Elizabeth Rusch takes us to Oregon’s wave-battered coast to check out the newest technological research in renewable energy. In this book we find surfer scientists and engineers working to transform the energy in ocean waves into electricity. We meet the Mikes and Annette von Jouanne, the AquaBuOY, and a team of Columbia Power engineers.
The pages are jam-packed with photos of waves, boats, surfers, bigger waves, and turbines of all types and sizes – including the Mikes’ prototype turbine constructed of plastic spoons from a fast-food joint. There are diagrams and graphs that help explain wave motion and watts, and plenty of sidebars that delve more deeply into the issues surrounding wave energy technology.
One question is what happens to sea life when you harness waves for energy. Rusch notes that because the technology is so new, “no one really knows how it will affect marine animals or the environment.” Buoys and other machinery could introduce new sounds and electromagnetic fields into the sea and set cables to thrumming, like guitar strings. Devices that capture wave energy will remove that energy from the waves, and reduced wave power could affect sand movements, water temperature, and water mixing near the shore. Scientists don’t think they’ll increase beach eroion, but they might affect the lives of tiny creatures. If you are interested in learning more about potential environmental impacts, check out the Bureau of Ocean Energy Management and the US Department of Energy Report to Congress (downloadable pdf).
Rusch does a good job of taking us behind the scenes in a growing energy technology field. Some countries are beginning to use wave energy – in small experimental situations. So if you’ve got kids who are interested in renewable energy, waves are the next big thing to watch. And that calls for a field trip to the ocean, right?
