Salter's duck, also known as the nodding duck or by its official name the Edinburgh duck, is a device that converts wave power into electricity. The wave impact induces rotation of gyroscopes located inside a pear-shaped "duck", and an electrical generator converts this rotation into electricity with an overall efficiency of up to 90%.
The following page lists most power stations that run on wave power, however there are not many operational at present as wave energy is still a nascent technology. A longer list of proposed and prototype wave power devices is given on List of wave power projects .
Wave power, a machine that uses the motion of ocean waves to generate electricity; Wave pool, a machine that generates waves in a pool to simulate the ocean; Shive wave machine, a wave generator that illustrates wave motion using steel rods and a thin wire; Column wave, a theatrical device used to simulate the look of the ocean on stage
The OE Buoy is designed to be anchored far off shore in deep water where storms generate wave activity. It is powered by a Wells turbine and based on a 3-month test, full scale OE Buoys are expected to output approximately 500MW.
A completely different approach to function generation is to use software instructions to generate a waveform, with provision for output. For example, a general-purpose digital computer can be used to generate the waveform; if frequency range and amplitude are acceptable, the sound card fitted to most computers can be used to output the generated wave.
The system will be matched to the turbine based on the available wave resource. The rated capacity of the generator will vary to best match the environmental conditions at the installed location. [2] The firm was developing deep-water technology to generate electricity from easy-to-predict long-wavelength ocean swell oscillations.
