials to absorb CO2. The problem is that it costs a lot for the material, then what do you do with it after it absorbs the CO2. It usually costs lots of energy to extract the CO2 and sequester it. You can make fuel out of CO2, H2, and energy, but where do you get the energy and H2? Nothing man-made can compete with biomass in cost. This project seems interesting from a chemical engineering point of view, but I don't see that it would be cost-effective as a CO2 absorber. It's much cheaper to use alternatives to digging up and burning fossil fuel. - Carl Hage Tue, 16 Feb 2010 18:58:09 +0100 http://www.ecogeek.org/preventing-pollution/3073-highly-efficient-co2-capturing-crystals#comment-36108 Convert the Co2 into fuel? I don't understand that part. - Rich Beckman Tue, 16 Feb 2010 17:27:22 +0100
