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 Cockcroft–Walton (CW) generator, or multiplier, is an electric circuit that generates a high DC voltage from a low-voltage AC. [1] It was named after the British and Irish physicists John Douglas Cockcroft and Ernest Thomas Sinton Walton, who in 1932 used this circuit design to power their particle accelerator, performing the first artificial nuclear disintegration in history.

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. OE Buoys are assembled on land and then transported by boat to optimal energy locations. [11] [12]
Some filters are designed to provide enough feedback to go into self-oscillation, and it can serve as a sine-wave source. ARP Instruments made a multifunction voltage-controlled filter module capable of stable operation at a Q over 100; [ 2 ] it could be shock-excited to ring like a vibraphone bar.
Due to high cost of a generator, a set of sensors and limiters will trigger the alarm when the generator approaches the capability-set boundary and, if no action is taken by the operator, will disconnect the generator from the grid. [3] D-curve expands with cooling. The D-curve for a particular generator can be expanded by improved cooling.
This network is more akin to the power factor correction circuits used in electrical power distribution, hence the association with Boucherot's name. A common circuit form of Zobel networks is in the form of a bridged T network. This term is often used to mean a Zobel network, sometimes incorrectly when the circuit implementation is not a ...

Pelamis Wave Power tested their first full-scale prototype at the Billia Croo wave test site at the European Marine Energy Centre (EMEC) in Orkney, Scotland between 2004 and 2007. The machine, which was rated at 750 kW, was the world's first offshore wave power machine to generate electricity into the grid system.
