Description

  The present invention relates to a floating structure that travels on an ocean current and a migration system using the floating structure.

  2. Description of the Related Art A technique of constructing an artificial floating structure (artificial island) on the sea and providing the floating structure with a solar power generation facility, a wind power generation facility, and a tidal power generation facility has been conventionally proposed (Patent Document 1). By performing power generation or the like using an artificial island, energy production (power generation) using renewable energy can be performed relatively easily.
