									Yakutat Power

       The Reality is we are producing less power
          while the fuel costs continue to rise.
                                                              Less Energy but More $

      If this trend              9,000,000

       continues we will          8,000,000
       not be able to             7,000,000
       sustain reliable           6,000,000
       power in many              5,000,000
       small villages. We

       need to diversify
       and use the
       alternative energy

       sources that are           1,000,000

       available to us.                   0

                       What we now face for
                      power costs in Yakutat.
      At this time we are paying about $.40/kWh of that almost $.20
       is for the cost of fuel alone. While this is not the highest cost in
       the state it is still a fairly high rate.
      I know that we can do better, with all of the talent and natural
       resources available to us we should be the research and
       development leader of most alternative energy sources for the
      Alaska has a rich history of being pioneers and solving difficult
       problems. Alternative energy production should be no different.
       We have many stand alone systems that could each develop
       and perfect many different types of energy resources.
      It may be wind, hydro, bio fuel, geothermal, or a host many
       other resources. I believe that in Yakutat we can harness some
       of the power of the Ocean to help generate power.                    2
Yakutat Power

          Harnessing the Power of Ocean Waves?

      The challenge is to get the process started and
       proven as quickly and effectively as possible. We do
       understand that this will take several years and a lot
       of work so we are going to get started now.
      We would also like everyone else get started now.
       Find out what your resources are, if your community
       has wind use it, if you have hydro use it, if you have
       waves let’s take a look at them and produce power
       with that resource.
      What ever it may be, start developing an alternative
       energy source. It becomes a lot more feasible when
       the cost of fuel is so high.                           3

SyncWave Technology Description

 The SyncWave Power Resonator (SPR)
 is a free-floating Wave Energy
 Converter (WEC).
   •   A reactionless device that is
       deployed with a single point slack
   •   The SPR uses a mechanical tuning
       system called SWELS to optimise
       output for wave climate.
   •   Current incarnation of the SPR is
       Charlotte, a test tank prototype.

SyncWave’s Basic Operating Principles

                                             Float            Pillar Position



                                                      Generator        Water

 •   SyncWave relies on a two-stage tuning process to ensure out-of-unison
     motion of the float and pillar.
 •   The out-of-unison motion causes rotation of the generator.
 •   The motion is driven by the powerful wave excitation force that acts on
     both the float and the pillar

A Priori Tuning: Sizing the Float and Pillar

                             The float is a relatively wide cylinder.
                                •   Large diameter leads to a high
                                    buoyant stiffness.
                                •   High natural frequency.
                             The pillar is a relatively slender cylinder.
                                •   Smaller diameter leads to a lower
                                    buoyant stiffness.
                                •   Low natural frequency.
                             Unlike other technology, SyncWave
                             uses two bodies with significant draft.
                             The greater the draft, the greater the
                             tendency for resonance near the body’s
                             natural frequency.
