Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC). Waves are generated primarily by wind passing over the sea's surface and also by tidal forces, temperature variations, and other ...
The Neptune Wave Engine has been developed by Neptune Equipment Corp. in Vancouver, Canada since 2010, when they found they were not able to purchase a wave power system for their cottage. [76] Wave energy is captured with multiple float-pistons constrained to move vertically up and down piles, informally called "doughnut on a stick". [77]
The first focused on the transformation of material, including stone, bronze, and iron. The second, often referred to as the Industrial Revolution and Second Industrial Revolution, was dedicated to the transformation of energy, including water, steam, electric, and combustion power.
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.
In the first test period all electrical power was converted to heat over a three phase delta-connected resistive load. To investigate the impact of a non-linear load on the WEC system, the generator was, during the second test period, connected to a non-linear load consisting of a diode rectifier, capacitors and resistors. The control, load and ...
The PTO system is the second main component of an OWC device. It converts the pneumatic power into a desired energy source (i.e. sound or electricity). The PTO system design is very important to the efficiency of the oscillating water column. It must be able to convert airflow going both out of and into the collecting chamber into energy.

The wave equation is a second-order linear partial differential equation for the description of waves or standing wave fields such as mechanical waves (e.g. water waves, sound waves and seismic waves) or electromagnetic waves (including light waves). It arises in fields like acoustics, electromagnetism, and fluid dynamics.
