Wave of Energy

PostedApril 1, 2005

About half the U.S. electricity demand is along its coasts.  So engineer Annette von Jouanne, of Oregon State University, says we should be looking for energy in the motion of the ocean.  She thinks newly developing technologies could capture at least as much energy as wind or solar power, using smaller, less expensive engineering from a more consistent and predictable source.  Plus, the devices could be mostly underwater and virtually invisible.  Von Jouanne is experimenting with prototypes in which bobbing water causes coils to move through a magnetic field to create electricity.  Undersea cables could then send it to the power grid and your reading lamp.  With the National Academy of Engineering, Randy Atkins, WTOP Radio.
