THOR's ROC-Flume Operational
THOR designed, built and now owns and operates its own open channel recirculating water flume that has unique water current simulation capabilities, including;
- Ability to tailor water speed versus depth profile (vertical sheer) on demand via 24 individually controllable thruster motors
- Programmable water current run schedules that change flow speeds and sheer characteristics from one predetermined state to another predetermined state (i.e. simulate changing flow conditions over time like ocean current variations or tidal forward/reverse conditions)
- Speeds up to 2.5m/s forward flow and 1.5m/s reverse flow direction
- Ability to simulate flow turbidity characteristics by pulsing individual thruster throttle controls
- Ability to simulate upstream waked flow by adjusting individual thruster throttle controls
THOR's ROC-Flume includes a variable position acoustic Doppler velocimeter (ADV), a fixed acoustic Doppler current profiler (ADCP) and a multi-level pitot tube array for precise water current speed measurements in the 8 foot deep, 4 foot wide test section. THOR will deploy a scaled model of its ocean current turbine in the ROC-Flume later this summer and expects to conduct a systematic testing program lasting about 6 months.

THOR's ROC-Flume Nearing Operational Status
THOR's unique open channel re-circulating ocean current flume (ROC-Flume) took one large leap forward today with the final delivery to THOR's Fairfax, OH facility. The ROC-Flume is capable of creating time variant inverse velocity sheer water currents that closely mimic real world ocean current behavior. The ROC-Flume will be used to further develop and fine tune THOR's Power Method - a method of operating an ocean current turbine that promises to deliver 'always-on', base-load energy 24x7x365. THOR is presently developing 2 scale models for deployment into the ROC-Flume later this summer.

THOR Takes Delivery of the ROC-Flume Hydrodynamic Testing Container Shell
THOR accepted delivery today of what will become the world's only open channel recirculating water flume capable of creating time variant inverse velocity sheer water currents that closely mimic real world ocean current behavior. Over the next 45-60 days, the ROC-Flume will be outfitted with a variety of new hardware including end returns, motor shelves, flow dividers, two ADCPs, a pitot tube array, mooring facilities, test section viewing windows, as well as the computer hardware and software required to run the entire ROC-Flume facility. At full power, the 8x4 thruster motor array with 32 individually programmable and controllable fully submerged propeller driven electric motors will draw some 60 kilowatts (kW) from Duke Energy's electrical service installed at THOR's Fairfax, Ohio building. Turner Hunt remarked that, "THOR's Fairfax facility is a perfect venue to house this revolutionary new hydrodynamic testing facility that will form the basis for the validation of our breakthrough ocean current turbine power control method [THOR's Power Method] that will vault ocean current energy into the base-load power generation category".

THOR Completes Model Scale Electrical Generator Dynamometer - the Dyno-THOR
Because power feedback and control is an important aspect of THOR's ocean current turbine technology, the need to test, calibrate and measure the power output from electrical axial flux generators that will be constructed and installed in THOR's scale model renewable ocean current turbine (ROCT) while the scale model operates in the ROC-Flume is a very important aspect of the scale model control system. A generator dynamometer, which measures torque and power input, as well as torque, power and electrical energy output from the generator mounted in the dynamometer is an indispensible testing apparatus to measure and calibrate each particular generator that will be used with the scale model ROCT. Upon completion of the Dyno-THOR today, Turner Hunt remarked, "Since the measure of the generator's power output is one of the primary feedback parameters in the control of our scale model ROCT, we need to understand how clean we can expect the power signal to be and how it varies with RPM, input torque and other parameters. The Dyno-THOR also provides a water tight enclosed volume into which we can submerge each electrical generator to understand operation in the fully submersed environment prior to deployment in the ROC-Flume for continued research, development and testing.

THOR Applaudes Atlantic Wind Connection's Proposed HVDC Transmission Line off the Coast of VA, DE, MD, NJ & NY
THOR today applauded the Atlantic Wind Connection's (AWC) proposed HVDC undersea transmission line of the coasts of VA, DE, MD, NJ & NY intended to jump start to development and deployment of offshore wind farms off the coast of the Northeastern United States. Atlantic Wind Connection is backed by Trans-Elect, Good Energies, Google and Marubeni Corp. There are currently a half dozen offshore wind farms now going through the Bureau of Ocean Energy Management's review process to build offshore wind farms off the coast of the Northeastern United States. The AWC proposed submarine HVDC transmission line will have a capacity of 6,000MW – but on average will only have 2,400MW flowing through it given the 40% (or so) capacity factor if all these proposed offshore wind farms were actually built. That leaves 3,600MW of 'wasted capacity' in the line owing mainly to the intermittency of the wind resource. If AWC were to extend their HVDC line 'around the NC outer bank corner' to the Gulf Stream area, THOR could design/deploy an ocean current farm array that could effectively fill the AWC transmission line and keep it at full capacity (using THOR's power feedback technology) when the wind in the Northeast was not blowing, or not blowing enough to keep the line at capacity. Thus the AWC line could carry clean renewable energy from both wind and ocean current.

THOR Files Application for Funding in Responses to the US Dept. of Energy Funding Opportunity Announcement (FOA) for Marine Hydrokinetic Energy
THOR filed its application in response to the Dept. of Energy's Wind and Water Program FOA for marine and hydrokinetic energy today for a research and development effort aimed at a technology readiness level four (TRL4 – 'scale model in a laboratory environment') demonstration and validation of the Company's breakthrough THOR's Power Method by proposing the construction of a unique water flume hydrodynamic testing facility to house/test/validate a scale model of THOR's renewable ocean current turbine (THOR's ROCT). Turner Hunt remarked, "With this application, and if we are lucky enough to be selected by the DoE review staff, we have a chance to clearly demonstrate over the course of the project that renewable energy has a new, viable and base-load fuel type, namely ocean current energy which has been mostly overlooked in favor of the other hydrokinetic 'fuel types' which include moving water from tidal, wave, and river based resources. We hope to demonstrate, through the use of our technology, that ocean current energy is the only hydrokinetic fuel source that can truly provide base-load power generation with capacity factors in excess of 80%".

THOR compiles Southeastern USA CODAR and WERA Ocean Current Surface Speed Data
In a continuing effort to assess and quantify the Gulf Stream as a potential renewable energy resource, THOR, LLC announced today that is has completed compilation of a comprehensive ocean current surface speed database spanning 10 years' worth of data from all available Coastal Observation and Data Acquisition Radar (CODAR) and (Wave Radar) WERA system measurements taken by instruments deployed on the Southeastern United States Coastline. There are currently 3 such high frequency radar systems (HF-Radar) operated by the (1) Univ. of Miami Rosenstiel School of Marine and Atmospheric Science operates a WERA system that covers some 100 sq. miles south of Miami, FL, (2) the Skidaway Institute of Oceanography operates a WERA system near Savannah, GA that extends radial arcs over 100 miles offshore to capture the Gulf Stream surface currents in the 'Great Bend' as the Gulf Stream turns Northeastward on its way up the SC and NC coastlines and (3) the University of North Carolina Chapel Hill operates a CODAR system off Duck and Hatteras, NC. This data was obtained from each of the three sources as well as the National Data Buoy Center. An SQL database was used to store the data and provide quick retrieval of specific time segments for various analysis purposes. THOR was able to generate geospatial location specific speed contour maps for the Gulf Stream ocean current in these 3 regions and analyze the statistical trends in the current speed data and direction of travel. Preliminary analysis of the compiled data show a remarkably consistent current flow that does not meander outside of the core centerline area with ranges of directional change and standard deviations in current speed.
