  • Water > Hydro > Ocean Wave Energy >
    Searaser aquatic power generator takes to the sea - The Searaser system, unlike other wave power technologies, does not generate the electricity in the hostile environment of the ocean but rather pumps saltwater to an onshore generator. "Water and electricity don't mix -- and sea water is particularly corrosive -- so most other devices are very expensive to manufacture and maintain." (Energy Daily; January 23, 2012)


  • Hydro > Wave > Buoys >
    Intentium: Wave Power Development - Intentium AS is a Norwegian based wave power developing company whose concept differs from most other buoy absorbers, with a new focus on the dominant wave direction and wave crest length. The patented concept has a relatively wide float stabilized up against the dominating wave direction, combined with a double acting pump and a buoyancy controlled water anchor. ([Website]; July, 2011)
  • Hydro > Tidal >
    Minesto Kite to Harness Tidal Energy - The underwater kite by Minesto move 10 times faster than the tidal flow at any given time. Speed and energy have a cubic relationship, whereby a kite moving 10 times the speed of the surrounding water yields 1,000 times the energy of the flow on the kites.

Its blades, turning at six to eight revolutions per minute pose no threat to marine life. (BBC; Aug. 12 2010)
  • Water > Hydro > Wave > Buoys >
    Mechanical transfer of wave energy to shore via steel cable - Wave Energy Co proposes a simple and inexpensive method for transferring mechanical wave energy to shore. "Using a simple underwater teeter-totter and a 1/8 inch steel cable coming to shore, we were able to cause a 170 pound weight on shore to bob up and down with each sea wave" with materials cost of less than $2000.

  • Top 100 / Feature: Hydro > Ocean Wave > Buoys >
    Spindrift Hydrokinetic Energy Device - This ocean wave harnessing technology takes advantage of the difference between wave height on the surface versus water stability deeper down. It is a buoy system that locates the alternator in the surface buoy, with a turbine down deep, by which water is accelerated via a venture shape through which the water flows. (PESWiki; Sept. 13, 2010)
  • Biomimicry >
    Design Inspiration from Nature – Biomimicry for a Better Planet - From buildings and bridges to materials and medicine – examining the design of nature has aided in the development of almost every aspect of our lives, and most of us – often without realizing – benefit from these inspired revelations several times a day.

    Huge swell sinks wave energy generator - A 170-tonne wave energy generator which was launched off the New South Wales south coast in March, has sunk in rough seas. Breaking free from its pylons on Friday afternoon it sank on Saturday. Early efforts to tow the barge to safety were abandoned due to rough conditions. Attempts to retrieve the barge will be made this week. (ABC; AU; May 17, 2010) (Thanks Tedd)

    Underwater Ocean kites to harvest tidal energy - A Swedish startup has acquired funding for beginning scale model trials of underwater kites, which would be secured to a turbine to harness tidal energy for power, allegedly at 10 times the speed of the actual tidal current. With a 12-meter wingspan on the kite, the company says one unit could harvest 500 kilowatts while it's operational. (Good; May 13, 2010)

  • Hydro > Ocean Wave > Buoys >
    America’s First Wave Power Farm Coming to Oregon Coast - Each buoy will measure about 150 feet tall by 40 feet wide and weigh in at about 200 tons. A float on each craft rises and falls with the rolling of the waves, driving an attached plunger’s up-and-down movement. A hydraulic pump then converts that movement into a spinning motion, which drives an electric generator. (Inhabitat; Feb. 23, 2010)
