    CETO Project Update – Successful Sea Trials
    �� Outstanding results from initial in-sea CETO II trials
    �� Onshore CETO test rig complete
    �� 1st complete CETO II pump on track for sea deployment within weeks
    Carnegie Corporation (ASX:CNM) is pleased to announce that results of initial in-sea trials
    of its CETO II wave energy technology show near perfect correlation with results predicted
    by CETO computational models, confirming its design and clearing the way for
    deployment of the first commercial CETO II units within weeks.
    The initial deployment will be closely followed by the deployment of subsequent units, and
    it is expected that a small array of CETO II units will be operating off Fremantle by the end
    of 2008 in addition to deeper water CETO III tests. These final aspects of development
    will allow CETO to be commercial-ready in 2009 as previously advised.
    Construction of an onshore test rig has also been completed which allows testing of all
    pump units prior to ocean deployment as well as ongoing accelerated life cycle testing to
    confirm the reliability of the units in parallel with in-sea trials.
    Carnegie Managing Director, Dr Michael Ottaviano, said: “These results are a major
    milestone on the pathway to CETO commercialisation as they confirm the potential of the
    commercial CETO II design and validate all work done to date in the virtual environment.
    “Once we finalise the location of our first commercial-scale demonstration project, we will
    be able to accurately tailor the CETO system to the specifics of that location using the
    validated virtual CETO models, reducing both time and risk,” he said.
    About In-Sea CETO II Trials
    Testing was designed to compare data measured in-sea with data predicted by the
    CETO’s Computational Fluid Dynamic (CFD) modelling system. This system allows an
    infinite number of design parameters to be virtually tested at full-scale in a variety of ocean
    conditions, and is the final step before physical CETO II prototypes are deployed in the
    ocean.
    CETO pump components were deployed with instrumentation attached in order to
    measure the real forces attracted by the Buoyant Actuators in varying wave conditions,
    with the measured data relayed back to onshore computers.
    The real measured data has now been compared to the data predicted by the CETO CFD
    models and shows excellent correlation. An example of the actual measured results as
    compared with those predicted by the virtual models is shown below. The bold green and
    black data sets are actual measured data and the thin grey lines, the predicted data.
    Background to CETO Development
    Following the successful proof of concept milestones of CETO I at Fremantle, Western
    Australia in 2005 and the production of power and water in 2006, much of the commercial
    CETO II design development has been carried out utilizing complex Computational Fluid
    Dynamic (CFD) modelling.
    These models involved the development of a purpose-built virtual ocean that requires
    sophisticated hardware and software. It allows an infinite number of design parameters to
    be comprehensively tested at full-scale in a virtual environment and in a variety of ocean
    conditions. Such virtual tests preceded the deployment of real physical CETO II
    prototypes in the ocean for in-sea trials.
    For example, design variables such as the size, shape and buoyancy of the buoyant
    actuator along with material selection, pump dimensions and the like have been tested in
    differing wave height, sea and current combinations in this virtual ocean.

    About the CETO Technology
    Named after the Greek ocean goddess, the CETO system distinguishes itself from other wave
    energy devices by operating out of sight and being anchored to the ocean floor. An array of
    submerged buoys is tethered to seabed pump units. The buoys move in harmony with the motion
    of the passing waves, driving the pumps which in turn pressurize seawater that is delivered ashore
    via a pipeline. The high-pressure seawater can then be used to supply a reverse osmosis
    desalination plant, replacing greenhouse gas emitting pumps usually required for such plants. The
    high-pressure seawater can also be used to drive hydro turbines, generating zero-emission
    electricity.
    Other wave energy & CETO characteristics include:
    • Wave energy is a renewable, zero-emission source of power
    • 60% of the world lives within 60km of a coast, minimizing transmission issues
    • As water is about 800 times denser than air, the energy density of waves exceeds that of wind
    many times over, dramatically increasing the amount of energy available for harvesting
    • Waves are predictable days in advance, making it easy to match supply and demand
    • CETO sits underwater, moored to the sea floor, meaning there is no visual impact
    • CETO units operate in deep water, away from breaking waves. The waves regenerate once they
    pass the CETO units, meaning there is no impact on popular surfing sites
    • CETO units are designed to operate in harmony with the waves rather than attempting to resist
    them. This means there is no need for massive steel and concrete structures to be built
    • CETO is the only wave energy technology that produces fresh water directly from seawater by
    magnifying the pressure variations in ocean waves
    • Any combination of power and water can be achieved from 100% power to 100% water
    • CETO contains no oils, lubricants or offshore electrical components. CETO is built from
    components with a known subsea life of over 30 years.
    • CETO units act like artificial reefs in the way they attract marine life.
