- Wave Power: Energy Buoy to Lead to Wavefarm? -
BBC News reports that a pioneering project to harness wave power off the
coast of north Cornwall, England is being monitored by scientists around
the world. A state-of-the-art energy buoy is being launched 12 miles off
St Ives by the Renewable Energy Agency for the South West (Regen SW) on
Friday. The $132,000 buoy will record wave activity and measure wave
power…Alt

- Wave Dragon – A large-scale ocean-energy solution
for bulk electricity generation – see Wave Dragon web site. 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 in groups
resulting in a power plant with a capacity comparable to traditional
fossil based power plants. The first prototype connected to the grid is
currently deployed in Nissum Bredning, Denmark. Long term testing is
carried out to determine system performance; i.e. availability and power
production in different sea states. The energy absorption performance
stated at this website has now been independently verified and focus
will now be on power production optimisation. These tests will lead to a
multi-MW deployment in 2007.
- Cliff-based Wave Power Potential for UK - Wave power
plants built into cliff faces around the UK coast could be a reality
within the next decade thanks to a pioneering wave energy plant being
developed in a cliff on the Faroe Islands. Inverness based Wavegen, the
company behind the world's first grid-connected wave power station on
Islay, have been working in partnership with SEV, the Faroese
electricity company, to develop a wave power station in the Faroe
Islands. Read more from Renewable

- Aaron Goldin, a senior at San Dieguito High School
Academy in Encinitas, California invented the "Gyro-Gen," a
gyroscope that converts ocean wave energy into electricity. The spinning
gyroscope, mounted in a buoy, resists the movement of the waves by
exerting torque on a crank, which turns an electric generator. See more

- Device for the Utilization of Wave Energy - Norwegian
Patent No.: 311317 and PCT/NO01/0011 - Abstract: Device for the
conversion of wave energy into useful energy, which includes a float (1)
placed around a vertical column (2), a coupling (comprising 4, 5, 6, 7
and 8) and energy converters (9, 10, 11). By means of the coupling (4,
5, 6, 7, 8) the float (1) is arranged for both axial movement and
pivotal movement in relation to the vertical column (2). Energy
converters (9, 10) are placed in connection with the coupling’s (4, 5,
6, 7, 8) pivotal movement, and energy converters (11) are placed in
connection with the bearing unit’s (4) axial movement so that the energy
in both the float’s (1) upwards/downwards movement and pivotal movement
about horizontal axes are utilised. The energy in the waves is thus
transformed into useful energy, eg electrical energy. Read more from here

- Navatek creates electricity from waves - Dec 2006 -
Naval architect Navatek Ltd. has developed a way to turn waves into
electricity. The Honolulu-based company has filed for a U.S. patent on a
wave-energy-conversion device. Original news

- Ocean tide and wave energy converter - United States
Patent 4034231 - Abstract A machine for harnessing the motion of ocean
waves in order to convert the motion energy into useful electrical
power; the machine consisting of a large V-shaped frame, submerged near
a beach, having its apex pointed away from the beach, and the frame
supporting a series of water turbines connected to an electric generator
so that incoming waves toward a beach move along the outer side of the
frame while turning the turbine rotors, and outgoing waves moving along
the inner side of the frame so to likewise influence turning the turbine
rotors. Read more about this patent from

- Apparatus for converting ocean wave energy into electric
power - US Patent Issued on March 14, 2006 - Inventor(s) - Jwo-Hwu Yi;
US Patent References - 5552657 - Abstract: An ocean wave energy
conversion apparatus includes a float adapted to ride on the surface of
the ocean in reciprocal vertical motion in response to ocean wave front
action and a lever adapted to ride on the surface of the ocean. The
lever has one end coupled to the float. A fulcrum pivotally supports the
lever. A magnet is coupled to the other end of the lever. Parallel
stator cores having electric coils wound thereon together with the
magnet form a magnetic circuit. Springs are adjacent the magnet and
interconnected to the lever and the magnet. A barrier is disposed
between adjacent stator cores. The upward motion of the float caused by
impact of waves will move the magnet downward by the lever and
compresses the springs. Downward motion of the float will move the
magnet upward by the lever and expand the springs. Repeated movement of
the magnet will induce a voltage in the electric coils. See this Patent Storm page

- Energy from the motion of the ocean - A former surfer
designs a buoy that can convert wave motion into electricity - By Dan
Drollette, FSB Magazine - December, 2006 - A former surfer's recent
invention is a buoy that can convert a wave's up-and-down motion into
electricity, which can be carried ashore by undersea cables and fed into
the national power grid. The buoys get deployed a mile or so offshore,
either individually or linked together in a field of a dozen or more
covering 30 acres of the ocean's surface. Read the full

About Oilgae - Oilgae - Oil & Biodiesel from Algae
has a focus on biodiesel production from algae while also discussing alternative
energy in general. Algae present an exciting possibility as a feedstock for
biodiesel, and when you realise that oil was originally formed from algae
- among others - you think "Hey! Why not oil again from algae!"
To facilitate exploration of oil production from algae as well as exploration
of other alternative energy avenues, Oilgae provides web links, directory,
and related resources for algae-based biofuels / biodiesel along with inputs
on new inventions, discoveries & breakthroughs in other alternative
energy domains such as solar, wind, nuclear, hydro, geothermal, hydrogen
& fuel cells, gravitational, geothemal, human-powered, ocean & wave /
tidal energy.
