Growth in Ocean-Current Power Foreseen

April 1, 2010 — Leave a comment

Flowing at 1,000 times the rate of the Mississippi River, and attaining velocities in excess of four knots, the mighty ocean current system known as the Gulf Stream has mystified and inspired both sailors and scientists for centuries. Now, a group of Florida researchers is seeking to tap the Gulf Stream for power.

Energy use in Florida is anticipated to go up by nearly 30% in the next decade, as more people move to the Sunshine State seeking its temperate climate and sandy beaches. Not surprisingly, the state is heavily reliant on imported energy to meet its growing needs, but researchers at Florida Atlantic University are hoping to change that. The university recently received a research grant of $5 million to examine how the robust ocean currents off of the coasts could be converted into electricity for the state’s consumers.

“This new industry will provide a clean, reliable, and renewable source of energy that can be used to generate electricity, unlimited hydrogen, and potable water, as well as provide alternative methods for residual cooling or A/C [air conditioning],” says Frank Driscoll, one of the project leaders. The university also expects the new industry to bring 26,500 new jobs to the state.

Tidal-current turbines and tidal-stream turbines generate electricity the same way landbased windmills extract power from wind. Tidal current technology has been around-and in use-for years in Scotland and other parts of the United Kingdom.

The Florida wave project is one of the first for the United States. The researchers will work with the U.S. Navy, Department of Energy, the Clipper Windpower Company, and a host of other organizations and institutions in launching the project and the new center.

“This funding will lead to the establishment of a world-class center that will revolutionize future energy production on our planet. We are very excited about developing these innovative, energy-producing technologies,” says Larry Lemanski, vice president for research at Florida Atlantic. -Patrick Tucker
