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 kWh 4,000,000 need to diversify 3,000,000 and use the alternative energy 2,000,000 sources that are 1,000,000 available to us. 0 1999 2000 2001 2002 2003 2004 2005 2006 Years Total kWh Generated Fuel C ost ($) 1 Yakutat Power 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 world. 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 v8.2 SyncWave Power Resonator: Offshore Wave Power for off-grid, load displacement, and utility applications Wave energy • Very large opportunity, multiple addressable segments SyncWave Power Resonator • Up to twice as efficient as the market leader • Key technology IP in configuration and control • Simpler to build & out-source • Self-tuning for efficiency & survivability • Long-life, easier to deploy & service • Strong technical consortium v8.2 Senior Team President & CEO: Nigel Protter, MBA • Experienced Technology Manager • Green Hydro Development & Permitting • Clean Energy Policy Energy Markets: John Gunton, PhD • Chairman, Energy Analyst Finance & Strategy: John Bean, CA • Director, Energy Tech Investor Chief Scientist: Brad Buckham, PhD • Subsea Dynamics & Hydrodynamic modelling, ROPOS Underwater Vehicle Director of Mechanics & Integration: Peter Wild, PhD, P Eng • Former Director IESVic Energy Institute, NSERC Mechanical Design Chair Director of Ocean Engineering: Geoffrey Jackson, MRINA, CEng, Cphys • 30 yrs British Maritime Technologies (BMT) Fluid Mechanics, Sr. Project & Test Engineer v8.2 Technology QuickTime™ an d a H.264 de compressor are need ed to see this p icture . • Slack moored • Self reacting • Counter oscillating • Resonator • Loss-less tuning • Mechatronic control • Relatively simple to build • Industry Leading IP in configuration and control v8.2 Efficiency Progression SyncWave Performance Trend, (using a 20 year straight line amortization of CAPEX, corporate overheads, margins, warranties, burden etc. included in R1 and R2 costs), The charts use outputs from the SyncWave Performance Simulation model, the SyncWave Pro Forma Business Model, and extrapolated wave data from Amphitrite Point, BC v8.2 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 mooring. • 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. v8.2 SyncWave’s Basic Operating Principles Float Float Pillar Position Pillar Position Generator Rotation Generator Water Level • 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 v8.2 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. v8.2 Active Tuning: SyncWave Energy Latching System 8 7 6 Average Power (W) 5 4 SWELS on 3 SWELS on: cG=115 Ns/m 2 SWELS off: c G variable 1 SWELS off P =0.20 0 1.5 2 2.5 3 3.5 4 4.5 (rad/s) v8.2 Alpha Project Location Buoy Location 1 - Axys Environmental Directional Wave Buoy N49 03.398 W126 09.153 Approximately 70m depth v8.2 The Alpha Ocean Going Prototype • The Alpha is a 29 tonne device that is being designed for operation off of the West Coast of Vancouver Island. • Overall diameter is ~2 m. 2000 • Currently restricted to using Wave Band near shore wave data for the 1800 stage 1 tuning procedure. 1600 Hours Feb 2002 - Feb 2004 • Data was collected off of 1400 Amphritite Pt. by BC Hydro 1200 between 2002 and 2004. 1000 • An Axys wave buoy is being deployed off of Lennard 800 Island lightstation this 600 summer to sample a more promising location for the 400 Alpha. 200 0 2 4 6 8 10 12 14 16 Wave Period (s) v8.2 Beta Project Location?…we’re working on it!
