WOOSH in conjunction with Blak Magik has developed industry leading wind and hydro energy generation technology that will make a significant impact on the clean energy market. Our CEO and co-founder, Aboriginal engineer and inventor Chris Moore, has designed the Contra Rotating Vertical Axis Wind Turbine (CRVAWT) along with the Farste Drive Toroid PCB Radax Electric Motor/Generator.
Our CRVAWT designs address many concerns with wind turbines providing models that require less space, inexpensive to produce, with faster power generation, and deliver more energy output than traditional wind turbines. Combined with our revolutionary Farste Drive electric motor, our CRVAWTs are significantly lighter, cost effective, and very reliable with a long service life.
Research by others has shown a 60% increase using contra rotating blades and they’ve surmised it was due to increased blade efficiency. It appears they’ve misunderstood the relationship and their increases are due to the Kinetic Energy (KE) increase via the mechanical relationship of 2v², with lower output due to mechanical loss. The CR VAWT design has minimal mechanical loss so the output is higher than their 60% reported increase.
CR VAWT KE = (blade Cd * Area/2)(mass of rotor including (blade structure/2)* v² ) + (Cd * Area/2)(mass of stator including (blade structure/2) * v²) = (blade Cd * Area)(mass of rotor including blade structure + mass of stator including blade structure)2v²
Conventional VAWT KE = (blade Cd * Area)(mass of rotor including blade structure * v² )
Our CRVAWT design can also be used for hydro technology using a similar system which then generates power from water flow – making the turbine a Contra Rotating Vertical Axis Hydro Turbine (CRVAHT).
Our CRVAWT design has tremendous benefits over other types of renewable energy technology including HAWTs, solar and hydro. Some of these advantages include:
The configuration of the CRVAWT allows the rotor and stator to rotate in opposite directions, doubling the actual wind speed and energy output without the need for a gearbox. This feature allows the CRVAWT to have a world leading turbine efficiency of 56% (20% more than HAWTs) and generator efficiency of 98%.
Vertical axis wind turbines can pick up wind coming from any direction. Horizontal axis wind turbines need to face the direction of the wind to operate, and rely on a mechanical yaw system to orientate the rotor in order to capture wind.
Due to this difference in operation mechanism, vertical axis wind turbines can be used to generate power even in unstable weather conditions such as turbulent, gusty wind. They function well in cities, mountain and coastal areas.
In a HAWT wind farm, the general rule-of-thumb for spacing is to place the turbines 14 diameters apart extending downwind. This is to avoid disruption of air flow and reduction in wind speed caused by one turbine to another, which aspects the power output of neighbouring units.
Our CR-VAWTs can be grouped closer together in a wind power plant. This is because vertical axis wind turbines function well in turbulent wind, can be spaced 4 to 6 diameters apart, and will capture more energy per square meter of land.
Our CR-VAWTs have a lower starting wind speed compared to HAWTs. The necessary starting wind speed for a typical vertical axis wind turbine is 2 to 3 m/s.
Our CR-VAWTs bring lower levels of environmental harm including for birds and other flying animals, decreasing the chance of animal casualty.
Our CR-VAWTs spin at a slower rate than HAWTs, thus operate with quieter noise emission, reducing disturbance from noise.
Due to their smaller size, vertical axis wind turbines are easier to transport, set up, and maintain. For example, all parts of one 12kW turbine can be delivered in a single truck with a 6-meter-long storage space.
Maintenance workers do not have to climb as high to reach parts of the turbine because the major components, such as the generators, are built closer to the ground. Farste Drives have 9 x better reliability and longevity than a conventional generator. Low stress blades in VAWT configuration ensures increased service life and reliability.
Being safer to wildlife and quieter than HAWTs our turbines can be erected close to dwellings and existing infrastructure, even integrated into lighting poles/towers, telecommunication towers and neighbourhood batteries.
And mounted on skids that can be sited on existing buildings, or where soil conditions won’t allow standard foundations. Solar needs vast amounts of land and HAWTs need to be located away from populated areas.
The Farste Drive has no copper windings as per a traditional electric motor; instead uses multi-layered Printed Circuit Boards (PCBs) that replicate the properties of copper windings.
The 2 stators pictured below produce the same energy, however the PCB stator (right) weighs less, contains significantly less copper, is simpler and cheaper to manufacture, and is 9 times more reliable than the conventional stators (left) used in competitors Wind Turbines.
To greater understand our CRVAWT’s impact on existing renewable energy technology, it is relevant to make a comparison with solar technology, as a widely used solution. In on-roof installations for CRVAWTs v solar (as an example), the benefits are:
The following diagrams show the efficiency of our CRVAWTs v solar where there is significantly greater consistency for production of energy for each day as well as the year, given also our CRVAWTs do not rely on seasonal differences in sunshine exposure.
