Capture, Accelerate, Concentrate
INVELOX technology captures, accelerates and concentrates wind power, to generate electrical power when wind is at its optimum state of energy.
INVELOX replaces conventional wind turbines that incorporate massive turbine generator systems on top of a tower. It is a technology designed to funnel wind energy to ground-based generators. Instead of snatching bits of energy from the wind as it passes through the blades of a rotor, the wind is captured with a funnel and directed through a tapering passageway that naturally accelerates its flow. This stream of kinetic energy then drives a generator that is installed safely and economically at ground level. The wind flow from multiple collection funnels is concentrated in such a way that the resulting power output rises almost exponentially. Bringing the air-flow from the top of the tower to ground level allows the generation of more power with much smaller turbine blades. The tower used is about 50% shorter than traditional wind towers, and uses a ground-based turbine with blades 84% as long.
Key Benefits of INVELOX
Development and planning constraints
The reason wind project developers have expressed a strong interest in INVELOX is simple: the technology not only provides greater power output at reduced cost, it also brings a solution to all the planning and development issues that have undermined the growth of the wind energy industry for the past twenty years.
In the past decade, we have seen residents around wind projects expressing ever increasing concerns over the environmental and health impacts of wind farms on their communities. Project developers face strong public resistance in virtually all proposed wind farms, which causes the dismissal of the great majority of their projects. This situation has not only slowed down the industry, but it has also led to higher development costs. INVELOX wind farms are environmentally friendly, and will not face such resistance.
In addition, INVELOX reduces the footprint of projects considerably, minimizes aviation and military radar interferences, functions at lower cut in wind speeds, can be deployed closer to grid connections, and offers a greater level of reliability and availability than traditional wind farms. As a result, INVELOX wind farms will not only be much easier to implement than traditional wind farms, they will have access to sites where traditional wind farms cannot be installed.
Low Cut-in Wind Speed
INVELOX can generate power at wind speeds as low as 2 mph, whereas traditional wind turbines only start generating at 8.5 mph. INVELOX can therefore be used on very low wind speed sites. Our technology offers a dramatically wider geographical range of use and a higher level of availability.
Reduced Land Use
Thanks to its smaller size and its high performance, an INVELOX wind farm uses only a fraction of the land area usually required for the operation of traditional wind farms. INVELOX is designed in such a way that it is less influenced by the vortex and wake effects that are caused by the large turbine blades rotation. These aerodynamic effects impose turbine spacing constraints on traditional wind farms, and cause them to take up much more space. INVELOX doesn’t face the same challenges as it has no rotating blades on the top the tower. On average, for a 100 MW project, INVELOX wind farms will use on average 90% less land than traditional wind farms. On the other hand, while the traditional wind turbines can only produce about 100 MW within 2,500 acres of land, an INVELOX wind power plant can generate about 1,400 MW on a similar surface.
INVELOX wind farms require much less land than traditional wind farms and use fewer towers, standing half as high as traditional wind turbines. As a result, the visual impact of an INVELOX wind farm on the landscape will be considerably reduced. INVELOX offers a notably superior aesthetic profile to communities.
Noise Impact and Shadow Flickers
Traditional wind turbines produce aerodynamic noise by the rotation of the blades, which can create annoyance and interference in the quality of life of nearby residents. It is noted that the damaging frequency range of the traditional turbine is below the hearing frequency of human ear, i.e., below 20 HZ. Low frequency noises and vibrations are harder to measure and noise experts still struggle to deal with these issues. Furthermore, the human organs, such as heart, lungs and brain have resonance frequencies below 20 HZ, and thus the turbine noise can create what is known as “Wind Turbine Syndrome.” By eliminating the need for massive tower mounted rotors, INVELOX significantly reduces the high energy and low frequency noise nuisance created by wind farms and eliminates entirely the shadow flicker issue.
Impact on Birdlife
Traditional wind farms represent a risk to birds due to collision with the rotating blades, interferences with migrations, and reduction or loss of habitat. INVELOX, thanks to the absence of rotating blades and its smaller land use, contributes to significantly reduce the negative impact on birds.
Aviation and Military Radars
Traditional wind farms can cause electro-magnetic interferences on aviation and military radars, and as a result cannot be installed in sites where such interference would occur. INVELOX turbines do not interfere with aviation and military radars, and can therefore be installed in areas inaccessible to traditional wind farms.
Distance from Grid
Traditional wind farms can only be installed in areas that have class–3 wind, which is a mean wind speed higher than 14 mph. these areas are often away from the electrical grid and main transmission lines. Therefore, connections need to be made between the remote area of the wind power plants and the regional transmission lines. The development of such connectivity is costly and time consuming. INVELOX wind farms can be installed much closer to the point of connection, and the connection works will be easier and cheaper to perform.
Traditional wind turbines, in cold climate areas, suffer from icing which results in performance degradation or shutdowns. Because INVELOX turbines and blades are safely installed at or below ground level, inside the venture section of the tower, they will not be subjected to harsh temperature variations and no icing will occur.
Because the INVELOX turbine and generator are safely placed at ground level, reliability will increase since they are not subjected to harsh environmental conditions. For example, bearings, shafts, blades, and gears are not exposed to broad temperature changes, humidity, airborne debris, and excessive winds. Our enclosed turbine-generator system will lead to reduced downtime, and result in more effective maintenance programs.
