⑤The constant rocking of the ocean drives hydraulic pumps that push
seawater and other liquids through a pipe to a power plant nearly two
miles away on Garden Island. There, the high-pressure water turns
standard hydroelectric turbines, which power a generator. Wave energy
from the buoys also pumps high-pressure water through the desalination
plant, without using fossil fuels. In contrast, many desalination plants
use diesel fuel or electricity to pump saltwater at high pressure through
membranes to yield fresh water.
