In physics, a wave is an oscillation accompanied by a transfer of energy that travels through space or mass. Frequency refers to the addition of time. Wave motion transfers energy from one point to another, which displace particles of the transmission medium—that is, with little or no associated mass transport. Waves consist, instead, of oscillations or vibrations (of a physical quantity), around almost fixed locations.
There are two main types of waves. Mechanical waves propagate through a medium, and the substance of this medium is deformed. The deformation reverses itself owing to restoring forces resulting from its deformation. For example, sound waves propagate via air molecules colliding with their neighbors. When air molecules collide, they also bounce away from each other (a restoring force). This keeps the molecules from continuing to travel in the direction of the wave.
The second main type of wave, electromagnetic waves, do not require a medium. Instead, they consist of periodic oscillations of electrical and magnetic fields originally generated by charged particles, and can therefore travel through a vacuum. These types of waves vary in wavelength, and include radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
'Wave power is the transport of energy by ocean surface waves, and the capture of that energy to do useful work – for example, electricity generation, water desalination, or the pumping of water (into reservoirs). A machine able to exploit wave power is generally known as a wave energy converter (WEC).
Wave power is distinct from the diurnal flux of tidal power and the steady gyre of ocean currents. Wave-power generation is not currently a widely employed commercial technology, although there have been attempts to use it since at least 1890. In 2008, the first experimental wave farm was opened in Portugal, at the Aguçadoura Wave Park.
Waves are generated by wind passing over the surface of the sea. As long as the waves propagate slower than the wind speed just above the waves, there is an energy transfer from the wind to the waves. Both air pressure differences between the upwind and the lee side of a wave crest, as well as friction on the water surface by the wind, making the water to go into the shear stress causes the growth of the waves.

Blue Energy -- Ocean Power (Piston Pump & Racks) Fluid Pumping Apparatuses Powered By Waves Or Flowing Currents A new invention using "Double acting fluid piston pumps extracting energy from waves or flowing currents into electricity. A revolutionary fluid currents energy converter device by combining double acting fluid pumping apparatuses and moveable racks to convert Ocean waves or flowing currents into electricity. The present invention provide double acting pump mechanisms when the piston reciprocates inside the piston chamber as the piston is driven by a float according to rising and falling waves. Each pumping apparatus is driven by a float; the pumped fluid (water and/or air) is supplied to drive a fluid motor or a turbine, which in turn operates a generator to produce electric...

Exciting new British invention Wave energy converter providing clean renewable energy on demand Find out more at: http://dartmouthwaveenergy.com This ingenious device can pump water upwards using the free and abundant energy in the waves. Once the water is stored at a useful height, it can be released back down driving a turbine and producing an abundance of clean renewable energy. Using pumped water storage is a great way to store energy cleanly to be accessed on demand. http://en.wikipedia.org/wiki/Pumped-storage_hydroelectricity The Searaser can also be used with offshore wind turbines, pumping water up the column of an offshore wind turbine, allowing it to fall and drive a hydro turbine adding more clean renewable electricity, ready to be fed to our homes. http://dartmo...
