Wave master - Stephen Salter, the father of wave power, has seen his technology fall from favour only to come back into fashion. His new device aims to tackle global warming

摘要

WAVE POWER is on the rise. As concerns grow over the need for diverse ways to generate electricity without boosting greenhouse gas emissions, dozens of new devices are taking shape in wave tanks and slipping into the water for testing. But wave power's history dates back more than three decades and, if anyone can claim to be its founding father, it is veteran design engineer Stephen Salter. His Salter's Duck is still the most efficient wave power converter. Now an emeritus professor at Edinburgh University, Salter is still working on ambitious designs for marine power systems - some of which may help reduce global warming in unexpected ways.
