Scientists are pondering an idea of adding lime to seawater to reduce CO2 levels. The open source collaboration model is being used to flesh out the idea. From Physorg (in a slightly different order):“Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. The process of making lime generates CO2, but adding the lime to seawater absorbs almost twice as much CO2. The overall process is therefore ‘carbon negative’. However, the idea, which has been bandied about for years, was thought unworkable because of the expense of obtaining lime from limestone and the amount of CO2 released in the process.”Cquestrate, the group behind the idea, intends to use open source principles to bring the idea to reality. The group is attempting to restrict patents from being secured as a result of the project. Participants are asked to post their ideas and suggestions on the Web site, thereby disclosing the information for everyone to see and build upon.Very cool idea and cool use of openness to benefit humanity.
