Directory of technologies and resources pertaining to wave buoys that convert the ocean or sea wave energy into electricity. The flotation portion undulates with the waves, while a fixed shaft provides the counter-active force from which energy can be generated.
"In the permanent magnet linear generator buoy, an electric coil surrounds a magnetic shaft inside the buoy, and while coil is secured directly to the buoy (see illustration), the magnetic shaft is anchored to the sea floor. When waves cause the coil to move up and down relative to the fixed magnetic shaft, voltage is induced and electricity is generated. Each buoy could potentially produce 250 kilowatts of power, and the technology can be scaled up or down to suit a variety of energy needs. A fleet of about 200 such buoys could power the business district of downtown Portland." (PhysOrg)

Annette von Jouanne list of publications by OSU faculty member key in wave project.
Team led by Annette von Jouanne and Alan Wallace
: "With this type of system, it would be possible to crank the buoy beneath the ocean surface to survive severe storm conditions or tsunamis." (source)
: "Oregon State University's proximity to the Pacific coast combined with strategic research facilities in the OSU Motor Systems Resource Facility and the O.H. Hinsdale Wave Research Laboratory make it a leader in this new technology. The researchers are planning a demonstration facility to test this developing technology in conjunction with the Electric Power Research Institute and others." (PhysOrg)
Directory:Pelamis Wave Power - separate feature page. The Pelamis Wave Energy Converter is a revolutionary concept, the result of many years of engineering development by PWP. It was the world’s first commercial scale machine to generate electricity into the grid from offshore wave energy and the first to be used in commercial wave farm projects. (PESWiki)
Uppsala's unique wave energy ready for commercial deployment - Swedish Uppsala University researchers have developed an entirely unique energy technology that is adapted to the slow movements of waves. It is driven by a linear generator, to which a buoy is attached with a line. Now this technology is to be deployed in the world’s first commercial wave power array.
Directory:Ocean Wave Energy >Directory:WaveReaper - Because of its design, the WaveReaper™ by WavePartner, is always self-adjusting regarding wave height and tidal shifts and higher or lower water levels, due to shifting weather patterns. The Wavereaper™ is always balancing itself out, to optimal level in the ocean.
Wave Dragon - Wave Dragon is a floating, slack-moored energy converter of the overtopping type that can be deployed in a single unit or in arrays of Wave Dragon units up to 200 resulting in a power plant with a capacity comparable to traditional fossil fuel based power plants. YouTube
ABB - The WEC device developed by Fred Olsen Ltd looks like a traditional rig with floating, egg-shaped cylinders hanging underneath it, that absorb energy from the waves as they move up and down. This linear, vertical motion is then converted to rotational motion by means of a hydraulic system – a hydraulic motor drives a generator to produce electricity.
Wave Hub - Renewable energy project in the South West of England that aims to create the UK's first offshore facility for the demonstration and proving of the operation of arrays of wave energy generation devices.
SeaVolt Technologies - Wave Rider consists of a special buoy that bobs up and down with wave action on the ocean surface. A hydraulic circuit captures the slow rolling energy of the wave and converts it into high-pressure hydraulic fluid flow, spinning a turbine to generate electricity.
Ocean Motion International - The OMI WavePump uses a buoyant vessel which rides on the wave surface. The bottom hull is flooded and descends to the ocean floor to become the footing. When a trough passes beneath the buoyant vessel, a heavy ballast mass descends and pressurizes the water in several sleeve type pumps.
Directory:Suppression >Article:WaveReaper and Stefan Nystrom - On Wednesday, an article at Rense.com stating that Stefan Nystrom, who was involved in an ocean wave energy technology that allegedly could have provided electricity cleanly at 5% the cost of fossil-based power, appears to have disappeared suddenly under suspicious circumstances, and may even have been killed. (PESWiki Sept. 5, 2008)
