• • • Wave power is the capture of energy of to do useful – for example,,, or water. A machine that exploits wave is a wave energy converter (WEC). Wave power is distinct from, which captures the energy of the current caused by the gravitational pull of the Sun and Moon. Waves and tides are also distinct from which are caused by other forces including,, the,, and differences in and. Wave-power generation is not a widely-employed commercial technology, although there have been attempts to use it since at least 1890.

In 2008, the first experimental was opened in Portugal at the. Generic wave energy concepts: 1. Point absorber, 2.

Sin Graph. Attenuator, 3. Oscillating wave surge converter, 4. Oscillating water column, 5.

Overtopping device, 6. Submerged pressure differential Point absorber buoy [ ] This device floats on the surface of the, held in place by cables connected to the seabed. Buoys use the rise and fall of swells to generate in various ways including directly via, or via generators driven by mechanical linear-to-rotary converters or hydraulic pumps. Generated by electrical transmission cables and acoustics of these devices may be a concern for marine organisms. The presence of the buoys may affect fish, marine mammals, and birds as potential minor collision risk and roosting sites. Potential also exists for entanglement in mooring lines.

The wave energy is having more and more interest and support as a promising renewable resource to replace part of the energy supply, although it is still immature. Wave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. It has dimensions of reciprocal length, so its SI unit is the reciprocal of meters (m−1). In spectroscopy it is usual to give wavenumbers in cgs unit (i.e., reciprocal centimeters; cm−1); in this context, the wavenumber was formerly called the Kayser, after Heinrich Kayser (some older scientific papers used this unit, abbreviated as.
