Wind Acceleration Modular (WAM) Arrays are the first technology V 2
is developing using its proprietary fluid accelerators. V 2
's WAM arrays passively accelerate the wind, increasing the extractable power and energy intensity. They are projected to generate electricity at a cost below any competing technologies, fossil or renewable, without subsidies.
A 4kW array of four 1kW modules is pictured below.
WAM Arrays are the only technology that has the potential to meaningfully supply urban electricity demand with urban generation other than natural gas which has dominated this market based on its high supply intensity and low upfront capital costs.
By accelerating the ambient wind speed, WAM arrays can be widely deployed in the low wind speeds areas which consitute 95% of urban areas globally. Urban areas cannot be effectively supplied by current RE technologies due primarily to their low energy intensity and secondarily their cost. WAM Arrays’ energy intensity, cost, and modular flexibility change the game for Distributed and Renewable Energy. They can supply greater than 25% of the existing and growing need for urban generation at lower cost than the delivered cost of ex-urban centralized power plants or urban fossil facilities. This limits the required investment in new transmission capacity, reduces transmission operating and maintenance costs and offsets urban and ex-urban fuel costs and emissions.
WAM Arrays can be deployed as stand-alone generation or in cogeneration with Natural Gas.
HOW THEY WORK
The simplest explanation is that the accelerators passively increase the proportion of dynamic pressure (effectively equivalent to Kinetic Energy) in the fluid. For wind power generation that directly translates to an increase in the energy intensity of the system. The level of increase is determined by the rate of acceleration, Power increase = rate of acceleration 3
. A 2x acceleration yields 8x power, a 2.5x acceleration 15.6x power, etc.. V 2
's accelerators are the first accelerators to achieve acceleration above 1.5x. Details of V 2
's accelerator and array performance can be found in the VALIDATION section.
When combined with modularity, the system's energy intensity (power generated per unit area) is orders of magnitude higher than any other clean technology and on par with fossil. Its deployment flexibility (rating and physical dimensions) exceeds all other generation technologies including solar. Modularity also mitgates the other problem wind accelerators have faced in the past, the structural and materials costs needed to produce the acceleration. In modular systems that structure (most importantly the elevation structure) is distributed over the entire system, substantially reducing the structure and materials required to accelerate the wind.
The modularity and acceleration combine to create a wind generation technology that has high energy intensity and deployment flexibility and low cost. In today's energy landscape the competitive advantage of those features cannot be overstated. Applications for the modular system can range from DE kW rooftop installations to MW utility installations and all applications in between. Some examples of deployable locations are shown below.
