The United States Now Corporation is to acquire distribution rights to SP Power Farm Group’s exoPOWER wind turbine system for small-wind and mid-wind sectors for the states of Texas, New Mexico, Arizona, Nevada, Utah, Wyoming, Montana, North Dakota and South Dakota. All of them very windy areas!

So what’s different about SPpf’s exoPOWER wind turbine system compared to others? It is a proprietary, not yet patented technology whose design is based on the turbine blades being positioned on the circumference of a ring frame where multiple bearings and supports share the stress and torque of a rotating turbine equally. More detail? The outer ring is mounted on a track that is laid on the horizontal. As the turbine rotates, the magnets pass continuously along the mounted coil packs, where power off takes feed the converter, changing alternating current to direct current (AC to DC). The inverter then directs the power to the circuit breaker which flows back to the grid or to a battery storage system for on-demand electricity. Energy from the exoPOWER turbines can be taken off by a number of different methods, including coil and magnet, hydraulically and mechanically. Simple, versatile and relatively cheap. Is this the future  of smaller wind  turbines?

Of course we have to have a name for this type of turbine. It’s EWAT… with no relationship to the Star Wars Ewok! It stands for External Wind Axis Turbine. There’s no central hub that is common to conventional horizontal three-bladed axis wind turbines. In doing so, the  traditional nacelle which contains a complex yaw motor, transmission, gear and braking components, along with oil-based lubricants to keep everything in working condition is just not required. The turbines can be stacked on top of each other, making efficient land use, and can be installed directly into buildings or on roof-tops of new and existing buildings, allowing power to be generated where it is needed.

For you twitchers and bird conservationists out there,  an added benefit of this turbine design is that it will help prevent birds and other flying objects from striking the blades. It’s also intelligent- the turbine and housing can be raised using the ascending/descending tower so that higher wind loads can be exploited to optimize the generation of electrical power.

Company President Brian Sims said:

“We are extremely excited about our entry into the wind power generation sector. We believe we have secured certain rights to a technology that will disrupt the market place. Additionally, the alternative energy sector is one that has support from the public and governments all over the world. With the scalability of the exoPOWER wind turbine systems, the application for this technology is without limits. From an economic perspective, wind power generation is competitive, and with favorable governmental policies, coupled with a strong OEM partnership with pfBC, we have an opportunity to grow The NOW Corporation within a rapidly expanding sector.”
