SEADOG Learns Trick, Pumps Water

Science & Technology (alternative energy)

wavepump.jpgWe have shown a few bouncing buoys before, but here is one with a difference: it pumps water. The water can be stored in a reservoir or water tower for storage, so that consistent power can be delivered when required rather that when surf's up. Minnesota's (famous for its ocean frontage) Independent Natural Resources Inc. (INRI) suggests that a square mile field of SEADOG wave pumps could generate up to 1,500 megawatts of power.

It works, too: "Our sea trial in the Gulf of Mexico has exceeded our expectations and we're confident our engineers have developed a new proprietary technology that serves as a safe, efficient system for gathering renew able energy from ocean waves," said Mark A. Thomas, chief executive officer, INRI. The unit consistently pumped between 15,000 and 40,000 gallons per day. ::Renewable Energy Access
