DELBUOY
The design of DELBUOY was developed at the University of Delaware and ISTI Delaware, Inc., with funding from the National Sea Grant College Program, and at the Department of Marine Sciences at University of Puerto Rico with funding from USAID. When the waves lift and then lower the buoy, a piston connected to the bottom of the buoy drives a pump at the ocean floor. The pressure created by the piston is strong enough to drive the sea water through a reverse osmosis filter, removing salt and impurities from the water. Commercialization efforts of DELBUOY stopped after the loss of critical equipment and infrastructure when Hurricane Hugo (1989) devastated the Puerto Rico where the device was being tested.
