Passengers on the Tokaido Shinkansen, hurtling between Nagoya and Kyoto at 285 kilometers per hour, would catch it for only a few seconds: a vast silver crescent hovering above the flat farmland of Gifu Prefecture, wider than three football fields laid end to end. The Solar Ark was one of those structures that seemed to belong to a different era entirely, a spacecraft from a future where energy was harvested in cathedrals rather than power plants. For twenty years, its 5,046 solar panels turned sunlight into electricity in the geographical center of Japan.
