Interest in hydrokinetic energy ? which generates power by using submerged or partially submerged turbines that harness the energy from flowing water ? is on the rise throughout the world. Renewable energy advocates, governments and investors are increasingly becoming aware of river currents and the huge associated energy potential. Because hydrokinetic power generation relies simply on the extraction of energy from the natural velocity of water, these power systems can be placed into sources of flowing water with minimal infrastructure or environmental impacts.
Our patented hydrokinetic technology is designed for use in river and ocean currents with horizontal / inclined axis 3D turbines with diagonal jet blades. The core of our patented technology is both the 3D turbines design and jet turbine blades. The 3D turbine with diagonal inclined tapered blades operates very efficient in very broad range of water speeds and starts to rotate by itself at a very low flow speed achieving much better performance. By 3D rotor is harnessing much more flow stream energy in comparison on the well known prop / impeller turbines. In addition we find out that the speed of water passing near turbine blades impacts of the turbine efficiency significantly. That is why our new invented 3D turbines overcome theoretical Betz limit without any ducts arrangements and/or other
diffuser/co-fuser augmentations. Zero environmental impacts.
The turbines are inclined mounted on a catamaran/three-maran type hull or barge and partially submerged into the water flowing beneath the barge.
In an open-river setting, hydrokinetic power projects will have a capacity factor (CF) of better than 98% because power will be generated by using constant water current to the effect that it would be considered a ?base load? plant.
The rotational speed of the turbine is very low, and can be stopped from spinning in a matter of seconds through automated fault sensing equipment and the turbine can be lifted out of the water and placed in service mode in under 5 minutes.
The barge on which the turbines are mounted (and the turbines themselves) is able to cope with fluctuations in water levels, substantial velocity increases, and direct impacts from large and fast-moving debris, (the turbine is self-cleaning for small debris and floating plant material) and the only flow parameter that would decrease power output would be a decrease in the flow rate of the water underneath the barge. During extraordinary adverse conditions or flood events, the barge could be removed from the river if necessary.
Since the power is proportional to the cube of velocity and density of the water, a slower flow rate of (say) 1 meter per second will yield less energy than a flow rate of (say) 2.5 meters per second, and depending on location and other factors such as depth, our turbine blade size would be engineered for optimal performance given specific site conditions. For instance, the turbine blade could be long for slow moving deep currents, or shorter for fast moving shallow currents.
The power barge is designed to last for at least 20 years lifespan, and because of very few moving parts, will have very low maintenance costs and downtime.
