New System to Fight Climate Change Source:  MIT image of the system New Carbon Capture Technology from MIT Engineers This new technology is from MIT engineers to clean the air of CO2 and fight climate change.  Their invention removes CO2 from air streams at almost any concentration levels from the open air to emissions from power plants.  MIT says it works like a large battery and it requires low energy and low money to operate when compared to other approaches. Like a Battery Like a very large battery, the MIT system absorbs CO2 from a gas stream that passes over its electrodes as it charges up.  While going through the process, the device alternates between charging and discharging.  During the charging cycle, fresh air blows through the system.  During discharging, concentrated carbon dioxide blows through.  As the process is done, pure carbon dioxide is discharged.  The MIT engineers say their carbon capture tech shows the power of electrochemical approaches

Mechanical Trees Pull Carbon Dioxide from the Air Source:  Arizona State University New Technology for a Cleaner Environment Researchers at Arizona State University have invented Mechanical Trees, a new technology that pulls carbon dioxide out of the air and captures it for reuse.  Just 12 trees are capable of removing 1 metric ton of CO2 a day for less than $100 a ton.  That's a significant cost advantage and the team says the technology is ready for commercialization.  For more details, go to Important Innovations Collection: Mechanical Trees For Cleaner Environment : New Tech to Cut, Capture & Reuse CO2 Source:  Arizona State University A Start to Reducing Climate Change A team at Arizona Sta...
