The Next Wave: The Quest to Harness the Power of the Oceans
(Scientists in the Field)

Scientists and engineers from around the world work to harness the power of ocean waves, testing their ideas in an Oregon research lab and the stormy seas off the Oregon coast.

Here’s another well-written science title from an author whose previous contributions to the Scientists in the Field series introduced researchers studying volcanic eruptions on Earth and exploring Mars. After explaining the world’s need for renewable energy sources and the force of ocean power, Rusch focuses on three different approaches to harnessing this power that were underway at the time of her writing. She draws in young readers by introducing two engineers as young tinkerers, following their work through college to the development of a company testing an energy-capture device that sits on the ocean floor. An Oregon State University faculty member has equipped a testing ground offshore to monitor different approaches; some of her students are now building a device that uses the up-and-down motion of the waves. A third company has created working wave-powered buoys using a different design. A center spread describes other approaches from around the world. Lively design, clear explanations, text boxes, photographs and diagrams all contribute to an informative look at how people are working right now to find ways to use a previously inaccessible energy source.

Gr 5-8--Rainforests and savannahs, coral reefs and tundra--readers are most likely familiar with these fields in which scientists work. But this time, it is the energy of the physical movement of the global ocean that is the field, and here in this world of watery physics, a series of imaginative, innovative engineers have been designing, building, and experimenting to successfully harness this inexorable surge of energy. Rusch's readable text follows three very varied groups of visionary engineers on this quest: Mike Morrow and Mike Delos-Reyes (who are working on a device that will allow people to sit upon the ocean floor), Annette von Jouanne and her team (working on a floating design), and the cofounders of Ocean Power Technologies, the first to win a permit to generate "ocean electricity" to be marketed to homes and businesses on the Oregon coast. Included are sidebars on a rich variety of topics such as "Working with Watts" and a global inventory of "Wild Wave Inventions of the World." Colorful diagrams and a plethora of photos provide visual stimulation as well. This pellucid look into a promising field of alternative energy (so needed in a warming world) and into the scientists devoting their lives to bring concept into reality is informative, intriguing, and inspiring.--Patricia Manning, formerly at Eastchester Public Library, NY
