Letter from Institute of Oceanology

A Statement From
Dr. Iliya Shtirkov,
Ocean Technologies Department
Institute of Oceanology
Bulgarian Academy of Science

It gives me great pleasure to endorse the CROWD ENERGY ocean energy turbine concept.
I have known the founder of CROWD ENERGY for over 25 years. His subsea engineering group have repeatedly demonstrated their ability to successfully design, build, implement, and operate large-scale subsea projects.
I am convinced that the CROWD ENERGY ocean turbine is a technologically viable project.
Crowd Energy has solved a problem that other ocean current turbines have not been able to address; specifically, utilizing the hydrodynamic power density of significant ocean currents efficiently.
From an engineering standpoint, a slow rotation/high torque turbine is much better for the marine environment.
Powerful ocean currents like the Gulf Stream and the Kuroshio are reliable and provide a constant source of clean renewable energy with minimal impact on the environment.
CROWD ENERGY is the right group to make this project happen based on their expertise and decades of experience.
I am personally excited to see their project come closer to realization. Of course some scale models and tests may require additional engineering improvement, but the idea is so interesting and promising.
It is clear that this dynamic subsea engineering group are dedicated to reducing the negative impact of fossil fuels on the environment and the success of their project will give benefits to the mankind.

Press Release
For Immediate Release

The founders of Crowd Energy (CE) are pleased to announce that a memorandum of understanding (MOU) has been executed between Florida Atlantic University (FAU) and CrowdEnergy.com
This MOU paves the way for collaboration between the two groups to facilitate the alpha and beta “proof of concept” prototype testing of Crowd Energy’s Ocean Energy Turbine.
The testing and anticipated performance validation will be done at FAU’s SOUTHEAST NATIONAL MARINE RENEWABLE ENERGY CENTER.
Based on a satisfactory outcome CE will relocate their R&D lab to an incubator on the FAU campus for further development.
CE’s founder Todd Janca has been progressing the design of the ocean energy turbine concept for over 9 years.
GE Power Systems reviewed the concept and responded that it was the “most innovative and viable concept that they had seen for harvesting the energy of the Gulf Stream”.

Eco Friendly Generator

Eco Friendly Generator:

The generator module has been specifically designed for the Ocean Energy Turbine. It is the result of eight years of research and testing.
Its primary goal is to not create any negative impact on the marine environment.
The second goal is to reach the maximum possible efficiency while providing decades of reliable service in a harsh ocean environment.
To achieve these goals required development of new technology.

Magnetically Shielded – The Ocean Energy Turbine’s generator is designed to be completely magnetically shielded. This shielding prevents the generator from producing any rotating magnetic fields or transverse electromagnetic radiation that could affect the surrounding marine environment. The power transmission lines are also shielded to prevent electromagnetic radiation. Every effort has been made to ensure the protection of the environment.

Direct drive – By designing around direct drive technology we have greatly reduced the number of moving parts and greatly increased long term reliability. Direct drive drastically reduces service and maintenance intervals resulting in reducing potential down time. Direct drive is also an average of 30% more efficient than conventional transmission and variable torque power generation.

Harmonic Damping – The Ocean Energy Turbine’s generator is designed to have one moving part that is precision balanced for the reduction of harmonic vibration. The absence of brushes, commutators, clutches, gears, and transmissions in the generator design allow the generator to produce maximum power without producing vibrations “noise” that could disturb the marine environment.

CrowdEnergy is in the process of filing a number of additional patents covering technologies that are unique to the Ocean Energy Turbine and its generator.

Ocean Energy Turbine Test Tank

Turbine Test Tank

The Laminar flow test tank will be 10′ x 20′ x 5’deep with an over tank work platform and a 30″ x 60″ viewing window in the side. The test tank will be built from a steel square tube frame lined with multiple layers of marine plywood and coated with a liquid rubber membrane. After pricing a number of “prebuilt” test tanks, we decided to build our own tank to conform to our limited budget. The water flow in the tank is generated by four 5hp pumps arranged to turn half of the tank into a eductor, so we can use a small fast flow of water to circulate a large volume of water in the tank. Once again, the improvised eductor arrangement was decided on to fit the budget. The tank will be built where it can be transported by Semi truck, and when we have completed using it for testing, we will donate it to a local university.
