UT Galveston Applauds Ocean Wave Energy Technology
Renewable energy doesn’t stop with earth, sun and wind. Now water is becoming a viable source for alternative power. Texas A&M has put Renewable Energy Oceanwave Technology from Indpendent Natural Resources to the test for three months in the Gulf of Mexico. The university says the SEADOG Pump is a preliminary success.
Researchers praised the pump’s design features for good mechanical efficiency that absorbs most of the potential energy and a significant amount of the kinetic energy content in the wave. This report further validates findings from a 21-day sea trial conducted in January of 2007 which compares the amount of energy SEADOG Pump can extract per square mile of deployment compared to other ocean, wind and solar renewable technologies. Because the pumps can be deployed in close proximity to each other, INRI(TM) estimates that they will produce five to 20 times more power per square mile than other technologies.
Generally speaking, wave energy is captured by engineered devices or components attached to stationary or floating structures that are set in motion by waves or swells on the surface of the ocean. Most wave energy technologies grow in cost because the specified equipment is sensitive to corrosive seawater and has intermittency issues similar to wind and solar energy. SEADOG Pump on the other hand, separates itself from other technologies on the market by using a simple pump design with few moving parts and no electronics. Multiple pumps are deployed in fields depending on how much power or water is desired. In addition, the SEADOG Pump moves large volumes of water to shore where it can be stored until needed for energy production or desalination. This ability to store energy removes the intermittency issues associated with other renewable energy technologies.
The lack of sufficient fresh water is a growing concern in many regions of the world, and seawater desalination is increasingly essential; Texas alone has more than 100 desalination plants. To further prove the SEADOG Pump’s commercial viability, INRI(TM) plans to launch an 18-pump field in the Gulf of Mexico between Galveston and Freeport, Texas. This commercial demonstration facility will desalinate seawater using the power generated by the 18 SEADOG Pumps.
Most wave-energy technologies involve off-shore electrical generation requiring the transmission of power to shore-based electrical grids. The SEADOG Pump captures energy from ocean swells or waves to pump seawater to land-based or sea-based holding areas, where the water can be returned to the ocean through turbines, thereby producing inexpensive, renewable electricity.

Dear Sir or Madame
An independent initiative Experts’ Group presents a brand new Wave Energy Converting Turbine MERABA. Please take your time to look at the description of the model and if you are interested, please contact us for future collaboration opportunities.
The main idea of our invention is a new and efficient way of utilizing energy of water waves. This is one of the important problems in modern technical science. Our version is different from all existing ideas and models known to us by simplicity of technical implementation: imagine a cable, one end of which is attached to a buoy on the sea, and the other end stretches to the shore. This cable runs in the same direction as the waves, floats on the water’s surface, and can rotate around its own axis. Under these circumstances, we can transfer the mechanical energy of the water waves to the shore. – A rotor with flexible fins attached perpendicularly to the axis – let’s call it a turbine for our purposes. Such a turbine would be turned either by the forward or backward motion of the sea waves. Many such turbines together can convert the energy of waves into other useful types of energy. This model is much simpler, stable and cheaper than any previous models known to us. Our idea can be thought of as on the new path for development of floating turbines. There are several advantages of the model:
1. Usually other such models utilize energy of a single wave during a particular phase of wave motion. In our model all waves along the length of the cable (length of which can be hundreds of meters) transfer part of their energy to the cable.
2. Any mechanical turbine needs to be rigidly attached to something, which creates additional technical complications. Our model is freely floating on a surface of water, so there are no difficulties related to stabilizing the turbine.
3. One of the significant problems of similar systems is the transport of the energy from the sea to the shore (by the electric cable on the bottom of the sea, for example). In our model, energy is naturally delivered to the shore for further utilization.
In April 8, 2009 at the laboratory of Oceanology of the Javakhishvili State University was held the presentation of the model. The presentation attended physicists of the University and other experts of the field. Here are some of their evaluations:
“The model of the turbine of simple and needs few materials. Thus it should be cheep and economically effective” -Emzar Khachidze, Expert of the Auditory Company “Centre of the Energy Inspection”
“The new principle of Transforming the wave energy into the mechanical energy, developed by Merab Chirakadze, is completely unknown in the field of renewable energy utilization of natural resources” – Prof. Doctor R. Pataraia, Chair of Hidroenergy Researches of the Institute of Energy of the Academy of Sciences of Georgia.
“invention of Merab Chirakadze is remarkable for its simplicity, This principle can be used in future as a foundation for new models” – Shalva Gagoshidze, Head of Laboratory of Marine Hydraulic Research of Georgia
