The GyroWaveGen(TM)/(a.k.a. 'GyroGen(TM)') uses a gyroscopic flywheel to provide a variable inertial resistance, or "virtual mass" against which oscillations induced by waves can be converted to usable mechanical and electrical energy (by conversion of gyroscopic precession motion and torque). The original GyroGen(TM) was invented in 1979 and remains the only "active", autonomously adaptive, and tunable wave energy converter in existence. This is in contrast to the much more common types of 'passive systems', which cannot respond as quickly, or as broadly, to waves having widely different heights and frequencies. Its unique principles of operation, also lets the technology offer many additional advantages over other types of wave energy conversion methods. Among these advantages is its significantly smaller size and much lower weight, its ability to be much more easily transported and its ease of servicing, as a result of all its moving parts being located above water. Indeed, one of its most important and unique features is the complete isolation and sealing off, of all its moving parts from contact with the harsh ocean environment, including corrosive salt water and sea spray, and fouling agents such as ocean organisms, seaweed and human introduced garbage, such as netting and plastic waste (which, by comparison, is a big problem for passive technologies, that can't be totally isolated from the ocean environment). The GyroGen's compact design and lighter weight will also make possible much easier transport by train, truck and even helicopter. The later feature being especially useful if, and when, GyroGen's could be used for providing emergency power in a disaster scenario. Its first likely use would be in providing wave-generated power to island and coastal communities.

Patents Issued and Pending

First patent for the GyroGen(TM)/GyroWaveGen(TM)

4,352,023, additional patents pending.


The technology is undergoing ongoing design evolution, testing and computer simulation. Additional patents have been filed covering these enhancements. Prototypes combined with computer simulations allow accurate evaluation of design variables, without multiple devices having to be built and tested. Efforts towards commercializing this technology are in part dependent on locating additional sources of funding, including from outside investors, and/or strategic partnerships.


Among the many distinct advantages of this technology is its ability to completely isolate the gyroscopic transducer/generator set and all moving parts from the harsh ocean environment. Additional advantages of the technology are that it is easy to scale, it is highly modular and robust, it is very easy to move and maintain (even at sea) and it can be manufactured and deployed at relatively low cost (compared with wind turbines and other wave energy converters). Also, because the technology can be mounted above water, permitting should be simpler than for competing devices that operate below water.

US Patent 4,352,023 - Mechanism for generating power from wave motion on a body of water Herbert K. Sachs and George A. Sachs September 28, 1982

Abstract : A mechanism for generating power from wave motion on a body of water. The mechanism includes a buoyant body which is adapted to float on a body of water and to roll and pitch in response to the wave motion of the water. A gyro-wave energy transducer is mounted on the buoyant body for translating the pendulum-like motions of the buoyant body into rotational motion. The gyro-wave energy transducer includes a gimbal comprised of first and second frames, with the first frame being pivotally mounted to the second frame and the second frame being pivotally mounted to the buoyant body. A gyroscope is mounted to the first frame for rotation about an axis perpendicular to the axes of rotation of the first and second frames. A motor/generator is coupled to the gyroscope for maintaining a controlled rotational velocity for the gyroscope. Transferring members are associated with one of the first and second frames for transferring torque of one of the first and second frames to the gyroscope about an axis that is perpendicular to that of the gyroscope which results in rotation of the other of the first and second frames. An electrical generator is responsive to the relative rotational movement of the first and second frames for generating electrical energy. A storage battery is mounted on the buoyant body for storing and releasing electrical energy and is operatively coupled to the motor/generator and the electrical generator. A control circuit is associated with the generator and the motor/generator unit of the gyroscope and is responsive to the time rate of change of current produced by the generator for controlling the rotational velocity of the gyroscope in order to maintain maximum power output from the electrical generator.

Additional patents are pending.

The core of the technology along with additional advancements that have been made are presently held as proprietary information, either in the form of patents, trade secrets, test data, design data, copyrighted documents, trademarks and domain names.
