Calcium looping example, adding Ca-looping to all coal-fired plants in the UK would generate enough waste for 33 Mtonnes/yr of cement production, whereas current cement production in the UK is only 12.5 Mtonnes/yr. Hence, if the technology is applied on a large scale, the purge rate of CaO should be optimized to minimize waste. To fully gauge the viability of calcium looping as a capture process, it is necessary to consider the political, environmental, and health effects of the process as well. Though many recent scientific reports (e.g.: the seven-wedge stabilization plan by Pacala and Socolow) convey an urgent need to deploy
A Scientific Support for Darwinism case, as well as announce the results in a press release. The petition was not completed sufficiently early to submit it as part of an "amicus curae" brief for the Dover case. However, if the case was to go to the US Supreme Court, the petition could have been submitted as an "amicus" brief at that time. R. Joe Brandon emphasized that this "Four Day Petition" did not mean that scientific issues are settled by majority vote. What Brandon maintains is that this is an indication of the level of scientific consensus that accepts evolution as a viable established scientific
