"It's a cool building.
Asahaka is the one wondering which is more important: pumping electricity or generating electricity?! Deep sea water itself has value in that it is sterile, so I imagine this is an experiment to try generating electricity at the same time.
As you're driving along happily, an impressive industrial structure suddenly appears.
Kumejima uses deep sea water for sterile oyster farming, and it seems that there are even greater expectations for its use in the future."
