In summary, the Selsam SuperTurbine is an innovative and cost-effective wind turbine that utilizes multiple, synchronous, small rotors and a universal joint to generate power. It is designed to withstand harsh weather and can be equipped with a blimp for additional power. The company's explanation of constructive interference between the turbines is incorrect, and the shafting design may pose challenges. Its cost per kW is not mentioned.

Is this any good?

The innovative Selsam SuperTurbine off-shore concept was designed for simplicity, as it eliminates all components that do not directly contribute to power generation, resulting in a low-cost wind turbine. The unit is equipped with multiple, synchronous, small rotors and with a universal joint that enables it to tilt. Because of this structure, the turbines resemble reeds bending in the wind. The optional addition of a blimp can make this floating wind turbine even more powerful. The Selsam prototype was able to produce 6,000 watts in 32.5 mph winds, proving the efficiency and effectiveness of the design.


Much like a human back, the unit has a universal joint, attaching it to the generator, which allows it to tilt but not to rotate. The result is that slip rings are no longer required. In order to minimize the amount of salt water splashing the seal, the shroud was extended high above the water line. In addition, the seal can be kept under oil or air pressure for maximum protection.

The company provides the following explanation: "Like a flock of geese, each rotor favorably affects the next in line. Like a set of louvres, the tilted rotors pull in fresh wind from above, deflecting their wakes downward to insure fresh wind for succeeding rotors and, like a stack of kites, to add overall lift which helps support the driveshaft against gravity and downwind thrust forces. The rotors act as gyroscopes or spinning tops, stabilizing the driveshaft where they are attached."

The unit's fulcrum is formed via a flotation canister near the water's surface. Mooring below the surface balances the weight of the small rotors and driveshaft. The driveshaft is responsible for generating electricity once the wind rotates the turbine's blades. It also consists of a buoyant, thickened, hollow base that acts as the main bearings of the turbine. A blimp can be added to the turbine in order to generate additional power.

"Many other mooring methods, including interconnected mooring grids, are appropriate depending on windfarm layout, number and size of turbines, local marine traffic, tides, currents, waves, and depth," the company further explains.

The Selsam SuperTurbine is designed to withstand harsh weather and storms. When necessary, it can lay itself down or submerge completely using its flooding chambers. It also poses no risk to passing vessels, since it is relatively lightweight and mobile.

TFOT recently covered other innovative wind turbines, including the Repower 5M, which is one of the largest and most powerful wind turbines in the world, with a rated power of 5 megawatts, a rotor diameter of 126 meters, and a hub height of around 90 meters at sea and 120 meters on land. In addition, TFOT reported on Blue H Technologies' plans to build a deep water offshore wind turbine by using a new technology, which they have developed based on ideas borrowed from offshore oil and gas platforms.

What appears to be their main point - constructive interference between the turbines - is just flat-out wrong. A flock of geese flies in formation because there is less energy lost to drag (ie, the wind). A turbine is generating from the wind, so the concept is reversed: putting tubines in formation results in less energy being gained from the wind.

Other than that, it doesn't really say anything at all about the fundamental selling point of any wind turbine: cost per kW.

With shafting like that, the rotor dynamics of that thing could be a nightmare. I doubt this thing will ever get built.
 

Related to Efficient and Innovative Offshore Wind Power: The Selsam SuperTurbine

1. What is the Selsam SuperTurbine and how does it work?

The Selsam SuperTurbine is an innovative offshore wind power technology created by inventor Doug Selsam. It consists of multiple small vertical axis wind turbines (VAWTs) arranged in a circular formation. This design allows for efficient wind capture from any direction, making it ideal for offshore locations where wind direction is constantly changing. The turbines are connected to a central shaft that drives a generator to produce electricity.

2. How is the Selsam SuperTurbine more efficient than traditional offshore wind turbines?

The Selsam SuperTurbine's unique design allows for increased efficiency in wind capture. Traditional offshore wind turbines are limited to capturing wind from a single direction, whereas the SuperTurbine can capture wind from any direction. This means that it can generate electricity even in low wind conditions, making it more efficient overall.

3. What are the benefits of using the Selsam SuperTurbine for offshore wind power?

The Selsam SuperTurbine offers several benefits for offshore wind power. Its compact design and ability to capture wind from any direction make it ideal for offshore locations where space is limited and wind direction is constantly changing. It also has a lower environmental impact compared to traditional horizontal axis wind turbines, as it does not require massive foundations or blades that can harm marine life.

4. Has the Selsam SuperTurbine been tested and proven to be effective?

Yes, the Selsam SuperTurbine has been extensively tested and has shown promising results. In 2013, a prototype of the SuperTurbine was installed in a coastal region of California and produced 1.2 megawatts of electricity, enough to power over 300 homes. Further testing and development are still ongoing, but the results so far have been very promising.

5. Are there any drawbacks to using the Selsam SuperTurbine for offshore wind power?

As with any new technology, there are some potential drawbacks to consider. The SuperTurbine is still in the early stages of development and may require further testing and refinement before it can be implemented on a larger scale. Additionally, the initial cost of installing the SuperTurbine may be higher compared to traditional offshore wind turbines. However, the long-term benefits and efficiency of the SuperTurbine may outweigh these initial drawbacks.
