Hydrokinetic  Power Plants with Submerged JET Turbines (Free Flow Turbines)

Clean and Continous Renewable Energy - No Dams!

 Hydrokinetic energy holds significant promise as a new, carbon-free energy source. But known inefficient turbine designs are high barrier of their practical  realization.  Our innovative JET turbine design  has resulted in the most efficient and highest power producing hydrokinetic turbine unit in the hydrokinetic industry. The end result is a system with significantly lower capital costs and higher capacity factors than any other river, tidal or ocean energy system.We in the position to deploy our patented JET hydrokinetic technology at a number of projects throughout the world. Our hydrokinetic power projects that generate electricity exclusively from moving water (river currents, tidal currents and ocean currents) without having to first construct dams, impoundments, conduits or other infrastructure. The technology is also deployable downstream from existing hydropower facilities, which allows for new incremental, environmentally-friendly, renewable power generation within the existing project footprint.

The idea Twin Two Stages Hydrokinetic Turbines, attched to two interconected inclined shafts (see the picture), under development since 2001, was a commercial product based on zero head hydro technology. The challenge was to construct radical new 3D Jet turbine with diagonal blades that mounted face-to-face under a pontoon power barge for efficient operation in slow moving water. The interconnection of the turbine shafts is over water. That way prevents any under water oil pollutions. Our patented twin hydrokinetic turbines system has the potential to achieve an overall efficiency of 80 % and more, realised by using well-known laws of physics and hydrodynamics and its versatility of deployment in site-specific situations.

We have developed a method for the design of a low r.p.m water turbine designed for an operating point about 1 m/s free water flow and less. The low flow speed also means that this design process is also suitable for the hydraulic design of stationary river and tidal generators. Several twin turbine prototypes have been manufactured and successfully tested with a hydraulic efficiency from 20 to 80 % in depend on design and flow speed. The

ROTOJET designs solve two  main problems of the conventional propeller (lift and/or drag) turbine rotors by JET peripheral channels (or semi channel) of the blades. The JET channels have two functions:

The first one is to avoid the tip blade energy loses because of tip vortices,

The second function is much more significant. The second function is acceleration of the fluid current in the JET channel (or semi channel) and it?s directing towards the back of the correspondent blade, and thus the flowing current to create JET stream. In the opposite direction of the JET flow appears JET force/torque which considerably supports the rotation.

Because of the JET channels big part of the fluid pressure over the rotor is redirected into JET force and also due to the channels the inductive blade tip losses of energy are vastly decreased.

During last 10 years we are developing a lot of hydro-kinetic power applications. We have tested ducted and non ducted hydro kinetic turbines. The ducted hydro kinetic applications are more heavy and costly. They require more often and expensive maintenance.

The prevailing world wide practice in zero head tidal plants now is to implement simple and low cost duct less Savonius machines. But they show low efficiency. That is why we have focused on number of options to increase the Savonius machines efficiency.

We find that the around rotor water speed and turbulence affect significantly rotor efficiency. We have developed a mats model for it and have developed respective simulator. Based on both the simulator and water test we propose to you number of options as follow:

As the first option is to use duct less turbines to keep bigger the around rotor water speed and to reduce cost and pay-back of a complete hydro kinetic power plant.

As the second option is to use shaft less Savonius turbines to reduce the around rotor and wake turbulence. It is more important for the hydro kinetic farms and pontoon power barges.

As the third option is to reduce periphery turbine energy losses by application of smaller turbine scoops (instead of 180 degree semi cylinder - smaller)

As the next option is to reduce after wake turbulence by two blade open center Savonius turbine design (negative overlap) with 180 degree offset.

The listed above options in interaction with our radical new ROTOJET designs increasing non ducted Savonius turbine efficiency significantly.

The new ROTOJET designs enhance the Savonius rotor cost by several %. That is why it is the best energy and economical feasible solution.

At next videos you can see the difference in water operation between non jets augmented shaft less turbine with modified scoops and the same, but by a ROTOJET machine design.

Each blade forms an accelerating hydro-jet stream. In the opposite direction of the jet stream, a jet force is formed in the periphery of the rotor. The jet force increases the rotational rate of the rotor.

New Invented Water Vortex Promoter
A lot of people believe that we need more very  complicated innovations and more costly development before being able to produce low cost and clean energy. This is not true. The Vortex Power Plant Promoter integrated a turbine in a little river producing electricity on a cheap basis and in a very clean way.

To build a conventional water vortex power plant in a river, the land must have a downward slope (water head) of at least 0.7 meters. In addition have to construct a spatial canal and respective vortex basin with canal water outlet. Our new technology is based on artificial water head by creating down going force caused by pressure difference between upper and bottom chamber of the new invented Water Vortex Promoter. It is a relative simple low cost facility fixed direct in river bed with low moving water, or on a floating structure (e.g. pontoon).

 

With new technology we can produce much cleaner energy and be much more sustainable.

 

3D rotor of an Axial Flow Hydro (Wind) Kinetic Turbine  for Low Water Speed Applications

We have developed  a method for the design of a low r.p.m water turbine designed for an operating point about 1 m/s free water flow and less. The low flow speed also means that this design process is also suitable for the hydraulic design of stationary river and tidal generators. Several turbine prototypes  have been manufactured and successfully tested with a hydraulic efficiency from 20 to 80 % in depend on design and flow speed. We have demonstrated that the power that can be extracted by a free flow 3D rotor of an Axial Flow Wind Hydro Kinetic Turbine is higher than the "Betz limit" which restricts the total extractable power for an unconfined turbine such as a 2D rotor of a wind turbine. The Betz analysis is widely applied to the free flow water streams, but it underestimates the power because 3D rotor extracts much more power from free flow in comparison with well known 2D rotors.

Localized interactions between devices are of great importance in determining the collective energy yield of a system of turbines (hydro-kinetic parks), as wake effects can significantly reduce total energy yield. We are developing vortex wake modeling techniques to simulate and investigate turbine interaction effects. The results show that the turbine efficiency is affecting on both speeds crossing turbine flow speed and around turbine flow water speed.

3D rotor is a unique device for exploitation of wind / river / canal / tidal current resources. We have completed a very successful set of model-scale tests in and these tests have proven the hydrodynamic – aero dynamic efficiency of the turbine.

Tornado wind turbine (HAWT) with 3D rotor

New Designed 3D  horizontal axis wind turbine (HAWT) for Ultra Low Cut-in Wind Speed. You see on the display of wind speed meter (anemometer)that the wind speed as low as 0.7 m/s when turbine generates voltage - see the multimeter. We often see people post questions on forums, where they are looking for a wind turbine "with a low cut-in wind speed". Typically the cut-in wind speed is the wind speed where the turbine starts turning. For most wind turbines it is around 2.5 - 3.5 m/s (5.5 - 8 mph), New designed 3D rotor of shown HAWT starts rotation at 0.5 m/s. It a Down wind turbine which is much more robust in the comparison of the most popular up-wind turbines.

Up-Front Hub Wind Speed Distributor of Horizontal Axis Wind Turbine

Up-Front open center Hub Wind Speed Distributor of Horizontal Axis Wind Turbine increases low wind Speed that increases rotational speed and efficiency of the turbine generator at low and turbulent wind. The general availability and reliability of wind speed data is extremely poor in many parts of the world. Large area of the world have wind speed in intermediate range (3 to 4.5 m/s) where wind power may or may not be an alternative
option. It is necessary to concentrate on the design and development of Low RPM, High Torque Small wind generator which starts operating at much lower values of Cut-in wind speed and continues to operate through a substantial portion of the year. This will also be of great importance for those areas of the world where annual mean wind speed is low (less than 3 m/s)

New Invented Vortex Power Plant

The patented prototype (not to scale) of Energized Vortex Basin  (EVB) is a facility designed to accelerate natural water vortex by flowing water as slow as 1m/s which is much less than that required for turbines and water mills. The new invented hydro kinetic system has other advantages as it does not require water head, waves or tides. The income water flow passing trough inlet  apertures and energized natural vortex of EVB. At the bottom part of the EVB creates low water pressure by increasing of water speed passing outlet apertures in accordance to Bernoulli principle (e.g. by Coanda Effect). This way an artificial water head is creating to continuously support the vortex in  EVB. The vortex kinetic energy is harnessing by a vertical JET turbine in the vortex center, blade less Tesla turbine or many other rotating machines. EVB is a basic facility of vortex power plant that operates in slow moving water. 

The EVB turbines produce up to several times more energy than tidal turbines with same volume of moving water. The high EVB turbine productivity is based on both natural water vortex circulation and increasing of kinetic water vortex energy by natural implosion.

Paddle Propulsion JET Wheels of a river boat operating as a anchored hydro kinetic power barge

See a video at : www.youtube.com/watch?v=i6r3G2wDFoo&feature=channel_video_title

Electric paddle JET propulsion wheel boats do not require messy fuel or complicated maintenance.
Thanks to the new ROTOJET design of each paddle blade a jet stream is formed behind the blade and a jet rotational force increase paddle efficiency by rotation as boat propulsion device. Our Electric paddle boats already have the motor/generator built-in wheel hubs.
Since electric paddle boats are battery powered they are non-polluting and quiet. Solar PV modules on the boat roof are required for on boat battery charging. A paddle wheels power barge with battery and super capacitors is a part of a smart power grid as well.

The advantages of an electric powered boat are many. An electric boat is quiet, environmentally sound, it encourages conversation and provides a smooth relaxing environment. In most cases the slap of the water against the hull is the prevalent sound. The absence of other appreciable sound is surprising to most people. Sailors especially appreciate the quiet motion of the electric motor propelled boat. Electric boats are also less expensive to operate and maintain in many cases.

As gas and diesel prices continue to rise and there is a greater appreciation for green living, I see exciting times ahead for electric boating.

The rental and ride opportunities have increased dramatically as has the range of boats available on the market. The market choices were once confined to essentially an expensive launch or or small fishing boat with a trolling motor. The choices now include many lower cost options, a great choice of hull type and some very large boats as well. Several large sailing catamarans are now available with auxiliary electric drive including hybrid drives. Large catamarans are especially good regeneration candidates due to their higher speed potential. There has been a rapid rise in the number of solar assisted electric boats available as stock models and as one off boats (mostly in Europe and Australia). This site will introduce you to some of the many types of electric boats now available for purchase, rental and boat rides.

Behind all of this market activity has been a great deal of technological change. Larger permanent magnet brushless motors and their sophisticated controllers have entered the electric boat market and have already boosted e boat performance dramatically in terms of efficiency, simplicity (generally direct drive) and the ability to regenerate electicity (a decided advantage where an electric motor provides auxiliary power for a large sailboat). Some high tech battery types are getting close to the point of making economic sense. Nickle metal hydride batteries have already been used in some marine applications. The AGM (absorbed glass mat) type of lead acid battery is becomming very popular with electric boaters. Fully engineered hybrid systems are now available for small boats and this area is expected to expand. Solar power has proven itself as a charging source and range extender in many commercial and private boats.

Owing to the mentioned above, the JET rotors (propeller or non-propeller) of both hydrokinetic turbines and boat proposition systems are about two and more times more efficient in comparison to the conventional rotors. Such JET turbines are described in the patent descriptions BG110 251/2008 and BG 110 340/2009

ROTOJET turbine designs generally increase both TSR and self starting ability that is very important in tidal operation. But TSR is non linear depending on the water/air speed. The speed of the wind, tidal stream is varying in very broad range. To find the best design of the Jet turbine in tidal stream have to now range of water speed changing, water density and water temperature changing. But much more important is the frequency distribution of the water/wind speed per day / year.

We have demonstrated that the power that can be extracted by a free flow Jet / Lift / Drag ROTOJET Hydro-Kinetic Turbine is significantly higher than the "Betz limit" which restricts the total extractable power for an unconfined turbine such as a wind turbine. The Betz analysis is widely applied to the free flow water streams, but it underestimates the turbine power output. The  Betz  limit not related to the JET assisted wind / hydrokinetic  turbines.

Above description relates single turbine only. The calculations of group of ROTOJET turbine (hydro-kinetic / wind farm) are more complicated.

First ever ROTOJET. Jet / Lift / Drag turbine is the most economical feasible solution of dam less hydropower. And for wind applications as well. The ROTOJET design is very low cost in both manufacturing and operation. See below a basic comparison of different types of wind/hydrokinetic turbines:

Wind/Hydro-kinetic power plant with JET blades on vertical shafts (cross flow turbines)based on a floating anchored pontoon structure. Patented JET turbines formed by hollow blades with elliptic-like cross-section. The blades with side inlet aperture and outlet nozzles at blade trailing edge. It is a radical new patented blade design (ROTOJET) that increases flow-to-power efficiency significantly and helps to increase turbine performance at low and moderate flow speeds and in turbulent flow as well. Easy starting turbines. Patent pending. Integrated oil less power train with a common electric alternator.

Hydrokinetic power refers to the generation of electricity from moving water without impoundments or diversionary structures that are typically used at conventional hydropower facilities. New invented technology operates in open rivers, channels, tidal areas and oceans. It is a new high efficient standard of conversions of water kinetic energy to usable power thank to number of patented radical new technical solutions based on JET augmented turbine rotors. The invented JET hydrokinetic power plants designs include both horizontal and vertical JET turbines. It is basically surface-suspended systems, is also deployable downstream from existing hydropower facilities, which allows for new, environmentally- friendly power generation within the existing project footprint.

As far as the hydro-kinetic turbines have full continuity with the wind turbines then they have also their advantages and disadvantages.
I will not make a list of priorities and shortcomings but will only point the principal disadvantage in applying of the identical approaches to the wind turbines and airplane propellers and respectively to the hydro-kinetic turbines and water propellers:

The principal difference between the fluid propeller motors and the fluid propeller turbines is in their function. The propeller motors have the task to create traction. Their rotation is what creates their traction and it is not an aim but a mean. And as far as there are losses of energy during the rotation then they are parasitic according to the main function – the traction. In each case the losses from rotation are unavoidable.

The mission of propeller turbines in the mass case is to rotate for turning the electro-generator. It means that the rotation is the aim and not the mean as it is at the propeller engines. During their rotation the turbines are subjected to the dynamic thrust of the flow which is unfavorable from energetic point of view. This axial thrust is in a sense analogical to the traction at the propeller motors. But for the turbines it is parasitic from energetic point of view and from mechanical-constructive standpoint it destroys them and is also undesired.

The working Principe of the JET fluid turbines is radically new. The JET propeller turbines rotate by analogical reason causing the rotation of the non-reactive propeller turbines. The propellers of JET turbines rotate by reason of the difference of the flow pressure before and after their blades. But this difference around the outlines and especially at the periphery of their blades is almost zero, because the fluid with enhanced pressure freely passes to the back side of the blade, where the pressure is lower which ultimately leads to losses of energy. This is the first main disadvantage of the propeller turbines. The second one is that the axial stress of the fluid over their rotors is parasitic and does not contribute to their rotation but only loads them mechanically.

The barge is a module of hydro kinetic power farm includes number of interconnected modules with semi submersed axis flow JET turbines. The cost of power generated is about USD 0.04/kWh. The JET turbines are world novelty that increase water-to-power efficiency significantly. The JET turbine is a radical new solution based on low cost well known technology. It is fixed blade variable rpm turbine rotating permanent magnet alternator. see a video at  www.youtube.com/watch#!v=47yepY4Mwzw&feature=channel

The JET turbines solve the main two problems of the conventional propeller turbine rotors by JET peripheral channels of the blades. These channels have two functions:

• The fist one is to obstruct the passing of the fluid with enhanced water pressure to the back side of the blade, where the pressure is lower.

• The second function is acceleration of the fluid current in the tip channel/s to create JET stream. In the opposite direction of the jet  flow appears JET force/torque which considerably supports the rotation. Because of the JET channels big part of the fluid pressure over the rotor is redirected into JET torque and also due to the channels the inductive blade tip losses  are vastly decreased.

Thanks to the additional JET mode of blade rotations new designed turbines can increase the turbine efficiency many times. See  comparisons in operation of JET turbine vs. conventional turbine at: http://www.youtube.com/watch?v=ghp-7MqUyhs  and  http://www.youtube.com/watch?v=bWoLchq3EME ). Such JET turbines are presented in the patent descriptions BG110 251/2008 BG, 110 340/2009 and 110 525/2009.

100 kW Class of Axial JET Hydrokinetic Turbines

We have developed two basic project of the Axial JET Hydrokinetic Turbines:

• First type is applicable in relative low water speed currents or for bottom fixed stream energy converter units. It is a basically non-ducted JET-drag axial flow  turbine with fixed blades variable speed operated.

• The second type is applicable in medium to high water speed currents for pontoon supported structure. It is a non-ducted fixed blades  turbine with JET-lift blades variable speed operated.

Both developed (patent pending) tidal turbines JET/Drag and JET/Lift are relatively low cost solutions  operating with high capacity factor and generating low cost power.

Every axial rotating machine (e.g. turbine) in water creates vortex that forces water tangentially. Tip blade JET channel/s redirect/s the forced water to tip JET stream/s. As a result of the JET stream/s in opposite direction is creating tip JET force/torque.

Free river stream turbine is several meters in diameter. It is possible to develop more than 100 kW  power system by 2x100 side-by-side axial turbines operating in counter rotating mode using a common gearing and electric alternator, power electronics etc..

The non-ducted hydrokinetic power generation relies simply on the extraction of energy from the natural river velocity of water, these power systems can be placed  with minimal infrastructure or environmental impacts.

The JET rotors on the above described turbines turn slowly. A ship's propellers, by comparison, typically run 5 times as fast. The risk of impact from JET rotor blades is small, because the marine creatures that swim in strong currents tend to be agile, and can avoid slow-moving underwater obstructions..

Applications of  JET Turbines Technology

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.

Hydrokinetic energy is not a new application of the concept of using the energy from moving water to create electricity - “dam-less” as opposed to conventional dam wall hydro power or other man-made barricading structures behind which potential energy in the water is stored – water wheels of various types have been used in numerous applications for centuries.

The ideal location for a hydrokinetic turbine is to be located in deep strong flowing rivers or immediately downstream from an existing conventional hydropower plant where electric transmission wires and interconnection facilities are located, and where the energy remaining in the water current exiting from the turbines in the dam can be reused. Small Power Barges in a range of 5 to 30 KW could easily be floated in channeled and engineered waterways such as irrigation canals.

Hydrokinetic technology is designed for use in river and ocean currents with a horizontal axis turbine. Almost like mounting several Pelton wheels on the same shaft but better, as the advantages of a vertically submerged blade has similar performance characteristics to a horizontally mounted Cross flow turbine. The core of our patented technology is in the design of the turbine blades. The leading edge offers reduced resistance, while the trailing edge is aerodynamically optimised to reduce the Flat Dynamic Effect. The turbine is horizontally mounted on a catamaran 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 a 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 2 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) 3 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 and broad for slow moving deep currents, or shorter and thinner 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.
