@article{(Open Science Index):https://publications.waset.org/pdf/10006851, title = {Low-Cost Space-Based Geoengineering: An Assessment Based on Self-Replicating Manufacturing of in-Situ Resources on the Moon}, author = {Alex Ellery}, country = {}, institution = {}, abstract = {Geoengineering approaches to climate change mitigation are unpopular and regarded with suspicion. Of these, space-based approaches are regarded as unworkable and enormously costly. Here, a space-based approach is presented that is modest in cost, fully controllable and reversible, and acts as a natural spur to the development of solar power satellites over the longer term as a clean source of energy. The low-cost approach exploits self-replication technology which it is proposed may be enabled by 3D printing technology. Self-replication of 3D printing platforms will enable mass production of simple spacecraft units. Key elements being developed are 3D-printable electric motors and 3D-printable vacuum tube-based electronics. The power of such technologies will open up enormous possibilities at low cost including space-based geoengineering. }, journal = {International Journal of Environmental and Ecological Engineering}, volume = {10}, number = {2}, year = {2016}, pages = {278 - 285}, ee = {https://publications.waset.org/pdf/10006851}, url = {https://publications.waset.org/vol/110}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 110, 2016}, }
