Several decades ago, scientists were in disagreement as to which type of turbine would be beneficial to the industry. After extensive research on both types of turbines, the Horizontal Axis Wind Turbines (HAWT) won the battle, not because it was a great turbine but because scientists at that time were unable to solve the major problems associated with the Vertical Axis Wind Turbines (VAWT) and they were also fixated on efficiency.
How Wind Turbines WorkWind turbines are categorized as either lift or drag turbines. The blades on lift type turbines travel faster than the speed of the wind and the airfoil shaped blades receive lift and drag similar to the wings of an airplane. Lift is the component that provides the power to the turbine. Drag wind turbines travel slower than the wind speed, have a much lower efficiency, and require more material to produce the same power as a lift type turbine. Drag machines are never used in commercial applications.
The Lux Wind TurbineOur turbine is a 5 bladed VAWT. Several cables are connected between each blade in a cross pattern, which supports each blade along its entire length. This rotor is a rigid structure never seen before in the wind industry. Due to this cross cabling, the central structure/tower can be removed, which is the main reason why the turbine can be built using less materials producing a lower LCOE.
Lux Wind Power is a Vertical Axis Wind Turbine Manufacturer, but at this time, our turbine is for research purposes only. We do not claim to build the most efficient turbine, but we do believe we can build a turbine that will produce energy at a lower cost than other turbines of equal size. That is, the Levelized Cost of Energy (LCOE), which is the lifetime costs divided by the lifetime energy production, on our turbine is expected to be lower than on the HAWT.
Are Vertical Axis Wind Turbines better than Horizontal Axis Wind Turbines?The answer is, only if the LCOE is lower. The LCOE is not dependent on efficiency or extracting power from winds high above the earth. It is simply the cost of producing energy. The LCOE of a VAWT can be lower for the following reasons:
We believe our wind turbine has a lower LCOE for all the above reasons.
The Institute of Aerospace Research, a branch of the National Research Council (NRC), in Ottawa, Canada developed computer models of the Lux turbine and tested these models for aerodynamic and structural performance. The first model they analyzed was 40 meters in diameter and had a power output of 1MW. The results of the analysis showed the Lux Wind Turbine performed well and the blades had a life expectancy well in excess of 25 years.NRC then scaled the computer models to a diameter of 160 meters with a power output of 16MW. The positive results observed in the 1MW turbine analysis were repeated with the larger turbine.
IOPARA, a Vertical Axis Wind Turbine consulting company, in Montreal, used their CARDAAV software, which is well respected around the world, to predict the power output of several Lux Turbine models with and without cross cables. The power curves created from this software were confirmed with data collected from the prototypes. The power loss from the cross cables was low, as expected.
The first generation of the 40KW Lux Wind Turbine was operational for 1½ years. It was then lowered and 7 other models were assembled and tested for various periods of time. Variations of blade curvature, blade offset angles, solidity ratios, blade profiles, drivelines and air brakes, were applied to these models, with the goal of optimizing turbine performance.
The least expensive option uses 3 guy cables that go from the top of the rotor to an anchor on the ground. This turbine does not need a central structure/tower or a robust foundation to keep the rotor upright. The guy cable and anchor system is only a fraction of the cost of the traditional robust cement foundation and tower system. This turbine can be used in most rural areas and could reduce the cost of the support structures in offshore locations as well.
In locations where it isn''t feasible to use guy cables, the rotor is supported by a lattice structure positioned along the vertical axis that rotates with the blades. The cross cable pattern is still utilized so the blades have very little movement even in hurricane wind conditions. This system requires a robust foundation but the blade, lattice tower and cross cable system is expected to have a cost that is significantly lower than the conventional wind turbines.
