The Prognosis for WWT Technology's role in the future in the Extraction of Renewable Energy from Water Currents.
It is foreseen that WWT Technology will become the major player in Energy Extraction from water Currents because its Technology lends itself to the production and employment of very large WWT’s that will be able to produce many Megawatts of Power per unit.
Water represents the largest single potential as a source of renewable energy, since it comprises over 70 percent of the earth’s surface, and therefore is the biggest receiver and medium to store solar energy that it spreads through currents, and it also manifests its gravitational interplay with the Sun and Moon as usable Tidal Currents.
It is clear that there are many benefits in utilizing freshwater and ocean energy technologies, including:
Technological breakthrough in Renewable Energy Generation from water currents
This resource has four times the energy density of a good wind site, thus the diameter of water turbines can be less than half that of a wind turbine for the same energy output in case of kinetic energy only. Water is approximately 800 times denser than air providing for more ease of operation, thereby reducing the size, costs of manufacture and installation.
The water velocities and therefore power outputs are completely predictable once accurate site measurements have been established. With the above in mind, the WWT was designed to exploit the Potential and Kinetic energy in currents that has been largely untapped up to now, and that includes tidal currents that vary from very shallow to very deep.
Water turbines will not need to be designed for extreme atmospheric fluctuations as required with wind turbines, meaning that the design can be better cost optimized.
WWTurbine will have a lifespan in excess of 40 years.
Eco- and Bio-Friendliness
Energy capture from this source using these open-flow technologies, as the WWTurbine, is the most environmentally benign technology available.
The installation process of these systems are not environmental negative, as compared to the installation impact associated with hydro-electric dams, run-of-river projects and the total visual impact of wind turbines.
Technologies that extract energy from marine currents without the use of barrages eliminate the consumption of fossil fuels and the generation of pollutant by-products such as green house gasses. (Hydro electric dams do not fall within this category as they produce massive quantities of CO2).
WWTurbine systems can be installed without total disruptions to marine traffic.
The WWT technology is potentially modular and avoids the need for large civil engineering works at the location.
The environmental impact resulting from marine current energy extraction by the WWTurbine is expected to be minimal to zero.
With the increased conflicts and competition over land surface use, Water Wall Turbine offers a solution that will hardly occupy any land, and has minimal visual impact. WWTurbine has an extremely small footprint.
Design Versatility to suit Specific Needs
Progressive installation can be arranged to suit available financing, and existing facilities are easily expanded to increase production as needed. The facilities are scalable in size to meet the requirements of a small to large scale production of electricity into the power grid.
Energy Predictability and Availability
The greatest Current Energy resources are in close proximity to coastlines and many areas with high population densities. Tidal and fresh water current energy is predictable and quantifiable in advance.
Tidal current energy will not be affected by global climate change.
Tidal current energy peaks at different times at different sites allowing a smoothed out power delivery into the electrical grid systems.
Present tidal current energy generation costs show that these costs are much lower than wind, solar, bio-mass and fuel cell systems and are comparable in per kilowatt production costs of electricity from hydro-electric dam projects. The installation costs are however a fraction of that of a Hydro-electrical dam project and it has none of the extremely negative GHG emissions as from such a large dam.
Industry observers feel that hydro-electricity is the only renewable energy source, presently under development, but is poised to eventually be the biggest contributor to, not only renewable energy supply, but as energy supplier as part of the total mix of the world’s energy production.
The long-term freshwater potential exploitation is believed to be 9 to 12 times current hydropower production, (not including marine energy potential).
