Rogue River Wind, Ltd, (RRW) an Oregon renewable energy company has acquired the rights to a revolutionary new relativistic generator (REM) design. RRW is the developer of a ducted fan wind turbine, the V-LIM, capable of operating in low, high and turbulent winds up to Class 2 hurricanes. The V-LIM requires an equally robust, high bandwidth, direct drive generator capable of capitalizing on these powerful kinetic forces. The higher the RPM the more power the REM produces.

Until now modern generator technology began with Barlow and Faraday in England, and rather quickly matured through the dynamo into the recognizably modern generator by about 1900. The REM design represents the first radical design departure in generators since that time. The REM has no inductive wound coils. Plasma or laser cutters cut continuous and precise shapes simplifying manufacture. There is no inductive steel significantly reducing total weight. The design incorporates a magnet topology that requires only 1/5 the neodymium used in traditional generators. As a low resistance device there are no heating or cooling concerns.

The REM uses no flux targets so there is no magnetic hysteresis. The generator has low internal loss and no thermal loss. The generator operates at a high bandwidth, requires low starting torque and has zero cogging. The direct drive generator can be scaled and stacked to replace existing generators in traditional wind turbines and eliminate the need for gearboxes and reduce the weight at the top of a tower by over 2/3. These combined features result in a 15% efficiency gain over contemporary generator designs.

The general topology can be elementally reconfigured into all different generator design aspects and parameters, from axial to radial. It can function as stacked element generator in a traditional BIG WIND megawatt power mode, or as the power-generating element in a wind turbine based micro grid configuration. The REM can be used in a radial mode as wheel based motor in an electric vehicle design, or in water driven electrical generation modes. It can replace any traditional field coil or rare earth permanent magnet generator design in most applications, as an efficient coupling element between a mechanical power input, and an electrical power output. It can even be a stepper motor in a disk drive mechanism. The generator is available for license in any application where generators are required.
