The Current Situation Tidal Energy is sustainable, clean, reliable, widely distributed, and can offer significant benefits to many marine nations. Tidal Energy can be captured in an efficient and cost-effective way. Slide 4: Tidal Energy is a clean, renewable source of energy--such as solar, wind, biofuels, and low-head hydro-- and deserves official international support and funding for its development. Slide 5: The Worldwide Distribution of Tidal Energy Slide 6: World Map of the Distribution of Tidal Energy Red areas show most intense tidal energy Slide 7: Developing Nations that could receive significant benefits from Tidal Energy ________________________________________ Indian Ocean: Comoros, Madagascar, Maldives, Seychelles. Asia: China, India, Indonesia, Korea, Philippines, Vietnam. Pacific Ocean: Fiji, Kiribati, Micronesia, Palau, Papua New Guinea, Samoa, Solomon Islands, Timor, Tuvalu, Vanuatu. Central and South America: Argentina, Brazil, Ecuador, Guyana, Panama, Surinam. Atlantic Ocean: Cape Verde. All coastal nations with tidal passes between coral reefs or offshore islands. Slide 8: Significant benefits from using Tidal Energy include: Electrification of isolated communities Generation for the grid Regrowth of coral reefs using mineral accretion technology Substitution of imported petroleum used to generate electricity Slide 9: Efficient technology to capture Tidal Energyis already cost-effective Slide 10: Prof. Alexander Gorlov of Northeastern University with the helical turbine he invented and perfected Tidal Energy can be captured efficiently and inexpensively using the helical turbine Slide 11: Features of the Helical Turbine: Basic Concept designed for hydroelectric applications in free-flowing water operates in ocean, tidal, and river currents does not require expensive dams that can harm the environment Slide 12: Features of the Helical Turbine 35% Efficiency Slide 13: Features of the Helical Turbine Power increases 8 times when velocity doubles Source: GCK Technology I Knot = 1.69 ft/sec I M/sec = 3.28 ft/sec Features of the Helical Turbine Installation Cost: dollars/kw : Features of the Helical Turbine Installation Cost: dollars/kw Source: GCK Technology, Inc. Red: high estimate Blue: low estimate Slide 15: Multiple Benefits from Tidal Energy Slide 16: Multiple Benefits from Tidal Energy. _______________________________________________________________________________________________________ Practical Examples: Electrification of isolated communities Power for the grid Regrowth of coral reefs using mineral accretion technology Slide 17: 1) Electrification of Isolated Communities: The Tide-Energy project near the mouth of the Amazon Rural residents with a 6-blade helical turbine Slide 18: (a) 6-blade helical turbine (b) Pulley and belt (c) Automotive alternator The Tide-Energy project near the mouth of the Amazon: a simple generating package Slide 19: Accessible: About 90% of a tide-powered station can be built using locally-available labor, materials, and equipment. Only the technically-refined helical turbine blades are outside components. The Tide-Energy project near the mouth of the Amazon: simple, accessible, affordable technology Simple: The helical turbine rotates on a shaft with a pulley that runs an alternator by means of a belt. The alternator charges batteries for household use, as is usual with other intermittent sources— solar and wind—when used off the grid. Slide 20: The Tide-Energy project near the mouth of the Amazon: simple, accessible, affordable technology Affordable. Under local natural and economic conditions: The investment in installation and equipment of a tide-energy station is only 50% of the comparable solar option. That investment is similar to the cost of a small, diesel-powered boat, which thousands of people in the region already own. The operating costs of a tide-energy station are less than 60% of those of the comparable diesel option. Slide 21: 2) Power for the Grid The Uldolmok Strait Pilot Project in Korea 1m x 2.5m GHT from GCK Technology, Inc. Slide 22: 3) Generation of hydrogen for fuel cells from the electrolysis of water from tidal currents that do not need to be in close proximity to end-users. The Gorlov Helical Turbine modules can be assembled in large-scale power farms, as depicted in the artist’s conception above. Detail of the Farm Projected Power Farm 1 2 3 4 Slide 23: 4) Regrowth of Coral Reefs Using Biorock Technology: Karang Lestari coral reef and fisheries restoration project, Indonesia Slide 24: Biorock shore protection project at Ihuru Island, Maldives, turned a severely eroding beach into 15 meters (50 feet) growth in a few years Before: Severe erosion Slide 25: Biorock reef in front of the beach uses electricity to grow solid limestone rock on a steel frame and to grow corals. This slows down waves, causes sand to settle, and attracts fish. Slide 26: Conclusions Tidal Energy is sustainable, clean, and reliable. Tidal Energy is widely distributed and can offer significant benefits to many coastal nations. Tide Energy can be captured in a practical, efficient, cost-effective way. Tidal Energy deserves to be included on the list of sources of sustainable energy supported and funded by CSD, GEF, UNDP, IEA, UNIDO, CDM, etc. You do not have the permission to view this presentation.
