The current stage of research for "SPS 2000" pilot plant project requires planing a number of microwave energy receiving antennas, "rectennas", at site within a few hundred kilometers of the equator. For each rectenna this requires selecting a suitable site, deciding its size and specification, estimating the energy storage capacity required, planning the local power distribution network and its operation, and other matters.The final stage of field research involved visites to Colombia in November 1998, Kiribati and Nauru in February 1999, and Gabon in February 2000, Meetings were held in these countries with national and local government officials and/or with interested researchers from universities and research institutes, at which the possibility of their countries participating in the SPS 2000 project was discussed. All were keen to participate, and candidate rectenna sites were identified. In these countries a number of issues were identified.Participants in a meeting at the Insti … More tute for Promotion of Science & Technology (Colciencias) in Bogota, the capital of Colombia, expressed great interest in participating in the SPS 2000 project, and a candidate rectenna site near the town of Pasto in the Andes in southern Colombia was recommended. A site was visited at Tuquerres where Narinho University has an agricultural research center, which could enable research on a high altitude rectenna in collaboration with the National University in Bogota.Kiribati is composed of a number of islands spread across the Pacific ocean, and it was proposed that a first rectenna should be sited in Tarawa, the capital of the country. A rectenna sited over the shallow water enclosed in the central lagoon of Tarawa atoll could be most appropriate. The Solar Energy Company of Kiribati already successfully operates photovoltaic generators for many families in a number of islands, and could play a central role in the planning and management of an SPS 2000 rectenna.In Nauru, the Director of External Affairs showed considerable interest in hosting an SPS 2000 rectenna, provided that help was provided. As an independent nation consisting of a single small island, resources are very limited, but siting of a rectenna could help to develop the interior of the island which is largely unusable due to mining activities in the past.Officials in the Ministry of Higher Education, Research and Technological Innovation in Libreville, the capital of Gabon, stated the wish of the government of Gabon to collaborate in the realisation of the SPS 2000 project. They proposed that a rectenna should be sited in the south-east of the country near the city of Franceville, where the terrain is savanna and easy for siting a rectenna. Staff from the University of Science and Technology of Masuku (USTM) who are already participate in an international Earth observation project would be responsible for collaborating in the planning and operation of the rectenna.

“SPS 2000”试验工厂项目目前的研究阶段需要在赤道几百公里以内的地点规划一些微波能量接收天线，即“整流天线”。对于每一个整流天线，这需要选择一个合适的地点，决定其大小和规格，估计所需的能量存储容量，规划当地的配电网络及其操作，以及其他事项。实地研究的最后阶段包括1998年11月访问哥伦比亚，1999年2月访问基里巴斯和瑙鲁，2000年2月访问加蓬，在这些国家与国家和地方政府官员和/或大学和研究所的有关研究人员举行了会议，讨论了这些国家参加卫生和植物检疫措施2000年项目的可能性。所有人都热衷于参与，并确定了候选的整流天线位置。在这些国家中查明了一些问题。 ...更多信息 哥伦比亚首都波哥大的科学和技术促进委员会（Colciencias）对参加SPS 2000项目表示了极大的兴趣，并推荐了哥伦比亚南部安第斯山脉的帕斯托镇附近的一个候选整流天线场址。参观了位于图克雷斯的纳里尼奥大学农业研究中心，该中心可以与波哥大国立大学合作研究高海拔整流天线。基里巴斯由太平洋上的一些岛屿组成，建议将第一个整流天线安装在该国首都塔拉瓦。位于塔拉瓦环礁中央泻湖浅水区的整流天线可能是最合适的。基里巴斯的太阳能公司已经成功地为若干岛屿的许多家庭提供光生伏打发电机，并可在规划和管理SPS 2000整流天线方面发挥中心作用，在瑙鲁，对外事务主任对主办SPS 2000整流天线表现出极大的兴趣，条件是提供帮助。加蓬是一个由一个小岛组成的独立国家，资源非常有限，但在过去由于采矿活动而基本上无法使用的岛屿内部建设整流天线有助于开发。加蓬首都利伯维尔的高等教育、研究和技术创新部官员说，* 指出加蓬政府希望在实现卫生和植物检疫措施2000年项目方面进行合作。他们建议将整流天线放置在法国东南部靠近弗朗斯维尔市的地方，那里的地形是热带稀树草原，很容易放置整流天线。已经参与国际地球观测项目的马苏库科技大学（USTM）的工作人员将负责在整流天线的规划和操作方面进行合作。少
