"There are a variety of form factors for wave power. Nair describes Oscilla Power’s system, for example, as “the opposite of a boat.” Instead of staying as stable as possible in the water, it moves as much as possible, capturing energy from different types of waves; in stronger waves, it might move front to back or up and down, and for weaker waves, it might move side to side. “The net effect of all of this is it translates to a very high energy capture, which addresses one of the primary weaknesses of wave energy devices,” Nair says. Traditionally, he says, most designs have focused on trying to capture power from one type of wave, meaning that they’re inefficient the rest of the time. Columbia Power, another company that will soon begin tests of one of its devices in Hawaii, has a “wave farm” system of multiple devices that rotate in each passing wave."
