Publication of International Patent Application on Elpipes

March 14, 2011: WIPO (World Intellectual Property Organization) will publish Electric Pipeline Corporation’s ground breaking International patent on elpipes, “Underground Modular High-Voltage Direct Current Electric Power Transmission System” on March 14, 2011 [1]. This 130 page, 84-claim PCT patent application covers many different aspects of elpipes, which are polymer-insulated electric pipelines. Some aspects of elpipes include continental-scale supergrids in which elpipes are hybridized with superconducting lines, overhead lines, and other HVDC technologies [2]; resistance of elpipes to sandstorms [3]; or the trade-offs on conductor selection [4] for example have been previously discussed. Additional pending scientific papers discuss additional features and advantages for elpipes which are revealed in this patent application, such as improved insulation [5] and significance of HVDC loops based on elpipes for load leveling [6].
