Wave power from the seas, oceans, and even lakes is a significant energy resource that is largely untapped despite the fact that energy density in waves is estimated at over 800 times higher than in the wind, currently the most popular alternative energy resource. Typical ocean waves contain the power equivalence of 15 to 50 homes' electricity requirement per one metre width of wave-front. The global potential of usable wave power is estimated to range from 7% to 70% of the world's total energy consumption. Other factors to consider when talking about electric energy production are the environment and aesthetics. Unlike fossil-based power stations, wave power does not generate any harmful greenhouse gases.

A wave power test plant has been deployed on Nov. 17 two miles offshore of Fort Pierce, Fla., and is now being tested by its designers, researchers from Florida Institute of Technology’s College of Engineering.
The power plant has been named “Wing Waves,” and works by harvesting the elliptical motion of waves 30 to 60 feet deep, and converting it into electricity.

The type of wave turbine which Vattenfall intends installing off Shetland in 2014 has produced electricity for the first time.
The 750 kiloWatt Pelamis P2 machine, named Vagr Atferd, is the first of its type tested anywhere in the world and began generating power on Tuesday last week in Orkney for power company E.ON. It arrived at Orkney’s European Marine Energy Centre (EMEC) in May.
Snapping wave energy system gets funding award

Engineers given £20,000 for novel rotary wave energy generator.
The money has been awarded to the National Renewable Energy Centre (Narec) and will fund a research project by Newcastle University's Resource Centre for Innovation and Design (RCID).
OPT reveals wave energy grid connection success in US
Published by SwellGen on September 28th, 2010
StockMarketWire.com - Ocean Power Technologies says it has
completed the first-ever grid connection of a wave energy device in the
US at the Marine Corps Base Hawaii in conjunction with the US Navy.
This
connection demonstrates the ability of OPT's PowerBuoy systems to
produce utility-grade, renewable energy that can be transmitted to the
grid in a manner fully compliant with national and international
standards.
The PB40 PowerBuoy is part of OPT's ongoing programme
with the US Navy to develop and test the PowerBuoy wave energy
technology.
The project began as a small business innovation research programme at the Office of Naval Research.
SIE-CAT Wave Energy Accumulator

SIE-CAT™ technology provides a two-phase approach to harnessing wave energy. In many ways, it is analogous to and competitive with a land based hydraulic project:
Searaser device promises "lowest-cost" offshore power

By Stephen Harris, 18 June 2010, theengineer.co.uk
A new device for harnessing wave energy is promising renewable electricity at a cost to rival fossil fuel sources.
The inventors of the Searaser, an ocean-based pump that drives an onshore hydro-electric turbine, claim it can generate electricity at a rate of 1.5p per kWh – less than a quarter of the cost of other renewable sources and even lower than coal, gas or nuclear.
