Shimizu Corporation | Shimizu claims: “The energy paradigm shift opens the door to a sustainable society — a shift from economical use of limited resources to the unlimited use of clean energy is the ultimate dream of all mankind. The Luna Ring, our lunar solar power generation concept, translates this dream into reality through ingenious ideas coupled with advanced space technologies. Virtually inexhaustible, nonpolluting solar energy is the ultimate source of green energy that brings prosperity to nature as well as our lives.”

Comment: Space solar power experts I’ve spoken with have advised me that this is not a technically realistic project. More on realistic SSP projects in a forthcoming blog post. – Amara D. Angelica, Editor, KurzweilAI
